无法将Process.StartInfo.WorkingDirectory设置为从c#调用exe

Question

我正试图使用System.Diagnostics.Process命名空间在C#程序内调用chrome.exe。

mychrome.exe位于路径C:\Program Files(x86(\Google\chrome\Application内

如果我通过传递以下参数调用RunProc函数-(保持exe的绝对路径并保持WorkingDirectory为空(

("C:\Program Files(x86(\Google\Chrome\Application\Chrome.exe"https://www.google.com"，">(工作正常。

但是，有了参数-

("Chrome.exe，"https://www.google.com"，"C:\Program Files(x86(\Google\Chrome\Application">(在步骤proc.Start((；声明-系统找不到指定的文件。

我还在初始化StartInfo时尝试编写WorkingDirectory=workingDir，但仍在寻找解决方案。

class Program
{
    static void Main(string[] args)
    {
        RunProc(@"chrome.exe", @"https://www.google.com", @"C:Program Files (x86)GoogleChromeApplication");
    }
    static bool RunProc(string exe, string args, string workingDir)
    {
        Process proc = new Process
        {
            StartInfo =
            {
                FileName =  exe,
                CreateNoWindow = true,
                RedirectStandardInput = true,
                WindowStyle = ProcessWindowStyle.Hidden,
                UseShellExecute = false,
                RedirectStandardError = true,
                RedirectStandardOutput = true,
                Arguments = args,
                //WorkingDirectory = workingDir
            }
        };
        if (!string.IsNullOrEmpty(workingDir))
        {
            proc.StartInfo.WorkingDirectory = workingDir;
        }
        proc.Start();
        proc.StandardInput.WriteLine(args);
        proc.StandardInput.Flush();
        proc.StandardInput.Close();
        return true;
    }
}

实现这一点的唯一方法是在尝试启动其他进程之前，将您的工作目录更改为传入的工作目录。WorkingDirectory属性就是这样，并且不会以任何方式参与定位要运行的可执行文件。如果您未能提供完全限定的名称，那么这只依赖于您的工作目录和PATH环境变量。

static bool RunProc(string exe, string args, string workingDir)
{
    var prevWorking = Environment.CurrentDirectory;
    try
    {
        Environment.CurrentDirectory = workingDir;
        Process proc = new Process
        {
            StartInfo =
            {
               FileName =  exe,
               CreateNoWindow = true,
               RedirectStandardInput = true,
               WindowStyle = ProcessWindowStyle.Hidden,
               UseShellExecute = false,
               RedirectStandardError = true,
               RedirectStandardOutput = true,
               Arguments = args,
            }
        };
        proc.Start();
        proc.StandardInput.WriteLine(args);
        proc.StandardInput.Flush();
        proc.StandardInput.Close();
        return true;
    }
    finally
    {
        Environment.CurrentDirectory = prevWorking;
    }
}

Answer 2

为什么不直接从.exe所在的路径调用它呢？

Process.Start(@"C:newfolderabcd.exe");

或者只放

proc.StartInfo.WorkingDirectory = @"c:newfolder";

proc.start((之前；

您认为如何在静态方法中组合.exe的绝对路径，并在调用Process start:之前检查该路径是否存在

using System.Diagnostics;
using System.IO;
namespace RunProc
{
    class Program
    {
        static void Main(string[] args)
        {
            RunProc(@"chrome.exe", @"https://www.google.com", @"C:Program Files (x86)GoogleChromeApplication");
        }
        static bool RunProc(string exe, string args, string workingDir)
        {
            string filePath = workingDir + """ + exe;
            if (!File.Exists(filePath))
                return false;
            Process proc = new Process
            {
                StartInfo =
                {
                    FileName =  filePath,
                    CreateNoWindow = true,
                    RedirectStandardInput = true,
                    WindowStyle = ProcessWindowStyle.Hidden,
                    UseShellExecute = false,
                    RedirectStandardError = true,
                    RedirectStandardOutput = true,
                    Arguments = args,
                }
            };
            proc.Start();
            proc.StandardInput.WriteLine(args);
            proc.StandardInput.Flush();
            proc.StandardInput.Close();
            return true;
        }
    }
}

也许，使用DirectoryInfo和FileInfo 的方法RunProc更清晰一些

using System.Diagnostics;
using System.IO;
namespace RunProc
{
    class Program
    {
        static void Main(string[] args)
        {
            FileInfo myRelativeFileExe = new FileInfo(@"chrome.exe");
            DirectoryInfo myAbsoluteFileDir = new DirectoryInfo(@"C:Program Files (x86)GoogleChromeApplication");
            
            RunProc(myRelativeFileExe, myAbsoluteFileDir, @"https://www.google.com");
        }
        static bool RunProc(FileInfo exe, DirectoryInfo workingDir, string args)
        {
            FileInfo myAbsoluteFilePath = new FileInfo(Path.Combine(workingDir.ToString(), exe.ToString()));
            if (!myAbsoluteFilePath.Exists)
                return false;
            Process proc = new Process
            {
                StartInfo =
                {
                    FileName =  myAbsoluteFilePath.FullName,
                    CreateNoWindow = true,
                    RedirectStandardInput = true,
                    WindowStyle = ProcessWindowStyle.Hidden,
                    UseShellExecute = false,
                    RedirectStandardError = true,
                    RedirectStandardOutput = true,
                    Arguments = args,
                }
            };
            proc.Start();
            proc.StandardInput.WriteLine(args);
            proc.StandardInput.Flush();
            proc.StandardInput.Close();
            return true;
        }
    }
}
