get,set and value keyword in c#.net

Question

What is value keyword here and how is it assigning the value to _num? I\'m pretty confused, please give the description for the following code.

Answer 1

The value keyword is a contextual keyword, that is, it has a different meaning based on its context.

Inside a set block, it simply means the value that the programmer has set it to. For instance,

className.num = 5;

In this case, value would be equal to 5 inside of the set block. So you could write:

set
{
    int temp = value; //temp = 5
    if (temp == 5) //true
    {
        //do stuff
    }
    _num = value;
}

Outside of a set block, you can use value as a variable identifier, as such:

int value = 5;

Note that you cannot do this inside a set block.

Side note: You should capitalize the property num to Num; this is a common convention that makes it easier for someone who's reading your class to identify public and private properties.
