在C中用进程执行dotnet命令#

我有以下C行代码,其中打开进程并运行dotnet命令以打开我的控制台应用程序(使用.net standard/core创建)

var args = new Dictionary<string, string> {
 { "-p", "title"},
 { "-l", "games"},
 ...
};

var arguments = string.Join(" ", args.Select((k) => string.Format("{0} {1}", k.Key, "\"" + k.Value + "\"")));

var dllPath = @"C:\Users\xyz\Documents\Visual Studio 2017\myConsole\bin\Debug\netcoreapp2.1\myConsole.dll";
ProcessStartInfo procStartInfo = new ProcessStartInfo();
procStartInfo.FileName = "C:\....\cmd.exe";
procStartInfo.Arguments = $"dotnet \"{dllPath}\" {arguments}";
procStartInfo.UseShellExecute = false;
procStartInfo.CreateNoWindow = false;
procStartInfo.RedirectStandardOutput = true;
procStartInfo.RedirectStandardError = true;

StringBuilder sb = new StringBuilder();
Process pr = new Process();
pr.StartInfo = procStartInfo;

pr.OutputDataReceived += (s, ev) =>
{
    if (string.IsNullOrWhiteSpace(ev.Data))
    {
        return;
    }

    string[] split = ev.Data.Split(new char[] { '\r', '\n' }, StringSplitOptions.RemoveEmptyEntries);
    int.TryParse(split[split.Length - 1], out output);
};

pr.ErrorDataReceived += (s, err) =>
{
    // do stuff here
};

pr.EnableRaisingEvents = true;
pr.Start();
pr.BeginOutputReadLine();
pr.BeginErrorReadLine();

pr.WaitForExit();

Arguments 结果是:

dotnet "C:\Users\xyz\Documents\Visual Studio 2017\myConsole\bin\Debug\netcoreapp2.1\myConsole.dll" -p "title" -l "games" -s "" -r "none" -k "0" -d "/path/" -f ""

ev.Data OutputDataReceived 事件看起来像:

Microsoft Windows [Version 10.0.16299.665]
(c) 2017 Microsoft Corporation. All rights reserved.

就这样。。。

我希望对dll运行dotnet命令。

如果我手动运行result命令 dotnet .... 上面,工作正常。但不是我的密码。为什么?
