自從Vista推出UAC之后，遇到程序需要執行一些高安全級別的操作的時候就需要系統管理員權限，如何讓自己寫的程序能夠自動向系統申請管理員執行權限，也就是在程序的圖標上出現一個小盾牌的圖標呢，使用Visual Studio 2010可以很方便的做到這一點。具體步驟如下：

1、在項目中增加一個Application Manifest File

2、打開新增加的app.manifest文件，文件的內容如下：

app.mainfest<?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"?/>

????????????Specifying?requestedExecutionLevel?node?will?disable?file?and?registry?virtualization.
????????????If?you?want?to?utilize?File?and?Registry?Virtualization?for?backward?
????????????compatibility?then?delete?the?requestedExecutionLevel?node.
????????-->
????????<requestedExecutionLevel?level="requireAdministrator"?uiAccess="false"?/>
??????</requestedPrivileges>
????</security>
??</trustInfo>
??
??<compatibility?xmlns="urn:schemas-microsoft-com:compatibility.v1">
????<application>
??????<!--?A?list?of?all?Windows?versions?that?this?application?is?designed?to?work?with.?Windows?will?automatically?select?the?most?compatible?environment.-->

??????<!--?If?your?application?is?designed?to?work?with?Windows?7,?uncomment?the?following?supportedOS?node-->
??????<!--<supportedOS?Id="{35138b9a-5d96-4fbd-8e2d-a2440225f93a}"/>-->
??????
????</application>
??</compatibility>
??
??<!--?Enable?themes?for?Windows?common?controls?and?dialogs?(Windows?XP?and?later)?-->
??<!--?<dependency>
????<dependentAssembly>
??????<assemblyIdentity
??????????type="win32"
??????????name="Microsoft.Windows.Common-Controls"
??????????version="6.0.0.0"
??????????processorArchitecture="*"
??????????publicKeyToken="6595b64144ccf1df"
??????????language="*"
????????/>
????</dependentAssembly>
??</dependency>-->

</asmv1:assembly>

3、把<requestedPrivileges〉節中的配置項<requestedExecutionLevel level=" asInvoker" uiAccess="false" />改為<requestedExecutionLevel level=" requireAdministrator " uiAccess="false" />

4、重新編譯程序，編譯好后的程序圖標上就會出現一個小盾牌，就可以以管理員身份啟動了。
