在本文中我们将学习win 8中的文件以及文件夹的各种操作。
在本文中文件操作主要是讲述：删除文件/移动文件/复制文件/重命名文件
文件夹操作分为：读取文件夹/创建文件夹/删除文件夹/重命名文件夹
首先贴出所有的Xaml代码文件部分：
<Grid Background="{StaticResource ApplicationPageBackgroundThemeBrush}">
<>
<TextBlock HorizontalAlignment="Left" Margin="137,42,0,0" TextWrapping="Wrap" Text="文件名:"
VerticalAlignment="Top" Height="23" Width="43"/>
<TextBox HorizontalAlignment="Left" Margin="185,33,0,0" TextWrapping="Wrap"
Text="test.txt" VerticalAlignment="Top" Width="121" Name="tbFileName"/>
<TextBox HorizontalAlignment="Left" Margin="457,33,0,0" TextWrapping="Wrap"
Text="默认需要添加的文件内容" VerticalAlignment="Top" Width="431" Name="tbContent"/>
<TextBlock HorizontalAlignment="Left" Margin="396,42,0,0" TextWrapping="Wrap" Text="文件内容："
VerticalAlignment="Top" Height="23" Width="61"/>
<TextBlock HorizontalAlignment="Left" Margin="127,163,0,0" TextWrapping="Wrap" Text="提示："
VerticalAlignment="Top" Height="23" Width="761" Name="tb_show"/>
<>
<Button Content="创建并写入文件" HorizontalAlignment="Left" Margin="127,99,0,0"
Name="btnCreateFile" VerticalAlignment="Top" Click="btnCreateFile_Click"/>
<Button Content="读取string文件" HorizontalAlignment="Left" Margin="757,99,0,0"
x:Name="btnReadFile" VerticalAlignment="Top" Click="btnReadFile_Click"/>
<Button Content="删除文件" HorizontalAlignment="Left" Margin="127,223,0,0"
x:Name="btnDeleteFile" VerticalAlignment="Top" Click="btnDeleteFile_Click"/>
<Button Content="移动文件" HorizontalAlignment="Left" Margin="320,223,0,0"
x:Name="btnMoveFile" VerticalAlignment="Top" Click="btnMoveFile_Click"/>
<Button Content="复制文件" HorizontalAlignment="Left" Margin="560,223,0,0"
x:Name="btnCopyFile" VerticalAlignment="Top" Click="btnCopyFile_Click"/>
<Button Content="重命名文件" HorizontalAlignment="Left" Margin="780,223,0,0"
x:Name="btnReNameFile" VerticalAlignment="Top" Click="btnReNameFile_Click"/>
<>
<Button Content="读取文件夹" HorizontalAlignment="Left" Margin="127,296,0,0"
VerticalAlignment="Top" Name="readFolder" Click="readFolder_Click"/>
<Button Content="创建文件夹" HorizontalAlignment="Left" Margin="305,296,0,0"
VerticalAlignment="Top" x:Name="btnCreateFolder" Click="btnCreateFolder_Click"/>
<Button Content="删除文件夹" HorizontalAlignment="Left" Margin="545,296,0,0"
VerticalAlignment="Top" x:Name="btnDeleteFolder" Click="btnDeleteFolder_Click"/>
<Button Content="重命名文件夹" HorizontalAlignment="Left" Margin="766,296,0,0"
VerticalAlignment="Top" x:Name="btnReNameFolder" Click="btnReNameFolder_Click"/>
</Grid>
其次我们来看删除文件/移动文件/复制文件/重命名文件的Cs代码：
private async void btnDeleteFile_Click(object sender, RoutedEventArgs e)
{
try
{
StorageFile sf = await storageFolder.GetFileAsync(this.tbFileName.Text.Trim());
await sf.DeleteAsync();
tb_show.Text = "提示:" + this.tbFileName.Text.Trim() + "文件删除成功!";
}
catch (Exception ex)
{
tb_show.Text = "提示:未找到该文件，请先创建文件";
