Question

我正在我的应用程序中创建一个Process，它使用以下参数执行cmd.exe：

REG EXPORT "HKU\S-1-5-21-2198249526-820760291-2548842010-1000\Keyboard Layout\Preload" D:\Backups\Preload.reg

应用程序本身运行时没有异常但在显示Process.StandardError.ReadToEnd()的输出时出错：“错误：访问被拒绝”。

我已经尝试创建app.manifest文件并将requestedExecutionLevel更改为requireAdministrator - 但我仍然遇到同样的错误。

当我在以管理员身份运行的shell中执行命令时，会在指定路径创建.reg-File。

那么，为了提升流程，还有什么我需要指定的吗？那UAC呢？一旦我以管理员身份运行我的应用程序，它就会被禁用，对吗？

我正在使用Visual Studio 2017 Enterprise，目标框架是NETCore app 1.1。

编辑：这是我的代码：

Process process = new Process();
ProcessStartInfo startInfo = new ProcessStartInfo();         
startInfo.FileName = "cmd.exe";

startInfo.CreateNoWindow = true;
startInfo.Arguments = "REG EXPORT \"HKU\S-1-5-21-2198249526-820760291-2548842010-1000\Keyboard Layout\Preload\" D:\Backups\Preload.reg";
startInfo.WorkingDirectory = "D:\\Backups";

process.StartInfo = startInfo;
process.StartInfo.RedirectStandardError = true;
process.Start();
process.WaitForExit();
string error = process.StandardError.ReadToEnd();
Console.Write(error);

我使用以下app.manifest文件运行此代码：

<?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="asInvoker" uiAccess="false" />
        <requestedExecutionLevel  level="requireAdministrator" uiAccess="false" />
        <requestedExecutionLevel  level="highestAvailable" uiAccess="false" />

            Specifying requestedExecutionLevel element will disable file and registry virtualization. 
            Remove this element if your application requires this virtualization for backwards
            compatibility.

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