[C#]建立資料夾範例程式

C#可透過System.IO.Directory.CreateDirectory(dirPath)來建立資料夾
如果dirPath中有不存在的資料夾，CreateDirectory會順便建立此資料夾。
下列範例會在C:\底下建立一個TestDir

using System;
using System.IO;

public class Program
{
    public static void Main()
    {
        string dirPath = @"C:\TestDir";
        if (Directory.Exists(dirPath))
        {
            Console.WriteLine("The directory {0} already exists.", dirPath);
        }
        else
        {
            Directory.CreateDirectory(dirPath);
            Console.WriteLine("The directory {0} was created.", dirPath);
        }
    }
}
