我实现了一些代码来手动完成:

using System.Security.Principal;
public bool IsUserAdministrator()
{
    bool isAdmin;
    try
    {
        WindowsIdentity user = WindowsIdentity.GetCurrent();
        WindowsPrincipal principal = new WindowsPrincipal(user);
        isAdmin = principal.IsInRole(WindowsBuiltInRole.Administrator);
    }
    catch (UnauthorizedAccessException ex)
    {
        isAdmin = false;
    }
    catch (Exception ex)
    {
        isAdmin = false;
    }
    return isAdmin;
}

您可以使用ClickOnce Security Settings创建清单，然后禁用它:

Right click on the Project -> Properties -> Security -> Enable ClickOnce Security Settings

单击后，将在项目的属性文件夹下创建一个名为app.manifest的文件，一旦创建，您可以取消选中启用ClickOnce安全设置选项

打开该文件并更改这一行:

<requestedExecutionLevel level="asInvoker" uiAccess="false" />

to:

 <requestedExecutionLevel  level="requireAdministrator" uiAccess="false" />

这将使程序需要管理员权限。

具体步骤如下。

将应用程序清单文件添加到项目 更改应用程序设置为"app.manifest" 更新标签“requestedExecutionLevel”为requireAdministrator。

注意，使用这段代码你需要关闭ClickOnce的安全设置，为此，进入Properties -> security -> ClickOnce security

如果出于某种原因需要纯代码解决方案，这里有一个独立的类文件。只需在应用程序启动时调用“AdminRelauncher.RelaunchIfNotAdmin()”:

using System;
using System.Diagnostics;
using System.Reflection;
using System.Security.Principal;

public static class AdminRelauncher
{
    public static void RelaunchIfNotAdmin()
    {
        if (!RunningAsAdmin())
        {
            Console.WriteLine("Running as admin required!");
            ProcessStartInfo proc = new ProcessStartInfo();
            proc.UseShellExecute = true;
            proc.WorkingDirectory = Environment.CurrentDirectory;
            proc.FileName = Assembly.GetEntryAssembly().CodeBase;
            proc.Verb = "runas";
            try
            {
                Process.Start(proc);
                Environment.Exit(0);
            }
            catch (Exception ex)
            {
                Console.WriteLine("This program must be run as an administrator! \n\n" + ex.ToString());
                Environment.Exit(0);
            }
        }
    }

    private static bool RunningAsAdmin() 
    {
        WindowsIdentity id = WindowsIdentity.GetCurrent();
        WindowsPrincipal principal = new WindowsPrincipal(id);

        return principal.IsInRole(WindowsBuiltInRole.Administrator);
    }
}

我实现了一些代码来手动完成:

using System.Security.Principal;
public bool IsUserAdministrator()
{
    bool isAdmin;
    try
    {
        WindowsIdentity user = WindowsIdentity.GetCurrent();
        WindowsPrincipal principal = new WindowsPrincipal(user);
        isAdmin = principal.IsInRole(WindowsBuiltInRole.Administrator);
    }
    catch (UnauthorizedAccessException ex)
    {
        isAdmin = false;
    }
    catch (Exception ex)
    {
        isAdmin = false;
    }
    return isAdmin;
}

在Visual Studio 2008上工作时，右键单击项目->添加新项，然后选择应用程序清单文件。

在清单文件中，你会发现标签requestedExecutionLevel，你可以将级别设置为三个值:

<requestExecutionLevel level=“asInvoker” uiAccess=“false” />

OR

< requestdexecutionlevel level="requireAdministrator" uiAccess="false" />

OR

<requestExecutionLevel level=“highestAvailable” uiAccess=“false” />

要将应用程序设置为以管理员身份运行，必须选择中间的一个。
