什么C＃构造映射到PHP数组？

Question

I will just list out some arrays and ask how to do them in C#.

$myArray = array();

In PHP I don't have to declare a memory size for the array. What if I don't know big I need my array?

$myArray = array("Name" => "Steve");

How do I do the above in C#?

$myArray = array();
$myArray['Names'][0] = "Steve";
$myArray['Names'][1] = "Jim";

How does the above work in C#"?

Answer 1

$myArray = array("Name" => "Steve");

This is a map. PHP doesn't need you to know that, but C# does. You would implement this as:

var myArray = new Dictionary<String, String>();

For your second case

$myArray['Names'][0] = "Steve";

This is a dictionary where the keys are Strings, but the values are String[]. In C#:

var myArray = new Dictionary<String, List<String>>();
