在类中使用私有静态变量是否合适？

Question

In a ASP.net web application there are Private static variables which either holds the values from DB tables field or NULL.

private static decimal? X = null;

if (tdataItems.Y != null)
{
    X = tbldataItems.Y;
}

the scope is limited to class and its not shared across pages.

is it good to have such private static variables? i was going through the thread safety issue of static variables so bit confused.

any help or redirection will be highly appreciated!

Thanks!

Answer 1

By default C# class members are private so you can get rid of this access modifier.

Static members are generally thread safe apart from some special cases of Remoting.

But you should be aware while using static members as their scope is not under any object but is completely determined by the CLR and over-usage can compromise efficiency.
