Passing by reference: public void Double(ref int numberToDouble) { } Introduction Value types Value types are the simpler of the two. Value types are often used to represent data itself. An integer, a Boolean or a point in 3D space are all examples of good value types. Value types (s...

When we don't know the value a variable takes, we say its value is missing, indicated by NA. Missing values are represented by the symbol NA (not available). Impossible values (e.g., as a result of sqrt(-1)) are represented by the symbol NaN (not a number).

KVC :- Key-Value Coding Normally instance variables are accessed through properties or accessors but KVC gives another way to access variables in form of strings. In this way your class acts like a dictionary and your property name for example “age” becomes key and value that property holds becom...

There is no inherent answer in C# to this - so called - need. Nonetheless there are workarounds to satisfy this need. The reason I qualify the need as "so called" is that we only need methods with 2 or more than 2 values to return when we violate good programming principals. Especially ...

it should be mentioned that if the key value does not exist then this will raise KeyError, in those situations it maybe better to use merge or get which allows you to specify a default value if the key doesn't exist
