Static class

[LIUCKAS]

Hi, i have wrote this code to create a static class public static class Tools { public static Tools() {} } but the complier give me this error : The modifier 'static' is not valid for this item. (referring to the class declaration) What i miss? thanks

Hello You've missed reading MSDN: "The static modifier can be used with fields, methods, properties, operators, events and constructors, but cannot be used with indexers, destructors, or types." With best regards, Andrew

static classes is a new feature in .NET 2.0 (still in beta). Are you sure you're not programming for .NET 1.1? regards

A static class can't create an object and thereby it can't have a construcor. The PROgrammer Niklas Ulvinge aka IDK

Consider: public abstract sealed class Tools { private Tools(){} } The static modifier in c#2.0 is implemented this way.

Thats wrong. In .Net static constructors are allowed which are called the first time the class is used:

public class Blubb() {
static Blubb() {
//Do something
}
}

Note that no more modifiers are allowed and that this constructor cannot be called explicitely (the framwork handles this).

OK thanks. I didn't know that. I'll maby use it someday. The PROgrammer Niklas Ulvinge aka IDK

thank you very much. Actually i'm using .net 1.1, i didn't know that this feature is implemented only in 2.0. I'll try another way...
