I have to create multiple text files.

If the already exists I need to add count after the filename.

Example

If I Enter test.txt

If file exists then it should rename as test(1).txt.

If I again give test.txt it should rename as test(2).txt.

How to do this using C#

Solution 1

Create the filename with

C#

string filename = System.IO.Path.Combine(folder, string.Format("Test({0}).txt", i));

and check for its existence with

C#

System.IO.File.Exists(filename);

till that returns false.
