1、直接修改exe属性
1) 右击“exe”，在弹出的菜单中选择“属性”，出现的界面如下图：
2) 选择"Compatibility"项，并勾选"Run this program as administrator"项即可。
2、 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”，出现界面如下图：
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。
