Run an exe from C# code

问题:

I have an exe file reference in my C# project. How do I invoke that exe from my code?

回答1:

using System.Diagnostics;

class Program
{
    static void Main()
    {
        Process.Start("C:\\");
    }
}

If your application needs cmd arguments, use something like this:

using System.Diagnostics;

class Program
{
    static void Main()
    {
        LaunchCommandLineApp();
    }

    /// <summary>
    /// Launch the application with some options set.
    /// </summary>
    static void LaunchCommandLineApp()
    {
        // For the example
        const string ex1 = "C:\\";
        const string ex2 = "C:\\Dir";

        // Use ProcessStartInfo class
        ProcessStartInfo startInfo = new ProcessStartInfo();
        startInfo.CreateNoWindow = false;
        startInfo.UseShellExecute = false;
        startInfo.FileName = "dcm2jpg.exe";
        startInfo.WindowStyle = ProcessWindowStyle.Hidden;
        startInfo.Arguments = "-f j -o \"" + ex1 + "\" -z 1.0 -s y " + ex2;

        try
        {
            // Start the process with the info we specified.
            // Call WaitForExit and then the using statement will close.
            using (Process exeProcess = Process.Start(startInfo))
            {
                exeProcess.WaitForExit();
            }
        }
        catch
        {
             // Log error.
        }
    }
}

Look at Process.Start and Process.StartInfo

回答3:

Example:

System.Diagnostics.Process.Start("mspaint.exe");

Compiling the Code

Copy the code and paste it into the Main method of a console application. Replace "mspaint.exe" with the path to the application you want to run.

Example:

Process process = Process.Start(@"Data\myApp.exe");
int id = process.Id;
Process tempProc = Process.GetProcessById(id);
this.Visible = false;
tempProc.WaitForExit();
this.Visible = true;
