方法一通过GridView(简评：方法比较简单，但是只适合生成格式简单的Excel，且无法保留VBA代码),页面无刷新

aspx.cs部分

复制代码代码如下:

using System;

using System.Collections;

using System.Configuration;

using System.Data;

using System.Web;

using System.Web.Security;

using System.Web.UI;

using System.Web.UI.HtmlControls;

using System.Web.UI.WebControls;

using System.Web.UI.WebControls.WebParts;

using System.Text;

public partial class DataPage_NationDataShow : System.Web.UI.Page

{

private Data_Link link = new Data_Link();

private string sql;

protected void Page_Load(object sender, EventArgs e)

{

Ajax.Utility.RegisterTypeForAjax(typeof(DataPage_NationDataShow));

}

protected void btnExcel_Click(object sender, EventArgs e)

{

string strExcelName = "MyExcel";

strExcelName = strExcelName.Replace(@"/", "");

Data_Link link = new Data_Link();

string strSQL = this.hidParam.Value;

DataSet ds = new DataSet();

ds = link.D_DataSet_Return(strSQL);//获得想要放入Excel的数据

gvExcel.Visible = true;

gvExcel.DataSource = null;

gvExcel.DataMember = ds.Tables[0].TableName;

gvExcel.DataSource = ds.Tables[0];

gvExcel.DataBind();

ExportToExcel(this.Page, gvExcel, strExcelName);

}

protected void gvExcel_RowDataBound(object sender, GridViewRowEventArgs e)

{ }

public override void VerifyRenderingInServerForm(Control control)

{ }

/// <summary>

/// 工具方法，Excel出力(解决乱码问题)

/// </summary>

/// <param name="page">调用页面</param>

/// <param name="excel">Excel数据</param>

/// <param name="fileName">文件名</param>

public void ExportToExcel(System.Web.UI.Page page, GridView excel, string fileName)

{

try

{

foreach (GridViewRow row in excel.Rows)

{

for (int i = 0; i < row.Cells.Count; i++)

{

excel.HeaderRow.Cells[i].BackColor = System.Drawing.Color.Yellow;

}

excel.Font.Size = 10;

excel.AlternatingRowStyle.BackColor = System.Drawing.Color.LightCyan;

excel.RowStyle.Height = 25;

page.Response.AppendHeader("Content-Disposition", "attachment;filename=" + fileName);

page.Response.Charset = "utf-8";

page.Response.ContentType = "application/vnd.ms-excel";

page.Response.Write("<meta http-equiv=Content-Type content=text/html;charset=utf-8>");

excel.Page.EnableViewState = false;

excel.Visible = true;

excel.HeaderStyle.Reset();

excel.AlternatingRowStyle.Reset();

System.IO.StringWriter oStringWriter = new System.IO.StringWriter();

System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter);

excel.RenderControl(oHtmlTextWriter);

page.Response.Write(oStringWriter.ToString());

page.Response.End();

excel.DataSource = null;

excel.Visible = false;

}

catch (Exception e)

{

}

aspx部分

复制代码代码如下:

//Excel DownLoad

function excelExport(){

var hidText = document.getElementById("hidParam");

hidText.value = "some params";

document.getElementById("ExcelOutput").click();

}

</script>

</head>

<asp:Button runat="server" ID="ExcelOutput" Text= "EXCEL出力" Width="0px" UseSubmitBehavior="false"/>

<asp:GridView ID="gvExcel" runat="server" Height="95px" OnRowDataBound="gvExcel_RowDataBound" Visible="False"></asp:GridView>

</form>

</body>

在刚才的aspx.cs代码中

复制代码代码如下:

foreach (GridViewRow row in excel.Rows)

{

for (int i = 0; i < row.Cells.Count; i++)

{

excel.HeaderRow.Cells[i].BackColor = System.Drawing.Color.Yellow;

}

这部分是给表头添加样式。

有时候为了便于浏览，需要给交叉行添加样式，简单点的可以用下面这种：

复制代码代码如下:

excel.AlternatingRowStyle.BackColor = System.Drawing.Color.LightCyan;

但是细看一下会发现它把一整行的样式都改变了，包括后面那些没有用到的列。

asp.net生成Excel并导出下载五种实现方法1

解决办法是有，不过比较繁琐，就是修改每个单元格的样式。

复制代码代码如下:

int rowCount = excel.Rows.Count;

int colCount = excel.HeaderRow.Cells.Count;

for (int i = 0; i < rowCount; i++)

{

for(int j=0;j<colCount; j++)

{

excel.Rows[i].Cells[j].BackColor = System.Drawing.Color.LightCyan;

}

方法二通过DataGrid(与方法一基本相同),页面无刷新

aspx.cs部分

复制代码代码如下:

public override void VerifyRenderingInServerForm(Control control)

{}

/// <summary>

/// エクセル出力イベント

/// </summary>

/// <param name="sender"></param>

/// <param name="e"></param>

private void ExcelBut_Click(object sender, System.EventArgs e)

{

DataGrid dgExcel = new DataGrid();

try

{

DataSet ds = getExcelData(this.PageParams.Value);//出力データを取得する

if(ds.Tables[0].Rows.Count>0)

{

//エクセルへデータを投入する

string execlName= "MyExcel";

Encoding encodingType=System.Text.Encoding.UTF8;

dgExcel.DataMember=ds.Tables[0].TableName;

dgExcel.DataSource=ds.Tables[0];

Response.Buffer = true;

