IsolatedStorageFile.DeleteFile Method

Deletes a file in the isolated store.

Namespace:  System.IO.IsolatedStorage
Assembly:  mscorlib (in mscorlib.dll)

public void DeleteFile(
	string file
)

Parameters

file
Type: System.String
The relative path of the file to delete within the isolated store.

ExceptionCondition
IsolatedStorageException

The store has been removed.

Unable to delete the file.

Isolated storage is disabled.

ArgumentException

file is badly formed.

ArgumentNullException

file is null.

ObjectDisposedException

The store has been disposed.

The deleted file cannot be recovered once deleted.

NoteNote:

File deletions are subject to intermittent failures because files can be in use simultaneously by operating system features such as virus scanners and file indexers. This is especially true for recently created files.

For these reasons, it is important to add code to the code block that handles the IsolatedStorageException to retry deleting the file or log a failure.

The following example deletes a file from the store. This example is part of a larger example provided for IsolatedStorageFile class.


// Delete a file.
try
{
    if (store.FileExists(filePath))
    {
        store.DeleteFile(filePath);
    }
}
catch (IsolatedStorageException ex)
{
    sb.AppendLine(ex.Message);
}
