C# 让程序自动以管理员身份运行，请求权限【转】
exe在Vista或Win7下不以管理员权限运行，会被UAC（用户帐户控制）阻止访问系统某些功能，如修改注册表操作等；如何让exe以管理员权限运行呢，方法有两种，一个是直接修改exe属性；另一个是在程序中加入MANIFEST资源，下面分别介绍。
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：
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>
<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。
