C# 讓程序自動以管理員身份運行

在程序中加入MANIFEST資源： 

1） 打開Vs2005或vs2008工程，看在Properties下是否有app.manifest這個文件；如沒有，右擊工程在菜單中選擇“屬性”，出現界面如下：

選中"Security"，在界面中勾選"Enable ClickOnce Security Settings"后，在Properties下就有自動生成app.manifest文件。

打開app.manifest文件，將

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

改為

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

修改后的app.manifest為：

 
          <? 
          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，重新編譯即可。
