Below are some differences between struct and class in C#
- classes are reference types where as struct are value types.
- Null value cannot be assigned to the Struct because it is a non-nullable value type . Whereas the object of a class can be assigned a null value.
- Classes support inheritance but the struct doesn’t.
- struct cannot have destructor but a class can have.
- struct is stored on stack where as objects instantiated for a class are stored in heap.
- struct cannot have field initializers where as class can have.
- You should use the new keyword to initiate the class but for struct it is an option.
- The access modifiers of a struct cannot be protected or protected internal.
