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

xmlns:xsi

>
<
assemblyIdentity

/>
<
trustInfo
xmlns

<
security

<

<!--
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.

<

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