C# InStr Example Syntax| C-Sharp InStr | Source Code
Purpose: – Illustrates the C# Syntax for InStr.
Step 1: Click on C# to Cut-n-paste code into clsInStr.cs
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(); } } |
Step 2: Click on C# to Cut-n-paste code into Program.cs
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(); } } } |

Notes:
- Console Application is used to simplify things, but Windows Forms or Web Forms could also be used
- You can build a library of syntax examples by using same project over and over and just commenting out what you do not want to execute in Program.cs
