Execute command line using C#

Question

All I am trying to do is send a command that opens a model with the program.exe Supposed to be super simple!

Ex:

"C:\Program Files (x86)\River Logic\Enterprise Optimizer 7.4 Developer\EO74.exe" "C:\PauloXLS\Constraint Sets_1.cor"

The line above works well if pasted on the command prompt window. However, when trying to pass the same exact string on my code it gets stuck on C:\Program

string EXE = "\"" + @tbx_base_exe.Text.Trim() + "\"";
string Model = "\"" + @mdl_path.Trim()+ "\"";

string ExeModel = EXE + " " + Model;

MessageBox.Show(ExeModel);

ExecuteCommand(ExeModel);

ExeModel is showing te following line on Visual Studio:

"\"C:\\Program Files (x86)\\River Logic\\Enterprise Optimizer 7.4 Developer\\EO74.exe\" \"C:\\PauloXLS\\Constraint Sets_1.cor\""

To me looks like it is the string I need to send in to the following method:

public int ExecuteCommand(string Command)
{
   int ExitCode;
   ProcessStartInfo ProcessInfo;
   Process Process;

   ProcessInfo = new ProcessStartInfo("cmd.exe", "/K " + Command);
   ProcessInfo.CreateNoWindow = true;
   ProcessInfo.UseShellExecute = true;

   Process = Process.Start(ProcessInfo);
   Process.WaitForExit();
   ExitCode = Process.ExitCode;
   Process.Close();

   return ExitCode;
}

Things I've tried:

1. Pass only one command at a time (works as expected), but not an option since the model file will open with another version of the software.
2. Tried to Trim
3. Tried with @ with \"

Can anyone see any obvious mistake? Thanks.

Solution 1

Why are you opening a command prompt (cmd.exe)? Just pass the name of the executable.

Solution 2

It's pretty straightforward. You just create a command line object then write to it, then to execute it you read back from it using SR.ReadToEnd():

private string GETCMD()
{
    string tempGETCMD = null;
    Process CMDprocess = new Process();
    System.Diagnostics.ProcessStartInfo StartInfo = new System.Diagnostics.ProcessStartInfo();
    StartInfo.FileName = "cmd"; //starts cmd window
    StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
    StartInfo.CreateNoWindow = true;
    StartInfo.RedirectStandardInput = true;
    StartInfo.RedirectStandardOutput = true;
    StartInfo.UseShellExecute = false; //required to redirect
    CMDprocess.StartInfo = StartInfo;
    CMDprocess.Start();
    System.IO.StreamReader SR = CMDprocess.StandardOutput;
    System.IO.StreamWriter SW = CMDprocess.StandardInput;
    SW.WriteLine("@echo on");
    SW.WriteLine("cd\\"); //the command you wish to run.....
    SW.WriteLine("cd C:\\Program Files");
    //insert your other commands here
    SW.WriteLine("exit"); //exits command prompt window
    tempGETCMD = SR.ReadToEnd(); //returns results of the command window
    SW.Close();
    SR.Close();
    return tempGETCMD;
}
