poss to use strings to index?

[Glenn]

Hello again,

New question, is it possible to do anything similar to PHP where
you're able to use a string as an index to another?

Say you're reading a file of different types of fruit, and wish to
increment at the same time, so you have something like :
fruit[infruit]++;
as you get in new fruit, you have a new column/row of data, basically.
I figure that I can just have a routine that will return the index for
each type of item/fruit, whatever.. was just wondering of the PHP
method was possible at all.

Thanks
Glenn

What you are looking for is a dictionary. Example:

Dictionary<string, int> fruit = new Dictionary<string, int>;

string infruit = "apple";
if (fruit.ContainsKey(infruit)) {
fruit[infruit]++;
} else {
fruit.Add(infruit, 1);
}

Console.WriteLine("Apples: " + (fruit.ContainsKey("apple") ?
fruit["apple"] : 0).ToString());

Most excellent.. Thank you

Dictionary<string, int> fruit = new Dictionary<string, int>;

Or in general:

Dictionary<string, AnyType> data = new Dictionary<string, AnyType>();

If you're working in .Net 1.1, use Hashtable.
