#The String class has many methods to help you work with string objects. The following table lists some of the most commonly used methods -

Sr.No	Methods and Instructions
1	public static int Compare(string strA, string strB) Compares two specified string objects and returns an integer indicating Their relative position in the sort order.
2	public static int Compare(string strA, string strB, boolignoreCase) strong> Compares two specified string objects and returns an integer indicating their relative position in the sort order. However, if the boolean parameter is true, case is ignored.
3	public static string Concat(string str0, string str1) Connect two a string object.
4	public static string Concat(string str0, string str1, string str2) Connect three string objects.
5	Public static String Concat(String str0, String str1, String str2, String str3) Connect four string objects.
6	public bool Contains(string value) Returns a value indicating the specified Whether the String object appears in the string.
7	public static string Copy(string str) Create a string with the specified value The same new String object string.
8	public void CopyTo(int sourceIndex, char[] destination, int destinationIndex, int count) Copy the specified number of characters from the specified position of the String object to the specified position in the Unicode character array.
9	public bool EndsWith(string value) Determine whether it is a string object The end matches the specified string.
10	public bool equals(string value) Judge the current String object and the specified Whether String objects have the same value.

Let us look at an example of using the Contains() method in C#. Contains(string value) Returns a value indicating whether the specified String object appears in this string.

Example

using System;
namespace Demo {

   class Program {

      static void Main(string[] args) {
         string str = "This is test";
     
         if (str.Contains("test")) {
            Console.WriteLine("Yes, 'test' was found.");
         }
         Console.ReadKey() ;
