saving a file and automatically create directories

Question

i am concatenating a number of variables and i want to save that string as a file path.

is there a way it will automatically create all appropriate directories if they dont exist without having to check "if exists" on each one

for example . .

"C:\" + a + "\" + b+ "\" + d + "\" + d + ".txt"

Answer 1

Use new FileInfo(path).Directory.Create().

(This creates anything in the hierarchy that's required. If the directory already exists it does nothing.)

Answer 2

using System.IO;
....
Directory.CreateDirectory(@"c:\temp\a\b\c\d\e");
