associative array like in php in vb.net

Question

in PHP we know to make associative array using this code ``` $variable = array('0001'=>'value1', '0010'=>'value2'); ``` and to print all keys and values using this code ``` foreach($variable as $key1 => $val1) foreach($val1 as $key2 => $val2) echo ("$key2 => $val2
") ``` and the question is how to perform this in vb.net? as i know to make associative array in vb.net using this : ``` Dim var As New Collection var.Add("value1", "0001") var.Add("value2", "0010") ``` how about to print value and key in vb.net like foreach in PHP? thanks

Accepted Answer

Although i'm not familiar with PHP (anymore), i assume that associative arrays are the equivalent of a `HashTable` or the more modern, strongly typed `Dictionary`:

```
Dim dict = New Dictionary(Of String, String)
dict.Add("value1", "0001")
dict.Add("value2", "0010")
```

Normally you would lookup keys:

```
Dim val2 = dict("value2") ' <-- 0010
```

But if you want to enumerate it (less efficient):

```
For Each kv As KeyValuePair(Of String, String) In dict
    Console.WriteLine("Key:{0} Value:{1}",kv.Key, kv.Value)
Next
```
