0612 Obtaining array types
<![CDATA[
You can also obtain an array type by calling MakeArrayType on the element type:
using System;
using System.Reflection;
using System.Collections.Generic;
class MainClass
{
static void Main()
{
Type tSimpleArray = typeof(int).MakeArrayType();
Console.WriteLine(tSimpleArray == typeof(int[])); // True
}
}
MakeArray can be passed an integer argument to make multidimensional rectangular arrays:
using System;
using System.Reflection;
using System.Collections.Generic;
class MainClass
{
static void Main()
{
Type tCube = typeof(int).MakeArrayType(3); // cube shaped
Console.WriteLine(tCube == typeof(int[, ,])); // True
}
}
GetElementType does the reverse; it retrieves an array type's element type:
using System;
using System.Reflection;
using System.Collections.Generic;
class MainClass
{
static void Main()
{
Type e = typeof(int[]).GetElementType();
//GetArrayRank returns the number of dimensions of a rectangular array:
int rank = typeof(int[, ,]).GetArrayRank(); // 3
}
}
