C# 讓程式自動以管理員身份運行

在程式中加入MANIFEST資源： 

1） 開啟Vs2005或vs2008工程，看在Properties下是否有app.manifest這個檔案；如沒有，右擊工程在菜單中選擇“屬性”，出現介面如下：

選中"Security"，在介面中勾選"Enable ClickOnce Security Settings"後，在Properties下就有自動產生app.manifest檔案。

開啟app.manifest檔案，將

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

改為

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

修改後的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>

 

然後在"Security"中再勾去"Enable ClickOnce Security Settings"後，重新編譯即可。