Response.Charset = "utf-8";

Response.AppendHeader("Content-Disposition", "attachment;filename=" + execlName+ ".xls");

Response.ContentEncoding = encodingType;

Response.ContentType = "application/ms-excel";

StringWriter oStringWriter = new StringWriter();

HtmlTextWriter oHtmlTextWriter = new HtmlTextWriter(oStringWriter);

dgExcel.DataBind();

dgExcel.Visible = true;

dgExcel.RenderControl(oHtmlTextWriter);

Response.Write(oStringWriter.ToString());

Response.Flush();

Response.Close();

dgExcel.DataSource = null;

dgExcel.Visible = false;

}

else

{

Response.Write("<script>alert('xxxxxx')</script>");

}

catch(Exception ex)

{

Response.Write("<script>alert('oooooo')</script>");

}

aspx部分

复制代码代码如下:

//Excel DownLoad

function excelExport(){

var hidText = document.getElementById("hidParam");

hidText.value = "some params";

document.getElementById("ExcelOutput").click();

}

</script>

</head>

<asp:Button runat="server" ID="ExcelOutput" Text= "EXCEL出力" Width="0px" UseSubmitBehavior="false"/>

<asp:datagrid id="gvExcel" Visible="False" Runat="server"

Width="80px" Height="40px"></asp:datagrid>

</form>

</body>

方法三以XML形式的Excel方式(可以设置丰富的样式，并可以有多个sheet，但需要模版。速度很快，但生成的文件较大，且无法保留VBA代码)

具体方法：把模版以 XML Document形式另存为A.xml。然后参照A.xml中的内容即可

复制代码代码如下:

private void ExcelBut_Click(object sender, System.EventArgs e)

{

DataSet ds = new DataSet();

string ExcelFileName = "";

DataRow dr=[------列名信息-------];

try

{

ExcelFileName = Path.Combine(Request.PhysicalApplicationPath + "/ExcelFile", "MyExcel.xls");

//获取Excel需要的数据

ds = [------获得数据-------];

if (ds.Tables.Count == 0)

{

Response.Write("<script type='text/javascript'>alert('无数据');</script>");

return;

}

int sheetNum = ds.Tables.Count / 2;

StreamWriter writer = new StreamWriter(ExcelFileName, false);

//Styles标签前面的信息相当于'头信息'，不需要改变

writer.WriteLine("<?xml version="1.0"?>");

writer.WriteLine("<?mso-application progid="Excel.Sheet"?>");

writer.WriteLine("<Workbook xmlns="urn:schemas-microsoft-com:office:spreadsheet"");

writer.WriteLine("xmlns:o="urn:schemas-microsoft-com:office:office"");

方法四用微软的COM组件操作Excel。虽然可以很方便的操作单元格，并且能保留VBA代码，它相当于直接打开一个EXCEL进程。

当初这个COM组件式给WinForm准备的，但在Web端有很多东西的支持不尽人意，例如无法用组件中的方法关闭Excel对象，

只能通过强制关闭Excel进程的方式(这其中还有很多问题，例如只能关闭当前打开的这个Excel的进程，否则会把其他用户的Excel进程关闭)。在这里不推荐

方法五用流的方式，把内容以Table的格式向Excel中放数据好处是可以生成格式丰富复杂的Excel，页面无刷新

aspx部分

复制代码代码如下:

<asp:Button ID="hidExport" Runat="server"></asp:Button>

aspx.cs部分

复制代码代码如下:

//内容很好理解，只需当成Table来拼字符串即可

private string getExcelContent()

{

StringBuilder sb = new StringBuilder();

sb.Append("<table borderColor='black' border='1' >");

sb.Append("<thead><tr><th colSpan='2' bgColor='#ccfefe'>标题</th></tr>");

sb.Append("<tr><th bgColor='#ccfefe'>号码</th><th bgColor='#ccfefe'>名字</th></tr></thead>");

sb.Append("<tbody>");

sb.Append("<tr><td bgcolor='#FF99CC'></td><td></td></tr>");

sb.Append("<tr><td></td><td bgcolor='lightskyblue'></td></tr>");

sb.Append("</tbody></table>");

return sb.ToString();

}

private void hidExport_Click(object sender, System.EventArgs e)

{

string content = getExcelContent();

string css = ".firstTR td{color:blue;width:100px;}.secondTR td{color:blue;width:100px;}";

string filename = "Test.xls";

CommonTool.ExportToExcel(filename, content ,css);

}

工具类CommonTool

复制代码代码如下:

public class CommonTool

{

/// <summary>

/// 以流的形式，可以设置很丰富复杂的样式

/// </summary>

/// <param name="content">Excel中内容(Table格式)</param>

/// <param name="filename">文件名</param>

/// <param name="cssText">样式内容</param>

public static void ExportToExcel(string filename, string content,string cssText)

{

var res = HttpContext.Current.Response;

content = String.Format("<style type='text/css'>{0}</style>{1}",cssText,content);

res.Clear();

res.Buffer = true;

res.Charset = "UTF-8";

res.AddHeader("Content-Disposition", "attachment; filename=" + filename);

res.ContentEncoding = System.Text.Encoding.GetEncoding("UTF-8");

res.ContentType = "application/ms-excel;charset=UTF-8";

res.Write(content);

res.Flush();

res.End();

}

这种方法比较灵活，而且可以通过选择器来添加样式，相当不错。缺点就是需要将数据转换成字符串。
