Question

What\'s the difference between struct and class in .NET?

Answer 1

From Microsoft's Choosing Between Class and Struct ...

As a rule of thumb, the majority of types in a framework should be classes. There are, however, some situations in which the characteristics of a value type make it more appropriate to use structs.

✓ CONSIDER a struct instead of a class:

• If instances of the type are small and commonly short-lived or are commonly embedded in other objects.

X AVOID a struct unless the type has all of the following characteristics:

• It logically represents a single value, similar to primitive types (int, double, etc.).
• It has an instance size under 16 bytes.
• It is immutable. (cannot be changed)
• It will not have to be boxed frequently.
