Vista 和 Windows 7 操作系统为了加强安全，增加了 UAC(用户账户控制) 的机制，如果 UAC 被打开，用户即使是以管理员权限登录，其应用程序默认情况下也无法对系统目录，系统注册表等可能影响系统运行的设置进行写操作。这个机制大大增强了系统的安全性，但对应用程序开发者来说，我们不能强迫用户去关闭UAC，但有时我们开发的应用程序又需要以 Administrator 的方式运行，即 Win7 中 以 as administrator 方式运行，那么我们怎么来实现这样的功能呢？
我们在 win7 下运行一些安装程序时，会发现首先弹出一个对话框，让用户确认是否同意允许这个程序改变你的计算机配置，但我们编写的应用程序默认是不会弹出这个提示的，也无法以管理员权限运行。本文介绍了 C# 程序如何设置来提示用户以管理员权限运行。
首先在项目中增加一个 Application Manifest File
默认的配置如下：
<?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="asInvoker" uiAccess="false" />
</requestedPrivileges>
</security>
</trustInfo>
</asmv1:assembly>
<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

-->
<requestedExecutionLevel level="asInvoker" uiAccess="false" />
</requestedPrivileges>
</security>
</trustInfo>
</asmv1:assembly>
我们可以看到这个配置中有一个 requestedExecutionLevel 项，这个项用于配置当前应用请求的执行权限级别。这个项有3个值可供选择，如下表所示：
| Value | Description | Comment |
| asInvoker | The application runs with the same access token as the parent process. | Recommended for standard user applications. Do refractoring with internal elevation points, as per the guidance provided earlier in this document. |
| highestAvailable | The application runs with the highest privileges the current user can obtain. | Recommended for mixed-mode applications. Plan to refractor the application in a future release. |
| requireAdministrator | The application runs only for administrators and requires that the application be launched with the full access token of an administrator. | Recommended for administrator only applications. Internal elevation points are not needed. The application is already running elevated. |
