Example

[Visual Basic, C#, C++] The following sample demonstrates IsWhiteSpace.

[Visual Basic] 
imports System

Module IsWhiteSpaceSample

    Sub Main()

        Dim str As String
        str = "black matter"

        Console.WriteLine(Char.IsWhiteSpace("A"c))      ' Output: "False"
        Console.WriteLine(Char.IsWhiteSpace(str, 5))    ' Output: "True"

    End Sub

End Module

[C#] 
using System;

public class IsWhiteSpaceSample {
    public static void Main() {
        string str = "black matter"; 

        Console.WriteLine(Char.IsWhiteSpace('A'));        // Output: "False"
        Console.WriteLine(Char.IsWhiteSpace(str, 5));    // Output: "True"
    }
}

[C++]
