Hi chuang4630,

Yes it can. Set a breakpoint then when the program breaks right click on the variable you want to change and select Add Watch. Now go to the Watch window and double click on the value you want to change and set it the new value and hit return.
I hope that this was of some help.

In .NET 2.0 it's the generic Dictionary collection.

Here is an example:

Dictionary<string, int> x = new Dictionary<string, int>();
x["a"] = 1;
x["b"] = 2;
if (x.ContainsKey("a"))
    Console.WriteLine(x["a"]);
foreach (KeyValuePair<string, int> item in x) {
    Console.WriteLine(String.Format("{0} -> {1}", item.Key, item.Value));
}

You may use a compound type instead of int.
