怎样在磁盘上建一个文件夹?

来自在.netframework文档：

示例 [Visual Basic, C#, C++] 下面的示例创建并删除指定目录。 [Visual Basic] Imports System Imports System.IO Imports Microsoft.VisualBasic

Public Class Test Public Shared Sub Main() ' Specify the directory you want to manipulate. Dim path As String = "c:\MyDir"

Try ' Determine whether the directory exists. If Directory.Exists(path) Then Console.WriteLine("That path exists already.") Return End If

' Try to create the directory. Dim di As DirectoryInfo = Directory.CreateDirectory(path) Console.WriteLine("The directory was created successfully at {0}.", Directory.GetCreationTime(path))

' Delete the directory. di.Delete() Console.WriteLine("The directory was deleted successfully.")

Catch e As Exception Console.WriteLine("The process failed: {0}.", e.ToString()) End Try End Sub End Class

[C#] using System; using System.IO;

class Test { public static void Main() { // Specify the directory you want to manipulate. string path = @"c:\MyDir";

try { // Determine whether the directory exists. if (Directory.Exists(path)) { Console.WriteLine("That path exists already."); return; }

// Try to create the directory. DirectoryInfo di = Directory.CreateDirectory(path); Console.WriteLine("The directory was created successfully at {0}.", Directory.GetCreationTime(path));

// Delete the directory. di.Delete(); Console.WriteLine("The directory was deleted successfully."); } catch (Exception e) { Console.WriteLine("The process failed: {0}", e.ToString()); } finally {} } }
