Check whether the specified character has a surrogate code in C#

To check whether the specified character has a surrogate code, the code is as follows −

Example

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 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!
