Set array key as string not int?

by

The closest you get in C# is Dictionary<TKey, TValue>:

var dict = new Dictionary<string, string>();
dict["key_name"] = "value1";

Note that a Dictionary<TKey, TValue> is not the same as PHP’s associative array, because it is only accessible by one type of key (TKey — which is string in the above example), as opposed to a combination of string/integer keys (thanks to Pavel for clarifying this point).

That said, I’ve never heard a .NET developer complain about that.

In response to your comment:

// The number of elements in headersSplit will be the number of ':' characters
// in line + 1.
string[] headersSplit = line.Split(':');

string hname = headersSplit[0];

// If you are getting an IndexOutOfRangeException here, it is because your
// headersSplit array has only one element. This tells me that line does not
// contain a ':' character.
string hvalue = headersSplit[1];