}
}</p> <p> private async void btnMoveFile_Click(object sender, RoutedEventArgs e)
{
try
{
//将文件从文档移动到音乐库
StorageFile sf = await storageFolder.GetFileAsync(this.tbFileName.Text.Trim());
StorageFolder newfolder = KnownFolders.MusicLibrary;
await sf.MoveAsync(newfolder, "moveFile.txt", NameCollisionOption.ReplaceExisting);
tb_show.Text = "提示:“库文档" + this.tbFileName.Text.Trim() + "”文件移动到“库音乐moveFile.txt”";
}
catch (Exception ex)
{
tb_show.Text = "提示:未找到该文件，请先创建文件";
}
}</p> <p> private async void btnCopyFile_Click(object sender, RoutedEventArgs e)
{
try
{
StorageFile sf = await storageFolder.GetFileAsync(this.tbFileName.Text.Trim());
StorageFile storageFileCopy = await sf.CopyAsync(KnownFolders.DocumentsLibrary, "copyFile.txt",
NameCollisionOption.ReplaceExisting);
tb_show.Text = "提示:“库文档" + this.tbFileName.Text.Trim() + "”文件拷贝一份到“库文档copyFile.txt”";
}
catch (Exception ex)
{
tb_show.Text = "提示:未找到该文件，请先创建文件";
}
}</p> <p> private async void btnReNameFile_Click(object sender, RoutedEventArgs e)
{
try
{
StorageFile sf = await storageFolder.GetFileAsync(this.tbFileName.Text.Trim());
await sf.RenameAsync("renameFile.txt", NameCollisionOption.ReplaceExisting);
tb_show.Text = "提示:“库文档" + this.tbFileName.Text.Trim() + "”文件重命名为“库文档renameFile.txt”";
}
catch (Exception ex)
{
tb_show.Text = "提示:未找到该文件，请先创建文件";
}
}
最后我们来看文件夹操作读取文件夹/创建文件夹/删除文件夹/重命名文件夹的Cs代码如下：
private async void readFolder_Click(object sender, RoutedEventArgs e)
{
StorageFolder picfolder = KnownFolders.PicturesLibrary;
IReadOnlyList<StorageFile> list = await picfolder.GetFilesAsync();
string picinfo = "图片库文件夹下文件名是：";
foreach (StorageFile item in list)
{
picinfo += item.Name + "+";
}
tb_show.Text = picinfo;
}</p> <p> private async void btnCreateFolder_Click(object sender, RoutedEventArgs e)
{
try
{
StorageFolder picfolder = KnownFolders.PicturesLibrary;
await picfolder.CreateFolderAsync("NewMusic", CreationCollisionOption.ReplaceExisting);
tb_show.Text = "提示:“库图片”文件夹下新建“库图片NewMusic”文件夹";
}
catch (Exception ex)
{
tb_show.Text = "提示:未找到该文件夹，请先创建文件夹";
}
}</p> <p> private async void btnDeleteFolder_Click(object sender, RoutedEventArgs e)
{
try
{
StorageFolder picfolder = KnownFolders.PicturesLibrary;
var newFolder = await picfolder.GetFolderAsync("NewMusic");
await newFolder.DeleteAsync();
tb_show.Text = "提示:“库图片”文件夹下删除“库图片NewMusic”文件夹";
}
catch (Exception ex)
{
tb_show.Text = "提示:未找到该文件夹，请先创建文件夹";
}
}</p> <p> private async void btnReNameFolder_Click(object sender, RoutedEventArgs e)
{
try
{
StorageFolder picfolder = KnownFolders.PicturesLibrary;
var newFolder = await picfolder.GetFolderAsync("NewMusic");
await newFolder.RenameAsync("New Picture");
tb_show.Text = "提示:“库图片”文件夹下重命名“库图片NewMusic”文件夹";
}
catch (Exception ex)
{
tb_show.Text = "提示:未找到该文件夹，请先创建文件夹";
}
}
