.NET调用Windows API隐藏控制台程序运行的窗口，并设置开机自启动

首先编写功能代码类，如下

  
    

   
      1 
   
     using
   
      System;

   
      2 
   
      
   
     using
   
      System.Collections.Generic;

   
      3 
   
      
   
     using
   
      System.Text;

   
      4 
   
     
   
     using
   
      System.Windows.Forms;

   
      5 
   
     
   
     using
   
      Microsoft.Win32;

   
      6 
   
     
   
     using
   
      System.Runtime.InteropServices;

   
      7 
   
     

   
      8 
   
     
   
     ///
   
     

   
      9 
   
     
   
     ///

     10

      Utilities

   
     11 
   
     {

   
     12

     class
   
      windowUtilities

   
     13 
   
      {

   
     14

     15 
   
      
   
     private
   
      
   
     static
   
      
   
     extern
   
      
   
     bool
   
      ShowWindow(IntPtr hWnd, 
   
     uint
   
      nCmdShow);

   
     16 
   
      [DllImport(

     17

     23 
   
      {

   
     24

     //

     void
   
      SetAutoStart()

   
     34 
   
      {

   
     35 
   
      
   
     string
   
      R_startPath 
   
     =
   
      Application.ExecutablePath;

   
     36 
   
      RegistryKey rk_local 
   
     =
   
      Registry.LocalMachine;

   
     37 
   
      RegistryKey rk_run 
   
     =
   
      rk_local.CreateSubKey(
   
     @"

     );

   
     38 
   
      
   
     //
   
     rk_run.DeleteSubKey("ConsoleApp_yh", false);
   
     

   
     39 
   
     
   
      

   
     40 
   
      rk_run.SetValue(

     41 
   
      rk_run.Close();

   
     42 
   
      rk_local.Close();

   
     43 
   
      }

   
     44 
   
      }

   
     45 
   
     }
  
    

调用形式如下：

  
    

   
      1 
   
     using
   
      System;

   
      2 
   
     
   
     using
   
      System.Collections.Generic;

   
      3 
   
     
   
     using
   
      System.Text;
   
     

   
      5 
   
     
   
     using
   
      System.Runtime.InteropServices;

   
      6 
   
     
   
     using
   
      System.IO;

   
      7 
   
     

   
      8 
   
     

   
      9 
   
     

   
     10 
   
     
   
     namespace
   
      Test

   
     11 
   
     {

   
     12 
   
      
   
     class
   
      Program

   
     13 
   
      {

   
     14 
   
      

   
     15 
   
      

   
     16 
   
      
   
     static
   
      
   
     void
   
      Main(
   
     string
   
     [] args)

   
     17 
   
      {

   
     18 
   
      Console.Title 
   
     =
   
      
   
     "
   
     tohidewindow
   
     "
   
     ; 
   
     //
   
     为控制台窗体指定一个标题，便于定位和区分
   
     

   
     19 
   
     
   
      Utilities.windowUtilities.WindowHide(
   
     "
   
     tohidewindow
   
     "
   
     );

   
     20 
   
      
   
     //
   
     隐藏这个窗口
   
     

   
     21 
   
     
   
      Utilities.windowUtilities.SetAutoStart();
   
     //
   
     设置开机自启动
   
     

   
     22 
   
     
   
      Console.ReadKey();

   
     23 
   
      }

   
     24 
   
      }

   
     25 
   
     } 
  
    

 说明：在设置开机自启动还是有一点问题，前提是用户必须具有管理员权限，不然操作不了注册表。
