Getting Started with Windows 8 Development (13) file and folder management for Windows 8 2

File and folder actions

In this article we will learn about the files in Win 8 and the various actions of the folders.

File actions in this article are mainly about: deleting files/moving files/copying files/renaming files

Folder operation is divided into: Read folder/Create Folder/delete Folder/Rename folder

First, all of the XAML code file sections are posted:

<grid background= "{StaticResource Applicationpagebackgroundthemebrush}" > <!--display area--> <tex Tblock horizontalalignment= "left" margin= "137,42,0,0 textwrapping=" Wrap "text=" FileName: "VerticalAlignment
                 = "Top" height= "width="/> <textbox horizontalalignment= "left" margin= "185,33,0,0" textwrapping= "Wrap" text= "Test.txt" verticalalignment= "Top" width= "121" name= "Tbfilename"/> <textbox Horizontal Alignment= "left" margin= "457,33,0,0" textwrapping= "Wrap" text= "The contents of the file to be added by default" verticalalignment= "Top" Width = "431" name= "tbcontent"/> <textblock horizontalalignment= "left" margin= "396,42,0,0" textwrapping= "Wrap" Text = "File content:" verticalalignment= "Top" height= "width="/> <textblock horizontalalignment= "Left" margin= "127,163,0,0" textwrapping= "Wrap" text= "Hint:" verticalalignment= "Top" height= "" width= "7

    Rgin= "766,296,0,0" verticalalignment= "Top" x:name= "Btnrenamefolder" click= "Btnrenamefolder_click"/> </Grid>

Second, let's take a look at the CS code for deleting files/moving files/copying files/renaming files:

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 = "Hint:" + this.tbFileName.Text.Trim () + "file Delete successful!";
}
catch (Exception ex)
{
Tb_show. Text = "Hint: The file was not found, please create the file first";
}
}
Private async void Btnmovefile_click (object sender, RoutedEventArgs e)
{
Try
{
Move a file from a document to a music library
Storagefile SF = await Storagefolder.getfileasync (This.tbFileName.Text.Trim ());
Storagefolder NewFolder = knownfolders.musiclibrary;
Await SF. Moveasync (NewFolder, "MoveFile.txt", namecollisionoption.replaceexisting);
Tb_show. Text = "Hint: library \ \ document \ \" + This.tbFileName.Text.Trim () + "" file moved to library \ Music \\moveFile.txt "";
}
catch (Exception ex)
{
Tb_show. Text = "Hint: The file was not found, please create the file first";
}
}
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 = "Hint: library \ \ document \ \" + This.tbFileName.Text.Trim () + "" File copy to "library \ Document \\copyFile.txt";
}
catch (Exception ex)
{
Tb_show. Text = "Hint: The file was not found, please create the file first";
}
}
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 = "Hint: library \ \ document \ \" + This.tbFileName.Text.Trim () + "" file renamed to library \ Document \\renameFile.txt "";
}
catch (Exception ex)
{
Tb_show. Text = "Hint: The file was not found, please create the file first";
}
}
