C # Value types and reference type value passing and reference passing

Value types and reference types:

Value type: 1, value type fixed, stored on the stack. 2. Cannot inherit, can only implement Interface 3. Derived from ValueType

int double char float byte bool enum struct decimal

Reference type: 1, stored on the stack an address is actually stored in the heap, the size is not fixed. 2. Arrays, classes, interfaces, delegates

String array class interface delegate

Value passing and reference passing:

Value types are passed by value, value types are passed by reference, reference types are passed by value, and reference types are passed by reference.

Value passing: The default pass is a value pass, which copies a copy of the contents of the stack
Reference pass: Ref assigns an alias to the variable
