How to create a Sub Folder into an existing folder?

Question

When my Windows Form Loads it run the following code Directory.CreateDirectory(Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments), "F.U.T.U.R.E")); Which therefor create a folder with the name "F.U.T.U.R.E" Inside MyDocuments Directory. Now I would like to create another Folder when I press on a button inside the existing folder "F.U.T.U.R.E" .

private void button1_Click(object sender, EventArgs e)
{
  // Create Sub Folder into My.Documents."F.U.T.U.R.E"
}

Can anyone help me with the codes.

Well, one way is to use the DirectoryInfo that gets returned from that original CreateDirectory call, and use the CreateSubdirectory method on it to do as needed.

https://msdn.microsoft.com/en-us/library/system.io.directoryinfo(v=vs.110).aspx

So:

var directoryInfo = Directory.CreateDirectory(Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments), "F.U.T.U.R.E"));

directoryInfo.CreateSubdirectory("MySubFolder");

However, there are a fair few ways to achieve this so don't take this as the defacto way to do it. Personally I never even realised the CreateSubdirectory method even existed, I've always done it by building the URLs and calling the CreateDirectory method. Learn something new everyday :-)
