// Implicitly typed local variables.

var myInt = 0;

var myBool = true;

var myString = "Time, marches on...";

// Print out the underlying type.

Console.WriteLine("myInt is a: {0}", myInt.GetType().Name);

Console.WriteLine("myBool is a: {0}", myBool.GetType().Name);

Console.WriteLine("myString is a: {0}", myString.GetType().Name);

}

Be aware that you can use this implicit typing for any type including arrays, generic types, and

your own custom types:

static void DeclareImplicitVars()

{

...

// More implicitly typed local variables.

var evenNumbers = new int[] { 2, 4, 6, 8 };

var myMinivans = new List();

var myCar = new SportsCar();

Console.WriteLine("evenNumbers is a: {0}", evenNumbers.GetType().Name);

Console.WriteLine("myMinivans is a: {0}", myMinivans.GetType().Name);

Console.WriteLine("myCar is a: {0}", myCar.GetType().Name);

}

If you were to call the DeclareImplicitVars() method from within Main(), you’d find the out-

put shown in Figure 13-1.
