获取系统基本信息

　　本文将使用C#来获取系统的基本信息。

　　结果如图所示：

　　为了获取系统信息，我将调用windows自带的kernel32.dll程序。代码如下所示：

 

  1 using System;
  2 using System.Collections.Generic;
  3 using System.ComponentModel;
  4 using System.Data;
  5 using System.Drawing;
  6 using System.Linq;
  7 using System.Text;
  8 using System.Windows.Forms;
  9 using System.Runtime.InteropServices;

 15     public partial class Form1 : Form
 16     {
 17         public Form1()
 18         {
 19             InitializeComponent();
 20         }
 21

 23         public static extern void GetWindowsDirectory(StringBuilder WinDir, int count);
