C-Sharp InStr Example Syntax- InStr - Sample Code

Description: Illustrates the C# Syntax for InStr.

Example Class Main:

using System;
public class clsInStr
{
 
    public void Main()
    {
 
 
 
        //****************************************************************************************
        // Example #1: InStr(startIndex, string1, string2)
        // Returns an integer that represents the position of the first occurrence of 
        // the second string in the first string. The search starts at the specified
        // position in the string.  If the string is not found, the result is 0
        //****************************************************************************************
 
        Console.WriteLine(" InStr(startIndex, string1, string2)");
 
        string strField1 = " This ";
        string strField2 = "is";
 
        Console.WriteLine(strField1.IndexOf(strField2, 0) + 1); //Returns 4 - spaces are counted
 
        //write blank line to make output easier to read
        Console.WriteLine();
 
 
 
        //Prevent console from closing before you press enter
        Console.ReadLine();
 
    }
 
 
}

Example Class Program:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
 
namespace CSharp_Syntax
{
    class Program
    {
        static void Main(string[] args)
        {
 
 
            clsInStr myInStr = new clsInStr();
            myInStr.Main();
 
        }
    }
}
