在c＃中爲URL協議設置路徑＃

Question

因此，我創建了一個URL協議以使用命令參數運行應用程序。

這裏是我的代碼：

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Text; 
using System.Threading.Tasks; 
using System.IO; 
using Microsoft.Win32; 
using System.Diagnostics; 

namespace iw4Protocol 
{ 
    class Program 
    { 
     static void Main(string[] args) 
     { 
      RegistryKey key = Registry.ClassesRoot.OpenSubKey("gameProtocol"); 

      if (key == null) 
      { 
       string iw4FullPath = Directory.GetCurrentDirectory(); 

       gameProtocol protocol = new gameProtocol(); 
       protocol.RegisterProtocol(gameFullPath); 
      } 
      else 
      { 
       RegistryKey gamepathkey = Registry.ClassesRoot.OpenSubKey("gameProtocol"); 
       string gamepath = gamepathkey.GetValue("gamepath").ToString(); 

       Environment.SetEnvironmentVariable("path",gamepath); 



       ProcessStartInfo startInfo = new ProcessStartInfo(); 
       startInfo.FileName = @"test.exe"; 
       startInfo.Arguments = Environment.CommandLine; 
       Process.Start(startInfo); 
      } 
     } 
    } 
} 

的問題是，該方案需要一些文件即可啓動，但由於路徑沒有「設置」無法加載它們。

如何設置此路徑來啓動所有這些所需的文件（如/cd命令）？

如果要設置PATH環境變量，並用它在你的過程中，將其添加到Environment variables但你必須設置UseShellExecute爲false在這種情況下：

ProcessStartInfo startInfo = new ProcessStartInfo(); 
// set environment 
startInfo.UseShellExecute = false; 
startInfo.EnvironmentVariables["PATH"] += ";" + gamepath; 
// you might need more Environment vars, you're on your own here... 
// start the exe 
startInfo.FileName = @"test.exe"; 
startInfo.Arguments = Environment.CommandLine; 

// added for debugging 

startInfo.RedirectStandardOutput = true; 
startInfo.RedirectStandardError = true; 


var p = new Process(); 
p.StartInfo = startInfo; 

using(var sw = new StreamWriter(File.Create("c:\\temp\\debug.txt"))) // make sure C:\temp exist 
{ 
    p.OutputDataReceived += (sender, pargs) => sw.WriteLine(pargs.Data); 
    p.ErrorDataReceived += (sender, pargs) => sw.WriteLine(pargs.Data); 

    p.Start(); 
    p.BeginOutputReadLine(); 
    p.BeginErrorReadLine(); 

    p.WaitForExit(); 
}
