What is the difference between value type and reference type

What is Reference Type 4. The value types can be divided into two categories. They are predefined types and user-defined types. The predefined types are provided by the programming language. They can be numerical, character type or decimal type.

The numerical types can be integral types, floating point types and decimal types. Integral types can be further classified into signed and unsigned. The signed integers can store positive or negative number. The sbyte, short, int and long are signed data types. The sybte is one byte, short is two bytes, int is four bytes, and long is eight bytes. The unsigned type store positive values.

The byte, ushort, uint and ulong are the examples for unsigned types. The floating-point types can store a numerical value with a decimal point. The float is to store bit single precision floating point value, and the double is used to store bit single precision floating point.

The decimal type is for high precision values. The char data type is used to store a single character in the memory. Sometimes it is required to store true or false value. The Boolean is used for that. Those are some examples of value types provided by the programming language. The user can also create value types. Two such user-defined value types are structure and enumerations. A structure contains data of different types.

It is similar to a class. An example of the structure is as follows. Enumerations are used to increase the readability of the code. It is used to give names to the numbers. An example of enum is as follows. The enum keyword automatically enumerates a list of words by assigning values starting from 0. I like it! A debt of gratitude is in order for sharing!

Form is a class in System. Forms namespace, and is hence a reference type:. To set the form's size and font, we can assign the objects s and f to the form via its properties:. Don't get confused by the double usage of the identifiers Size and Font : now they are referring to members of myForm and not the Size and Font classes.

This double usage is acceptable in C and is applied extensively throughout the. NET framework. As you can see, with s , we've copied over its contents , while in the case of f , we've copied over its reference resulting in two pointers in memory to the same Font object. This means that changes made via s will not affect the form, while changes made via f , will [2]. In-Line Allocation. Previously we said that for value-typed local variables, memory is allocated on the stack.

So does that mean the newly copied Size struct is also allocated on the stack? Therefore, it must, too, be allocated on the heap.

This mode of storage is called "in-line". We've made a slightly simplifying assumption in the diagrams in that Size and Font are depicted as fields in the Form class. We can imagine their definitions look something like this:.

Size size; Font font;. But there is a snag. It would seem reasonable to do this :. Cannot modify the return value of 'System. ClientSize' because it is not a variable. We get the same problem whether we use Size or ClientSize. Imagine ClientSize as a public field rather than a property. The expression myForm. Height would then simply reach through the membership hierarchy in a single step and access the Height member as expected.

But since ClientSize is a property, myForm. You have to assign it a whole new object:. Width, myForm. You might wonder if they could they have saved all this bother by defining Size as a class rather than a struct.
