Implicitly typed variables (var) C# with Example
The var keyword allows a programmer to implicitly type a variable at compile time. var declarations have the same
type as explicitly declared variables.
var squaredNumber = 10 * 10;
var squaredNumberDouble = 10.0 * 10.0;
var builder = new StringBuilder();
var anonymousObject = new
One = SquaredNumber,
Two = SquaredNumberDouble,
Three = Builder
The types of the above variables are int, double, StringBuilder, and an anonymous type respectively.
It is important to note that a var variable is not dynamically typed. SquaredNumber = Builder is not valid since you
are trying to set an int to an instance of StringBuilder
