JsonValueExtensionsAsUInt64 Method
            Gets the specified 
JsonValue as an 
UInt64 value if 
expectedType is 
Undefined
            or matches the 
Type property of the specified 
json parameter and it can be converted to 
UInt64;
            otherwise, returns 
.

- The JsonValue to be converted to UInt64.
- expectedType  JsonValueType  (Optional)
- The expected Type of the specified json parameter,
            or Undefined to allow any type. This parameter is optional.
            
 Default value: Undefined.

.In Visual Basic and C#, you can call this method as an instance method on any object of type 
JsonValue. When you use instance method syntax to call this method, omit the first parameter. For more information, see
