实现管理员身份运行软件

针对WPF软件启动使用代码控制以管理员身份运行：

1、app.manifest配置文件

修改UAC 清单选项中requestedExecutionLevel 节点，将会禁用文件和注册表虚拟化。

<trustInfo xmlns="urn:schemas-microsoft-com:asm.v2">
    <security>
      <requestedPrivileges xmlns="urn:schemas-microsoft-com:asm.v3">

        <requestedExecutionLevel level="requireAdministrator" uiAccess="false" />
      </requestedPrivileges>
      <applicationRequestMinimum>
        <defaultAssemblyRequest permissionSetReference="Custom" />
        <PermissionSet class="System.Security.PermissionSet" version="1" ID="Custom" SameSite="site" Unrestricted="true" />
      </applicationRequestMinimum>
    </security>
  </trustInfo>

2、c#代码控制

此处c#代码转载与http://blog.csdn.net/cleopard/article/details/40583595。重写OnStartup方法。

protected override void OnStartup(StartupEventArgs e)  
      {  
          base.OnStartup(e);  
  
          CheckAdministrator();  
          //如果不是管理员，程序会直接退出，并使用管理员身份重新运行。  
          StartupUri = new Uri("MainWindow.xaml", UriKind.RelativeOrAbsolute);  
      }

 private void CheckAdministrator()
        {
            var wi = WindowsIdentity.GetCurrent();
            var wp = new WindowsPrincipal(wi);

            bool runAsAdmin = wp.IsInRole(WindowsBuiltInRole.Administrator);

            if (!runAsAdmin)
            {
                // It is not possible to launch a ClickOnce app as administrator directly,
                // so instead we launch the app as administrator in a new process.
                var processInfo = new ProcessStartInfo(Assembly.GetExecutingAssembly().CodeBase);

                // The following properties run the new process as administrator
                processInfo.UseShellExecute = true;
                processInfo.Verb = "runas";

                // Start the new process
                try
                {
                    Process.Start(processInfo);
                }
                catch (Exception ex)
                {
                    //ex.WriteLog();
                }

                // Shut down the current process
                Environment.Exit(0);
            }
        }
