Question

I think that all i need is in the question. I placed my method in my Form.Load I can either create a folder or open a SaveFileDialog but not both at once.

If someone could help me please.
Thanks.

SaveFileDialog lets the user choose a file location that already exists. If not, they can create a folder within the dialog as @Bali suggested.

If you want the user to be able to create a new folder without using the dialog then you’ll need to let the user type the path (e.g. in a textbox). Then you can check to see if the directory exist using Directory.Exist, and if not, create it using Directory.Create.

void CheckPath(string path)
{
   var dir = Path.GetDirectoryName(path);
   if( !String.IsNullOrEmpty(dir) && !Directory.Exists(dir))
      Directory.Create(dir);
}
