What happens if a static constructor throws an exception in C#?

If a static constructor throws an exception, it is never retried. The type is unusable for the lifetime of the AppDomain. Any further usages of the type will raise a TypeInitializationException wrapped around the original exception.

Can static constructors use optional arguments in C#?

Static constructors can use optional arguments. Overloaded constructors cannot use optional arguments. If we do not provide a constructor, then the compiler provides a zero-argument constructor.

Can static class have constructor in C#?

Yes, a static class can have static constructor, and the use of this constructor is initialization of static member. Suppose you are accessing the first EmployeeName field then constructor get called this time, after that it will not get called, even if you will access same type member.

Why static constructor is Parameterless in C#?

A static constructor must be parameterless because nothing ever calls it, it is invoked when you access a static member or create an instance of the class, but not directly (it is called by the runtime). And also there is no way to call static constructor explicitly.

Why static constructor is used in C#?

A static constructor is used to initialize any static data, or to perform a particular action that needs to be performed only once. It is called automatically before the first instance is created or any static members are referenced.

Can we inherit static class in C#?

Static classes are sealed and therefore cannot be inherited. They cannot inherit from any class except Object. Static classes cannot contain an instance constructor.

Can we overload static constructor in C#?

Static constructors cannot be inherited or overloaded. A static constructor cannot be called directly and is only meant to be called by the common language runtime (CLR). A static constructor is called automatically. It initializes the class before the first instance is created or any static members are referenced.

Can we pass parameters to static constructor?

A static constructor is called automatically to initialize the class before the first instance is created, so we can’t send it any parameters. You cant pass parameters to Static Constructors, because you cannot access any non-static member outside of a static method (constructor too).

Can static constructor have parameters in C#?

A static constructor doesn’t take access modifiers or have parameters. A class or struct can only have one static constructor. Static constructors cannot be inherited or overloaded.

What is the advantage of static class in C#?

The advantage of using a static class is that the compiler can check to make sure that no instance members are accidentally added. The compiler will guarantee that instances of this class cannot be created. Static classes are sealed and therefore cannot be inherited. They cannot inherit from any class except Object.

Can we have a parameterised static constructor in C#?

Do we have static constructor in C#?

In c#, Static Constructor is useful to perform a particular action only once throughout the application. If we declare a constructor as static, it will be invoked only once, irrespective of the number of class instances. It will be called automatically before the first instance is created.
