	string searchPattern
)
public String[] GetFileNames (

) : String[]

Parameters

searchPattern

A search pattern. Both single-character ("?") and multi-character ("*") wildcards are supported.

Return Value

An Array of relative paths of files in the isolated storage scope that match searchPattern. A zero-length array specifies that there are no files that match.

The searchPattern was a null reference (Nothing in Visual Basic).

The searchPattern "Project\Data*.txt" will give all ".txt" files beginning with Data in the Project directory of the isolated storage scope. For complete description of search pattern strings, see System.IO.Directory.

For information about how to find directory names, see the GetDirectoryNames method.

The Finding Existing Files and Directories example demonstrates the use of the GetFileNames method.

The following code example demonstrates the GetFileNames method. For the complete context of this example, see the IsolatedStorageFile overview.

    String[] dirNames = isoFile.GetDirectoryNames("*");
    String[] fileNames = isoFile.GetFileNames("Archive\\*");

    // Delete all the files currently in the Archive directory.

    if (fileNames.Length > 0)
    {
        for (int i = 0; i < fileNames.Length; ++i)
        {
            // Delete the files.
            isoFile.DeleteFile("Archive\\" + fileNames[i]);
        }
        // Confirm that no files remain.
        fileNames = isoFile.GetFileNames("Archive\\*");
    }


    if (dirNames.Length > 0)
    {
        for (int i = 0; i < dirNames.Length; ++i)
        {
            // Delete the Archive directory.
        }
    }
    dirNames = isoFile.GetDirectoryNames("*");
    isoFile.Remove();
}
catch (Exception e)
{
    Console.WriteLine(e.ToString());
