C# String Methods

Csharp Programming Server Side Programming

The String class has many methods that help you in working with the string objects. The following table has some of the most commonly used methods −

Sr.No	Method & Description
1	public static int Compare(string strA, string strB) Compares two specified string objects and returns an integer that indicates their relative position in the sort order.
2	public static int Compare(string strA, string strB, bool ignoreCase ) Compares two specified string objects and returns an integer that indicates their relative position in the sort order. However, it ignores case if the Boolean parameter is true.
3	public static string Concat(string str0, string str1) Concatenates two string objects.
4	public static string Concat(string str0, string str1, string str2) Concatenates three string objects.
5	public static string Concat(string str0, string str1, string str2, string str3) Concatenates four string objects.
6	public bool Contains(string value) Returns a value indicating whether the specified String object occurs within this string.
7	public static string Copy(string str) Creates a new String object with the same value as the specified string.
8	public void CopyTo(int sourceIndex, char[] destination, int destinationIndex, int count) Copies a specified number of characters from a specified position of the String object to a specified position in an array of Unicode characters.
9	public bool EndsWith(string value) Determines whether the end of the string object matches the specified string.
10	public bool Equals(string value) Determines whether the current String object and the specified String object have the same value.
11	public static bool Equals(string a, string b) Determines whether two specified String objects have the same value.

Let us see an example to work with Contains() method in C#. The Contains(string value) returns a value indicating whether the specified String object occurs within 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() ;
      }
   }
}
