无法从C＃Process Class运行exe

Question

我正在尝试从C＃.NET Process类执行.exe文件，但我无法这样做。我能够成功地从命令提示符运行.exe。

以下是成功命令提示输出

我使用下面的C＃代码。我没有在下面的代码之外做任何事情。

            string output = string.Empty;
            myProcess.StartInfo.UseShellExecute = false;
            myProcess.StartInfo.WorkingDirectory = @"C:\Windows\System32";
            myProcess.StartInfo.FileName = "pdftotext.exe";
            myProcess.StartInfo.Arguments = " -?";
            myProcess.StartInfo.CreateNoWindow = true;
            myProcess.StartInfo.UseShellExecute = false;
            myProcess.StartInfo.RedirectStandardError = true;
            myProcess.StartInfo.RedirectStandardInput = true;
            myProcess.StartInfo.RedirectStandardOutput = true;
            myProcess.StartInfo.Verb = "runas";
            myProcess.Start();

            using (StreamReader streamReader = myProcess.StandardOutput)
                output = streamReader.ReadToEnd();

            MessageBox.Show("Output = " + output);

以下是上述代码的输出。

Answer 1

myProcess.StartInfo.FileName = "pdftotext.exe"; 

不要放整个文件路径，只需要文件名。

修改

看到我在我的端部尝试了相同的代码，它在我的控制台中正确地给了我输出：

Process myProcess = new Process();


            string output = string.Empty;
            myProcess.StartInfo.UseShellExecute = false;
            // myProcess.StartInfo.WorkingDirectory = @"C:\Windows\System32";
            myProcess.StartInfo.FileName = @"TRACERT.EXE";

            myProcess.StartInfo.CreateNoWindow = true;
            myProcess.StartInfo.UseShellExecute = false;
            myProcess.StartInfo.RedirectStandardError = true;
            myProcess.StartInfo.RedirectStandardInput = true;
            myProcess.StartInfo.RedirectStandardOutput = true;
            //myProcess.StartInfo.Verb = "runas";
            myProcess.Start();

            //Process myProcess =   Process.Start("TRACERT.EXE");

            using (StreamReader streamReader = myProcess.StandardOutput)
            {
                output = streamReader.ReadToEnd();
            }


            Console.WriteLine(output);
            Console.ReadLine();

Answer 2

以下是此代码的成功执行。我不知道为什么我的.exe文件的输出包含在myProcess.StandardError中而不包含在myProcess.StandardOutput

中

我刚给了它不同的参数＆＃34; myProcess.StartInfo.Arguments =＆＃34; -layout D：\ Projects \ OCR \ Invoices \ Sample.pdf＆＃34;它运作良好

System.Diagnostics.Process myProcess = new System.Diagnostics.Process();

        string output = string.Empty;
        string error = string.Empty;

        myProcess.StartInfo.UseShellExecute = false;
        myProcess.StartInfo.FileName = "pdftotext.exe";
        myProcess.StartInfo.Arguments = "-layout D:\\Projects\\OCR\\Invoices\\Sample.pdf D:\\Projects\\OCR\\Invoices\\Sample.txt";
        myProcess.StartInfo.CreateNoWindow = true;
        myProcess.StartInfo.UseShellExecute = false;
        myProcess.StartInfo.RedirectStandardError = true;
        myProcess.StartInfo.RedirectStandardInput = true;
        myProcess.StartInfo.RedirectStandardOutput = true;
        myProcess.StartInfo.Verb = "runas";
        myProcess.Start();

        using (StreamReader streamReader = myProcess.StandardOutput)
            output = streamReader.ReadToEnd();

        using (StreamReader streamReader = myProcess.StandardError)
            error = streamReader.ReadToEnd();

        if (myProcess.ExitCode > 0)
            throw new Exception(ErrorCode(myProcess.ExitCode));
