Check whether the Unicode character is a lowercase letter in C#

To check whether the Unicode character is a lowercase letter, the code is as follows −

Example

using System;
public class Demo {
   public static void Main() {
      bool res;
      char val = 'K';
      Console.WriteLine("Value = "+val);
      res = Char.IsLower(val);
      Console.WriteLine("Is the value a lowercase letter? = "+res);
   }
}

Output

This will produce the following output −

Value = K
Is the value a lowercase letter? = False

Example

Let us see another example −

using System;
public class Demo {
   public static void Main() {
      bool res;
      char val = 'd';
      Console.WriteLine("Value = "+val);
      res = Char.IsLower(val);
      Console.WriteLine("Is the value a lowercase letter? = "+res);
   }
}

Output

This will produce the following output −

Value = d
Is the value a lowercase letter? = True
