IsolatedStorageFile.DeleteFile Method

public void DeleteFile(
	string file
)

Isolated storage is disabled.

file is badly formed.

ArgumentNullException

file is null.

ObjectDisposedException

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. Macintosh users should be aware of this issue because of its frequent indexing.

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);
}
