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:复制代码代码如下:<Grid Background="{StaticResource ApplicationPageBackgroundThemeBrush}"> <!--显示区--> <TextBlock HorizontalAlignment="Left" Margin=",,0,0" TextWrapping="Wrap" Text="文件名:" VerticalAlignment="Top" Height="" Width=""/> <TextBox HorizontalAlignment="Left" Margin=",,0,0" TextWrapping="Wrap" Text="test.txt" VerticalAlignment="Top" Width="" Name="tbFileName"/> <TextBox HorizontalAlignment="Left" Margin=",,0,0" TextWrapping="Wrap" Text="默认需要添加的文件内容" VerticalAlignment="Top" Width="" Name="tbContent"/> <TextBlock HorizontalAlignment="Left" Margin=",,0,0" TextWrapping="Wrap" Text="文件内容:" VerticalAlignment="Top" Height="" Width=""/> <TextBlock HorizontalAlignment="Left" Margin=",,0,0" TextWrapping="Wrap" Text="提示:" VerticalAlignment="Top" Height="" Width="" Name="tb_show"/> <!--删除文件 移动文件 复制文件 重命名文件--> <Button Content="创建并写入文件" HorizontalAlignment="Left" Margin=",,0,0" Name="btnCreateFile" VerticalAlignment="Top" Click="btnCreateFile_Click"/> <Button Content="读取string文件" HorizontalAlignment="Left" Margin=",,0,0" x:Name="btnReadFile" VerticalAlignment="Top" Click="btnReadFile_Click"/> <Button Content="删除文件" HorizontalAlignment="Left" Margin=",,0,0" x:Name="btnDeleteFile" VerticalAlignment="Top" Click="btnDeleteFile_Click"/> <Button Content="移动文件" HorizontalAlignment="Left" Margin=",,0,0" x:Name="btnMoveFile" VerticalAlignment="Top" Click="btnMoveFile_Click"/> <Button Content="复制文件" HorizontalAlignment="Left" Margin=",,0,0" x:Name="btnCopyFile" VerticalAlignment="Top" Click="btnCopyFile_Click"/> <Button Content="重命名文件" HorizontalAlignment="Left" Margin=",,0,0" x:Name="btnReNameFile" VerticalAlignment="Top" Click="btnReNameFile_Click"/> <!--读取文件夹 创建文件夹 删除文件夹 重命名文件夹--> <Button Content="读取文件夹" HorizontalAlignment="Left" Margin=",,0,0" VerticalAlignment="Top" Name="readFolder" Click="readFolder_Click"/> <Button Content="创建文件夹" HorizontalAlignment="Left" Margin=",,0,0" VerticalAlignment="Top" x:Name="btnCreateFolder" Click="btnCreateFolder_Click"/> <Button Content="删除文件夹" HorizontalAlignment="Left" Margin=",,0,0" VerticalAlignment="Top" x:Name="btnDeleteFolder" Click="btnDeleteFolder_Click"/> <Button Content="重命名文件夹" HorizontalAlignment="Left" Margin=",,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:复制代码代码如下: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:复制代码代码如下: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"; } } 最后如需源码请点击 Win8File2_gimoonet.rar 下载
