Usage Note
In Visual Basic and C#, you can call this method as an instance method on any object of type String. When you use instance method syntax to call this method, omit the first parameter. For more information, see https://msdn.microsoft.com/en-us/library/bb384936(v=vs.111) or https://msdn.microsoft.com/en-us/library/bb383977(v=vs.111).
Remarks
Before you try to convert, you can check whether the string can be converted to a Boolean value by calling the IsBool(String) method, which returns true if the string value can be converted.
