// Array initialization syntax using the new keyword.

string[] stringArray = new string[]

{ "one", "two", "three" };

Console.WriteLine("stringArray has {0} elements", stringArray.Length);



// Array initialization syntax without using the new keyword.

bool[] boolArray = { false, false, true };

Console.WriteLine("boolArray has {0} elements", boolArray.Length);

// Array initialization with new keyword and size.

int[] intArray = new int[4] { 20, 22, 23, 0 };

Console.WriteLine("intArray has {0} elements", intArray.Length);

Console.WriteLine();

}

Notice that when you make use of this “curly bracket” syntax, you do not need to specify the



size of the array (seen when constructing the stringArray type), given that this will be inferred by

the number of items within the scope of the curly brackets. Also notice that use of the new keyword

is optional (shown when constructing the boolArray type).

In the case of the intArray declaration, again recall the numeric value specified represents the

number of elements in the array, not the value of the upper bound. If there is a mismatch between

the declared size and the number of initializers, you are issued a compile-time error:
