[C #] class and struct differences

From msdn

Structs differ from classes in several important ways:

• Structs are value types (section 11.3.1 ).
• All struct types implicitly inherit from the classSystem. valuetype(Section 11.3.2 ).
• Assignment to a variable of a struct type createsCopyOf the value being assigned (section 11.3.3 ).
• The default value of a struct is the value produced by setting all value type fields to their default value and all reference type fieldsNull(Section 11.3.4 ).
• Boxing and unboxing operations are used to convert between a struct type andObject(Section 11.3.5 ).
• The meaningThisIs different for structs (section 11.3.6 ).
• Instance field declarations for a struct are not permitted to include variable initializers (section 11.3.7 ).
• A struct is not permitted to declare a parameterless instance Constructor (section 11.3.8 ).
• A struct is not permitted to declare a destructor (section 11.3.9 ).
