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

CsharpServer Side ProgrammingProgramming

The Char.IsSurrogate() method in C# indicates whether the specified character has a surrogate code unit.

Syntax

Following is the syntax −

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

Above, the parameter str is the 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.IsSurrogate() method −

using System;
public class Demo {
   public static void Main(){
      string str = new String(new char[] { 'k', 'm', 'g', 't', '\uD800' });
      bool res = Char.IsSurrogate(str, 4);
      if (res)
         Console.WriteLine("Contains Surrogate value!");
      else
         Console.WriteLine("Does not contain Surrogate value!");
   }
}

Output

This will produce the following output −

Contains 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', 'w' });
      bool res = Char.IsSurrogate(str, 4);
      if (res)
         Console.WriteLine("Contains Surrogate value!");
      else
         Console.WriteLine("Does not contain Surrogate value!");
   }
}

Output

This will produce the following output −

Does not contain Surrogate value!
