写图片c:1.jpg到表cinfo中
复制代码 代码如下:
private static void AddCinfo()
{
string strSql = "insert into cinfo (srvtitle,csttitle,introduction,logo) values
(@srvtitle,@csttitle,@introduction,@logo)";
SqlParameter[] parms =
{
new SqlParameter("@srvtitle",SqlDbType.VarChar,30),
new SqlParameter("@csttitle",SqlDbType.VarChar,30),
new SqlParameter("@introduction",SqlDbType.NVarChar,500),
new SqlParameter("@logo",SqlDbType.Image)
};
parms[0].Value = "旅业互动";
parms[1].Value = "lyhd";
parms[2].Value = "简介";
string filePath = @"c:1.jpg";
FileStream fs = File.OpenRead(filePath);
byte[] content = new byte[fs.Length];
fs.Read(content, 0, content.Length);
fs.Close();
parms[3].Value = content;
DBHelper.ExecuteNonQuery(CommandType.Text, strSql, parms);
}
读取图片的页面 test.aspx
复制代码 代码如下:
protected void Page_Load(object sender, EventArgs e)
{
string strSql = "select * from cinfo where id=1";
SqlDataReader reader=DBHelper.ExecuteReader(CommandType.Text, strSql, null);
if(reader.Read())
{
byte[] c=(byte[])reader["logo"];
Response.BinaryWrite(c);
}
}
