[nfbcs] help with trivia game in C#

[Drenth, Joe]

Hi Jessica,

Error CS0120 means that you are calling a function of a class as if it were a static member function (perhaps calling it using the class name on the left of the period), but the function is not static, so you need to have an object instantiation on the left of the period. 

For example, the function "Is Null or Empty" is a static member of the String class, so it is called like this:

 If (String.IsNullOrEmpty (myString))
{ ... }

You can tell it is static by looking at the Syntax description of it on the MSDN page, which shows:

public static bool IsNullOrEmpty (string value)

On the other hand, the String function "Contains" is not a static function, so it is called like this:

If (myString.Contains ("abc"))
{ ... }

The Syntax of this function is as follows, which does not contain the keyword "static":
public bool Contains (string value)

If you send the code which is generating the error, I could help point out the proper way to call the specific function.

I can help you with arrays and making a database for your trivia app if you like. You can contact me off-list at:

Hope this helps.

Hi,
I’m trying to create a trivia game in C#.

I need help making arrays, and a database for the questions.

Does anyone have any suggestions on how I can accomplish this?

Also, I have an error. It’s CS0120. Can anyone tell me what it means, and how to fix it?
The description that MSDN provides, is written in suchv a way that it’s hard for me to understand.

Thanks,
Jessica
