Introduction
I have use Visual Studio 2012 for debugging purpose. But you can use any version of visul studio as per your availability..
Write a C# program to find the number of times a substring appears in the given string
using System;
public class stringexercise
{
public static void Main()
{
string str;
string findstring;
int start = 0;
int cnt = -1;
int index = -1;
Console.Write("Input the original string : ");
str = Console.ReadLine();
Console.Write("Input the string to be searched for : ");
findstring = Console.ReadLine();
while (start != -1)
{
start = str.IndexOf(findstring, index + 1);
cnt += 1;
index = start;
}
Console.Write("The string '{0}' occurs " + cnt + " times.\n", findstring);
Console.ReadLine();
}
}
Result
