how to fix "CS0121 The call is ambiguous between the following methods or properties: 'Thread.Thread(ThreadStart)' and 'Thread.Thread(ParameterizedThreadStart)'"?

Question

the offending code has
using System;
using System.Windows.Forms;
using System.IO;
using System.Net;
using System.Threading;

and the flagged statement:
new Thread(delegate { getStockInfo(reslt); }).Start();
........

void getStockInfo(string Reslt)
{
.............
}

reslt is of type string and has been assigned value before the thread start.
this is the first attempt to to use thread

Answer 1

Try a short fix:

 new Thread( ( ) => getStockInfo( reslt ) ).Start( );
