WPF 应用程序 - 在运行时请求管理员权限

Question

我的 WPF 应用程序中只有几个选项需要管理员权限。我想避免强制以管理员身份运行程序，所以有没有机会在运行时要求管理员权限，只有在需要此权限的操作的情况下？

Answer 1

我认为您无法提升现有流程。但是我在 powershell 5 中找到了一种在新的提升进程中启动我的脚本的方法。希望这会有所帮助

# Get the ID and security principal of the current user account
$myWindowsID = [System.Security.Principal.WindowsIdentity]::GetCurrent();
$myWindowsPrincipal = New-Object System.Security.Principal.WindowsPrincipal($myWindowsID);

# Get the security principal for the administrator role
$adminRole = [System.Security.Principal.WindowsBuiltInRole]::Administrator;

# Check to see if we are currently running as an administrator
if ($myWindowsPrincipal.IsInRole($adminRole))
{
    # We are running as an administrator, so change the title and background colour to indicate this
    $Host.UI.RawUI.WindowTitle = $myInvocation.MyCommand.Definition + "(Elevated)";
    $Host.UI.RawUI.BackgroundColor = "DarkBlue";
    Clear-Host;
}
else
{
    # We are not running as an administrator, so relaunch as administrator

    # Create a new process object that starts PowerShell
    $newProcess = New-Object System.Diagnostics.ProcessStartInfo "PowerShell";

    # Specify the current script path and name as a parameter with added scope and support for scripts with spaces in it's path
    $newProcess.Arguments = "& '" + $script:MyInvocation.MyCommand.Path + "'"

    # Indicate that the process should be elevated
    $newProcess.Verb = "runas";

    # Start the new process
    [System.Diagnostics.Process]::Start($newProcess);

    # Exit from the current, unelevated, process
    Exit;
}

您可以将应用程序清单文件（app.manifest）添加到您的项目中
并将 requestedExecutionLevel 设置为 highestAvailable"/>

<?xml version="1.0" encoding="utf-8"?>
<assembly manifestVersion="1.0" xmlns="urn:schemas-microsoft-com:asm.v1">
  <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="highestAvailable" uiAccess="false" />

        <!-- requestedExecutionLevel  level="asInvoker" uiAccess="false" /-->
        <!-- requestedExecutionLevel  level="requireAdministrator" uiAccess="false" /-->

      </requestedPrivileges>
    </security>
  </trustInfo>
</assembly>

Answer 3

1. 将清单文件添加到以下位置。

1. 将第 19 行更改为清单中的以下代码。

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

1. 启动时会提示管理员权限。
