C# C# Objects Inheritance Throwing Exceptions

Why is my code not compiling? Challenge 1 of 1 of Throwing Exceptions

My code won't compile. The question asks me to throw an exception for values < 0 or greater than 20.

Program.cs
int value = int.Parse(Console.ReadLine());

Console.WriteLine(string.Format("You entered {0}",value));

if (value < 0)
{
    throw (System.Exception);
}
else if (value > 20)
{       
    throw (System.Exception);
}

When you throw an exception, it should be typed like:

throw new System.Exception();

The brackets contain the message for the exception (in this case there is no message)

Thanks!
