文件以及文件夾操作
在本文中我們將學習win 8中的文件以及文件夾的各種操作。
在本文中文件操作主要是講述：刪 除文件/移動文件/復制文件/重命名文件
文件夾操作分為：讀取文件夾/創建文件夾/刪除文件夾/重 命名文件夾
首先貼出所有的Xaml代碼文件部分：
<Grid Background="{StaticResource
ApplicationPageBackgroundThemeBrush}">
<!--顯示區-->
<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="默認需要添加的文件內容" VerticalAlignment="Top" Width="431" Name="tbContent"/>
<TextBlock HorizontalAlignment="Left" Margin="396,42,0,0" TextWrapping="Wrap" Text="文件內容："
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"/>
<!--刪除文件 移動文件 復制文件 重命名文件-->
<Button Content="創建並寫入文件" HorizontalAlignment="Left" Margin="127,99,0,0"
Name="btnCreateFile" VerticalAlignment="Top" Click="btnCreateFile_Click"/>
<Button Content="讀取string文件" HorizontalAlignment="Left" Margin="757,99,0,0"
x:Name="btnReadFile" VerticalAlignment="Top" Click="btnReadFile_Click"/>
<Button Content="刪除文件" HorizontalAlignment="Left" Margin="127,223,0,0"
x:Name="btnDeleteFile" VerticalAlignment="Top" Click="btnDeleteFile_Click"/>
<Button Content="移動文件" HorizontalAlignment="Left" Margin="320,223,0,0"
x:Name="btnMoveFile" VerticalAlignment="Top" Click="btnMoveFile_Click"/>
<Button Content="復制文件" 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"/>
<!--讀取文件夾 創建文件夾 刪除文件夾 重命名文件夾-->
<Button Content="讀取文件夾" HorizontalAlignment="Left" Margin="127,296,0,0"
VerticalAlignment="Top" Name="readFolder" Click="readFolder_Click"/>
<Button Content="創建文件夾" HorizontalAlignment="Left" Margin="305,296,0,0"
VerticalAlignment="Top" x:Name="btnCreateFolder" Click="btnCreateFolder_Click"/>
<Button Content="刪除文件夾" HorizontalAlignment="Left" Margin="545,296,0,0"
VerticalAlignment="Top" x:Name="btnDeleteFolder" Click="btnDeleteFolder_Click"/>
<Button Content="重命名文件夾" HorizontalAlignment="Left" Margin="766,296,0,0"
VerticalAlignment="Top" x:Name="btnReNameFolder" Click="btnReNameFolder_Click"/>
</Grid>
其次我們來看刪除文件/移動文件/復制文件/重命名文件的Cs代碼：
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() + "文件刪除成功!";
}
catch (Exception ex)
{
tb_show.Text = "提示:未找到該文件，請先創建文件";
}
}
private async void btnMoveFile_Click(object sender, RoutedEventArgs e)
{
try
{
//將文件從文檔移動到音樂庫
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:“庫\\文檔\\" + this.tbFileName.Text.Trim() + "”文件移動到“庫\\音樂\\moveFile.txt”";
}
catch (Exception ex)
{
tb_show.Text = "提示:未找到該文件，請先創建文件";
}
}
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:“庫\\文檔\\" + this.tbFileName.Text.Trim() + "”文件拷貝一份到“庫\\文檔\\copyFile.txt”";
}
catch (Exception ex)
{
tb_show.Text = "提示:未找到該文件，請先創建文件 ";
}
}
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:“庫\\文檔\\" + this.tbFileName.Text.Trim() + "”文件重命名為“庫\\文檔\\renameFile.txt”";
}
catch (Exception ex)
{
tb_show.Text = "提示:未找到該文件，請先創建文件";
}
}
最後我們來看文件夾操作讀取文件夾/創建文件夾/刪除文件夾/重命名文件夾的Cs代碼如下：
private async void readFolder_Click(object sender, RoutedEventArgs e)
{
StorageFolder picfolder = KnownFolders.PicturesLibrary;
IReadOnlyList<StorageFile> list = await picfolder.GetFilesAsync();
string picinfo = "圖片庫文件夾下文件名是：";
foreach (StorageFile item in list)
{
picinfo += item.Name + "+";
}
tb_show.Text = picinfo;
}
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:“庫\\圖片\\”文件夾下新建“庫\\圖片\\NewMusic”文件夾";
}
catch (Exception ex)
{
tb_show.Text = "提示:未找到該文件夾，請先創建文件夾";
}
}
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:“庫\\圖片\\”文件夾下刪除“庫\\圖片\\NewMusic”文件夾";
}
catch (Exception ex)
{
tb_show.Text = "提示:未找到該文件夾，請先創建文件夾;
}
}
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:“庫\\圖片\\”文件夾下重命名“庫\\圖片\\NewMusic”文件夾";
}
catch (Exception ex)
{
tb_show.Text = "提示:未找到該文件夾，請先創建文件夾";
}
}
