C# StartsWith() Method

Csharp Server Side Programming Programming

The StartsWith() method in C# is used to determine whether the beginning of this string instance matches the specified string.

Syntax

public bool StartsWith (string val);

Above, val is the string to compare.

Example

Live Demo

using System;
public class Demo {
   public static void Main() {
      string str = "JohnAndJacob";
      Console.WriteLine("String = "+str);
      Console.WriteLine("Does String begins with J? = "+str.StartsWith("J"));
      char[] destArr = new char[20];
      str.CopyTo(1, destArr, 0, 4);
      Console.Write(destArr);
   }
}

Output

This will produce the following output -

String = JohnAndJacob
Does String begins with J? = True

Example

Let us now see another example -

Live Demo

using System;
public class Demo {
   public static void Main(String[] args) {
      string str1 = "Akon";
      string str2 = "Eminem";
      Console.WriteLine("String 1 = "+str1);
      Console.WriteLine("HashCode of String 1 = "+str1.GetHashCode());
      Console.WriteLine("Does String1 begins with E? = "+str1.StartsWith("E"));
      Console.WriteLine("\nString 2 = "+str2);
      Console.WriteLine("HashCode of String 2 = "+str2.GetHashCode());
      Console.WriteLine("Does String2 begins with E? = "+str2.StartsWith("E"));
      Console.WriteLine("\nString 1 is equal to String 2? = {0}", str1.Equals(str2));
   }
}

Output

This will produce the following output -

String 1 = Akon
HashCode of String 1 = 416613838
Does String1 begins with E? = False
String 2 = Eminem
HashCode of String 2 = 40371907
Does String2 begins with E? = True
String 1 is equal to String 2? = False
