static-classes

I'm looking to create a static class called VectorCalculator. Perhaps this function should just be placed in my Vector class (similar to NSString's - -stringByAppendingString method in Obj-C)... and if you think that... let me know. Anyway I want to add a couple of static functions to a static class called VectorCalculator. It will calculate the 'dot product' and return a Vector. Another function will likely be to 'calculate and return the angle between two given vectors'. A) Would anyone go this route of creating a static class for this or B) should I just add these functions as instance

I've dug around SO for an answer to this, and the best one I can find so far is here , however that is geared toward instances with static constructors; I'm only using the class statically. My code: public static class MailHelper { private static string mailHost; static MailHelper() { var mailSettings = ConfigurationManager.GetSection("MailSettings") as NameValueCollection; if (null == mailSettings) { throw new ConfigurationErrorsException("Missing Mail Settings in the configuration file"); } mailHost = ConfigurationManager.AppSettings["mailHost"]; if (null == mailHost) { throw new

We need to use an unmanaged library in our code that has static methods. I'd like to introduce the library operation as a dependency in my code. And apart from having static methods, the library has an initialization method and a settings method, both are global. So I can't just wrap this in an instance class, because if one instance changes a setting, all other instances will be affected, and if one instance gets initialized, all other instances will be reinitialized. I thought about introducing it as a singleton class. This way it will be in an instance class, but there will only be one

Given a static class with an initializer method: public static class Foo { // Class members... internal static init() { // Do some initialization... } } How can I ensure the initializer is run before Main() ? The best I can think of is to add this to Foo : private class Initializer { private static bool isDone = false; public Initializer() { if (!isDone) { init(); isDone = true; } } } private static readonly Initializer initializer = new Initializer(); Will this work or are there some unforeseen caveats? And is there any better way of doing this? Simply do the initialization inside a static

In C# what is the difference between: public static class ClassName {} And: public class ClassName {} lmsasu A static class cannot be instantiated, and can contain only static members. Hence, the calls for a static class are as: MyStaticClass.MyMethod(...) or MyStaticClass.MyConstant . A non static class can be instantiated and may contain non-static members (instance constructors, destructor, indexers). A non-static member of a non-static class is callable only through an object: MyNonStaticClass x = new MyNonStaticClass(...); x.MyNonStaticMethod(...); Firstly, a comment on an answer asked
