Hi All,

Problem: I have a multiple files. These files displayed by using listbox. When select any one of the file from listbox it should be copied into another file and I don't want the full content of file I want only some part of a file copied into another file. I think this can be done through the memory stream.

I wrote this much of code
string sourceFile = listBox1.SelectedItem.ToString();
            
 string destinationFile = @"D:\Sowjanya\Directx files\Hero.X";
            try
            {
                //causes exception if already exists.
                File.Delete(destinationFile);
                string str1="animationset";
                if(sourceFile.Contains(str1))
                File.Copy(sourceFile, destinationFile);
                MessageBox.Show("Copy completed.");
            }

            catch (Exception e1)
            {
                Console.WriteLine(e1.Message);
            }
            Console.Read();

It was copied whole content of file ... but I want some part text only
i.e if the file contains the animationset method that whole method must be copied into antoher file. That selected file is must be having an animationset method like this
animatinset
{
.......
}

This is what I want

Please help me.

Well, you DID call File.Copy. Yo don't need a memory stream. You need File.ReadAlllines or File.ReadAllBytes to read the whole file in memory, then you need to parse the file to find the bits you want to copy, then you can use a similar overload to write the new file fragment.
