C# 让程序自动以管理员身份运行

在程序中加入MANIFEST资源： 

1） 打开Vs2005或vs2008工程，看在Properties下是否有app.manifest这个文件；如没有，右击工程在菜单中选择“属性”，出现界面如下：

选中"Security"，在界面中勾选"Enable ClickOnce Security Settings"后，在Properties下就有自动生成app.manifest文件。

打开app.manifest文件，将

<requestedExecutionLevel  level="asInvoker" uiAccess="false" />

改为

<requestedExecutionLevel level="requireAdministrator" uiAccess="false" />

修改后的app.manifest为：

 
  <? 
  xml version="1.0" encoding="utf-8" 
  ?> 
  
 
  < 
  asmv1:assembly  
  manifestVersion 
  ="1.0" 
   xmlns 
  ="urn:schemas-microsoft-com:asm.v1" 
   xmlns:asmv1 
  ="urn:schemas-microsoft-com:asm.v1" 
   xmlns:asmv2 
  ="urn:schemas-microsoft-com:asm.v2" 
   xmlns:xsi 
  ="http://www.w3.org/2001/XMLSchema-instance" 
  > 
  
   
  < 
  assemblyIdentity  
  version 
  ="1.0.0.0" 
   name 
  ="MyApplication.app" 
    
  /> 
  
   
  < 
  trustInfo  
  xmlns 
  ="urn:schemas-microsoft-com:asm.v2" 
  > 
  
     
  < 
  security 
  > 
  
       
  < 
  requestedPrivileges  
  xmlns 
  ="urn:schemas-microsoft-com:asm.v3" 
  > 
  
         
  <!-- 
   UAC Manifest Options
            If you want to change the Windows User Account Control level replace the 
            requestedExecutionLevel node with one of the following.

        <requestedExecutionLevel  level="asInvoker" uiAccess="false" />
        <requestedExecutionLevel  level="requireAdministrator" uiAccess="false" />
        <requestedExecutionLevel  level="highestAvailable" uiAccess="false" />

            If you want to utilize File and Registry Virtualization for backward 
            compatibility then delete the requestedExecutionLevel node.
         
  --> 
  
         
  < 
  requestedExecutionLevel  
  level 
  ="requireAdministrator" 
   uiAccess 
  ="false" 
    
  /> 
  
       
  </ 
  requestedPrivileges 
  > 
  
       
  < 
  applicationRequestMinimum 
  > 
  
         
  < 
  defaultAssemblyRequest  
  permissionSetReference 
  ="Custom" 
    
  /> 
  
         
  < 
  PermissionSet  
  class 
  ="System.Security.PermissionSet" 
   version 
  ="1" 
   Unrestricted 
  ="true" 
   ID 
  ="Custom" 
   SameSite 
  ="site" 
    
  /> 
  
       
  </ 
  applicationRequestMinimum 
  > 
  
     
  </ 
  security 
  > 
  
   
  </ 
  trustInfo 
  > 
  
 
  </ 
  asmv1:assembly 
  > 
 

 

然后在"Security"中再勾去"Enable ClickOnce Security Settings"后，重新编译即可。
