That looks like Chinese to me. I can guess what it says, the constructor is not accessible. It is marked "internal". That is invariably done for a good reason, along the lines of "you'll break something if you create your own". If you really, really want to, you can invoke the constructor by using Reflection. ConstructorInfo.Invoke().

Not a BCL q, moved to Windows Forms.
