C Method for Automatic Generation of New Files with Duplicate Names When Saving Files

In this paper, the method of automatically generating new files with duplicate names when saving files is described by C #. Share it for your reference. The details are as follows:

When you save a document as a. txt and find that the file already exists, automatically save it as a (1). txt

/// <summary>
/// Generates a new path for duplicate filenames.
/// </summary>
/// <param name="path">The path.</param>
/// <returns></returns>
private string GetNewPathForDupes( string path )
{
  string directory = Path.GetDirectoryName( path );
  string filename = Path.GetFileNameWithoutExtension( path );
  string extension = Path.GetExtension( path );
  int counter = 1;
  string newFullPath;
  do
  {
  string newFilename = "{0}({1}).{2}".FormatWith( filename, counter, extension );
  newFullPath = Path.Combine( directory, newFilename );
  counter++;
  } while ( System.IO.File.Exists( newFullPath ) );
  return newFullPath;
}

I hope this article is helpful to everyone's C # programming.
