Char.IsLowSurrogate(String, Int32) Method in C#

CsharpServer Side ProgrammingProgramming

The Char.IsLowSurrogate() method in C# indicates whether the Char object at the specified position in a string is a low surrogate.

Syntax

Following is the syntax −

public static bool IsLowSurrogate (string str, int index);

Above, str is a string, whereas the index is the position of the character to evaluate in str.

Example

Let us now see an example to implement the Char.IsLowSurrogate() method −

using System;
public class Demo {
   public static void Main(){
      string str = new String(new char[] { 'k', 'm', 'g', 't', 'j', 'p', '\uDC00' });
      bool res = Char.IsLowSurrogate(str, 6);
      if (res)
         Console.WriteLine("Contains Low Surrogate value!");
      else
         Console.WriteLine("Does not contain Low Surrogate value!");
   }
}

Output

This will produce the following output −

Contains Low Surrogate value!

Example

Let us now see another example −

using System;
public class Demo {
   public static void Main(){
      string str = new String(new char[] { 'k', 'm', 'g', 't', 'j', 'p', '\uDC00' });
      bool res = Char.IsLowSurrogate(str, 3);
      if (res)
         Console.WriteLine("Contains Low Surrogate value!");
      else
         Console.WriteLine("Does not contain Low Surrogate value!");
   }
}

Output

This will produce the following output −

Does not contain Low Surrogate value!
