0049 var array type
<![CDATA[
You can create an implicitly-typed array.
We can use var to declare array and let C# figure out the array type.
The type of the array instance is inferred from the elements in the array initializer.
With implicitly-typed arrays, no square brackets are used on the left side of the initialization statement.
using System;
class Program
{
static void Main(string[] args)
{
var anArray = new int[] { 1, 2, 3 };
var rectMatrix = new int[,] // rectMatrix is implicitly of type int[,]
{
{0,1,2},
{3,4,5},
{6,7,8}
};
var jagged = new int[][] // jagged is implicitly of type int[][]
{
new int[] {0,1,2},
new int[] {3,4,5},
new int[] {6,7,8}
};
}
}
For single dimensional array C# can infer the type by converting all array elements to one type.
using System;
class Program
{
static void Main(string[] args)
{
var anArray = new[] { 1, 2, 3 };
}
}
