get string array out of Dictionary<int, string[]>

Question

this is my code

pritvate static Dictionary<int, string[]> _list = new Dictionary<int, string[]>();

how can i get the string[] out of this? I have tried this and a lot more:

string[] s = _list.Values;

but it is all not working.

please help

This cannot work, because _list.Values is of a type similar to string[][]. Maybe you really want to have a Dictionary<int, string>? — SirDarius

You should read documentation about dictionnary I think you did not understand the concept. — Nerevar

Trial and error isnt always the best approach, as @Nerevar already pointed out you should read the documentation. — Rand Random

If you want all string arrays for all keys merged into a single array, you can use LINQ's .SelectMany(...):

var strings = _list.Values.SelectMany(v => v).ToArray()

Reading your question again, I wonder if you're asking how to access a value for a single key. So, if you want the string array for a single key you can simply use the indexer:

var value = _list["keyname"];

But that will cause an exception if the key doesn't exist. If you're not sure that the key exists, you can use .TryGetValue(...):

string[] value;
if (_list.TryGetValue("keyname", out value))
{
    // value was found
}
else
{
    // value wasn't found
}
