title: Problems with MessageBox.Show()
body: <p>I'm new to code and most things work, but I can't get this code to run. Can someone help?</p>
  
  <p>I tried <code>using System.Forms</code> but it showed as missing a namespace. When I used <code>using System.Windows.Forms</code> that message went away. It does not let me use both.</p>
  
  <pre><code>using System;
  using System.Collections.Generic;
  using System.Linq;
  using System.Text;
  using System.IO;
  using System.Windows.Forms;
  
  
  namespace ConsoleApplication1
  {
      class Program
      {
          static void Main(string[] args)
          {
              StreamReader sr = new StreamReader(@"file.csv");
              // for set encoding
              // StreamReader sr = new StreamReader(@"file.csv", Encoding.GetEncoding(1250));
  
              string strline = "";
              String[] _values = null;
              int x = 0;
              while(!sr.EndOfStream)
              {
                  strline = sr.ReadLine();
                  _values = strline.Split(',');
                  if (_values.Length &gt;= 6 &amp;&amp; _values[0].Trim().Length &gt; 0)
                  {
                      MessageBox.show(_values[1]);
                  }
              }
              sr.Close();
  
          }
      }
  }
