1、直接修改exe屬性
1) 右擊“exe”，在彈出的菜單中選擇“屬性”，出現的界面如下圖：
2) 選擇"Compatibility"項，並勾選"Run this program as administrator"項即可。
2、 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”，出現界面如下圖：
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

<

<!--
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，重新編譯即可。
