Can you post the code, there probably is something in it that should be changed.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            FileInfo file1 = new FileInfo(@"C:\Text12341234");
            file1.CreateText();
            Console.WriteLine("Created.");
            file1.Delete();
            Console.WriteLine("Deleted.");
        }
    }
}

and at:
file1.Delete();
it says that it already use by another procces.
please help

Try "file1.Close();" before deleting.

"FileInfo does not contain a definition for 'Close' and no extension method 'Close' accepting a first argument of type FileInfo could be found (are you missing a using directive or an assembly reference?)"
I can't use Close() for FileInfo.. please help

Oh, didn't notice it was of type FileInfo... Anyway, try this, I think it would work:

FileInfo file1 = new FileInfo (@"C:\Text12341234");
StreamWriter sw = file1.CreateText ();
Console.WriteLine ("Created.");

sw.Close ();
file1.Delete ();
Console.WriteLine ("Deleted.");

The method "CreateText" opens the file, preparing it for writing, and returns a StreamWriter, which can be used to write contents to the file. If you don't close it through StreamWriter, then the file will be marked as still in use.

yeh thats what i did.
working now..
1 more thing, how can i change the name of a file?

[doqunbop]

file1.MoveTo ("C:/ANewName.txt");

Just make sure the file isn't open for writing or is closed before attempting to "move" it. (Moving the file can be understood as moving the contents to a new file)
