Declaring Variables

Local Variables when declared must be initialized before they are used, otherwise a compile time error will be raised.

“New-ing” Intrinsic Data Types

All intrinsic data types support what is known as a

default constructor. In a nutshell,

this feature allows you to create a variable using the

new keyword, which automatically sets the variable to its default value:

Although it is more cumbersome to use the

new keyword when creating a basic data type variable,

the following is syntactically well-formed C# code and more advisable.

static void NewingDataTypes()

{

Console.WriteLine("=> Using new to create intrinsic data types:");

bool b = new bool(); // Set to false.

int i = new int(); // Set to 0.

double d = new double(); // Set to 0.

DateTime dt = new DateTime(); // Set to 1/1/0001 12:00:00 AM

Console.WriteLine("{0}, {1}, {2}, {3}", b, i, d, dt);

Console.WriteLine();

}
