Create folder windows-like

See more:

C#

So i'm working on a FileExplorer Type thing in C# with more functionalities like renaming a bunch of files/folders, and i'm also providing the Basic Copy/Paste/Cut operations.

Now i'm working on the create new folder button And i want it to be windows-like

My code so far :

int i = 0;
while (true)
 {
   string dirName = i == 0 ? System.IO.Path.Combine(txtCurrentPath.Text, "New Folder") : System.IO.Path.Combine(txtCurrentPath.Text, "New Folder (" + i + ")");
   if (!Directory.Exists(dirName))
    {
     Directory.CreateDirectory(dirName);
     break;
    }
      else
         i++;
}

Anyway my question is, How can i avoid all of that and just send a simple command or something like that to the explorer to use the built-in way of creating new folder.
i'm new to all this windows api and shell extension stuff, Thanks :)

What I have tried:

i googled and all that pops up is the C# way Directory.CreateDirectory(String DirName);
