C # Learning (4)-using the shell to invoke an external EXE app

First create a Windows Forms program, where you add a button, and a textbox

Next we'll first invoke the HelloWorld we wrote before in the command prompt.

C:\Users\gao\Desktop\Hello.exe represents my hello where the app is generated, followed by the two strings that represent the two arguments that hello will use, and then enter both to get a result

Three next, use the button to output the Hello.exe run results to a TextBox

Double-click the button to add code

    private void Button1_Click (object sender, EventArgs e)        {            Process process = new process ();            Process. Startinfo.filename = "cmd.exe";            Process. Startinfo.useshellexecute = false;            Process. Startinfo.redirectstandardinput = true;            Process. Startinfo.redirectstandardoutput = true;            Process. Startinfo.redirectstandarderror = true;            Process. Startinfo.createnowindow = true;            Process. Start ();            String str = @ "C:\Users\gao\Desktop\Hello.exe" + "Fengye C #";                   Process. Standardinput.writeline (str);            Process. Standardinput.writeline ("Exit");            String sh = process. Standardoutput.readtoend ();                        Process. Close ();            This.textBox1.Text = sh;                   }

The results of the operation are as follows:
