Using variable in the name

Question

Is it possible to use a variable to access 2 variables without naming another variable?

For example, to:

LOG.dig.CNLog = 7;
LOG.value.CNLog = 17;

I would like to use something like this

string a = "dig";
string b = "value";
LOG.[a].CNLog = 7;
LOG.[b].CNLog = 17;

It's possible to use this? If yes what is the correct format?

Thanks

@nullforce Given that the OP's problem derives from not knowing the property's name at compile time, then the dynamic dictionary doesn't solve his issue. — dcastro, Aug 16 '14 at 17:00

You can use a Dictionary<string, int>. An example:

var dict = new Dictionary<string, int>();
dict.Add("test", 1);
var testVal = dict["test"];

You can do that by using a Dictionary<TKey, TValue>.

A dictionary is a collection of keys and values. In your case you probably would like to use a Dictionary<string, LogClass> then you can have something like this:

Assuming LogClass is your class...

public class LogClass
{
    public int CNLog { get; set; }
}

string a = "dig";
string b = "value";

dictionary[a].CNLog = 7;
dictionary[b].CNLog = 17;

But of course before doing that you would have to say what is the value that goes into dictionary[var].

dictionary[a] = new LogClass();

That is how you would use it, hopefully you will be able to adapt this solution to your code.

And you can check out a video that explains step-by-step very slowly and clearly how to work with it on Microsoft Virtual Academy: C# Fundamentas at 22:00.
