Array of objects with custom index

Question

I have these two classes:

public class Message
{
    string Message;
    string Code;
}

public class MessageInitializer
{
    DataSet ds;
    DataRow dr;
    message[] ms;
}

I want to create a constructor in MessageInitializer like this:

MessageInitializer()
{
    this.ms = new Message[ds.Tables[0].Rows.Count];
    for (int i = 0; i < ds.Tables[0].Rows.Count; i++)
    {
        dr = ds.Tables[0].Rows[i];
        ms[(string)dr.ItemArray[0]] = (string)dr.ItemArray[1];
    }
}

But array's index must be int type. I have no idea how to work this out:

ms[(string)dr.ItemArray[0]] = (string)dr.ItemArray[1];

Update:

Code format is a string like this: [001-001-001], so I can't convert it to integer.

Answer 1

you don't need Message class any more. Using a dictionary as follows solves the problem :

public class MessageInitializer
{
    DataSet ds;
    DataRow dr;
    Dictionary<string, string> ms;
    public MessageInitializer()
    {
        this.ms = new Dictionary<string,string>(ds.Tables[0].Rows.Count);
        for (int i = 0; i < ds.Tables[0].Rows.Count; i++)
        {
            dr = ds.Tables[0].Rows[i];
            ms[(string)dr.ItemArray[0]] = (string)dr.ItemArray[1];
        }
    }
}

I hope this would be helpful.
