			    PathTooLongException
		    
		    The path exceeds the system-defined maximum length.

		
		
		    
			    NotSupportedException

  Examples
    	This example searches the directory C:\TestDir for any files containing the string "sample string" and displays the results in ListBox1.
Dim list As System.Collections.ObjectModel.
  ReadOnlyCollection(Of String)
list = My.Computer.FileSystem.FindInFiles("C:\TestDir", 
 "sample string", True, FileIO.SearchOption.SearchTopLevelOnly)
For Each name In list
    ListBox1.Items.Add(name)
Next

In order to work, the project must contain a ListBox named ListBox1.


    	Remarks
    	An empty collection is returned if no files matching the specified pattern are found.
