Hi everybody, i have created a winform application which run Command Prompt Commands but the problems is  i am getting an error Like "Cannot Convert string to char" in this line " psi = new ProcessStartInfo(TextBox1.Text.Split(" ")(0), TextBox1.Text.Split(" ")(1)); "  Can anybody please help me
I also tried 
psi = new ProcessStartInfo(TextBox1.Text.Split(' ')(0), TextBox1.Text.Split(' ')(1));
then i am getting error like Method Name Expected

Please help with this error and how add whitespace in that split.

What I have tried:

using System;
using System.Collections;
using System.Collections.Generic;
using System.Diagnostics;
public partial class Form1:Form
private ProcessStartInfo psi;
private Process cmd;
private delegate void InvokeWithString(string text);
private void Button1_Click(System.Object sender, System.EventArgs e)
try {
} catch (Exception ex) {
if (TextBox1.Text.Contains(" ")) {
psi = new ProcessStartInfo(TextBox1.Text.Split(" ")(0), TextBox1.Text.Split(" ")(1));
} else {
psi = new ProcessStartInfo(TextBox1.Text);
System.Text.Encoding systemencoding = default(System.Text.Encoding);
var _with1 = psi;
_with1.UseShellExecute = false;
_with1.RedirectStandardError = true;
_with1.RedirectStandardOutput = true;
_with1.RedirectStandardInput = true;
_with1.CreateNoWindow = true;
_with1.StandardOutputEncoding = systemencoding;
_with1.StandardErrorEncoding = systemencoding;
cmd = new Process {
StartInfo = psi,
EnableRaisingEvents = true
cmd.ErrorDataReceived += Async_Data_Received;
cmd.OutputDataReceived += Async_Data_Received;
private void Async_Data_Received(object sender, DataReceivedEventArgs e)
this.Invoke(new InvokeWithString(Sync_Output), e.Data);
private void Sync_Output(string text)
TextBox2.AppendText(text + Environment.NewLine);

string.Split() returns an array so you should do:
var arr = TextBox1.Text.Split(' ');
psi = new ProcessStartInfo(arr[0], arr[1]);

Hi Mehdi Gholam,
Thank you , it was working.
You need to pass a char array or string array to split, and you access arrays by index using square brackets rather than curved ones.

TextBox1.Text.Split(new char[]{' '})[0]

No it wont work , if you try this code you will get error like " Method Name Expected "

You didn't even try it. You're getting that error because you're doing this

TextBox1.Text.Split(new char[]{' '})(0)
