Question

I’m working on some legacy code, so cannot use Generic List here. I have an ArrayList being returned from a data layer method. Each item in the last consists of an ID and a Description field. I want to loop through the ArrayList and search for a match on the Description string – any ideas?

Format

ID    DESCRIPTION
1     SomeValue

I know I can do this:

bool found = false; 
if (arr.IndexOf("SomeValue") >= 0) 
{
    found = true;    
}

But is there a way to do a string compare for a particular Description value?

UPDATE

Amended version of Seattle Badger’s answer:

for (int i = 0; i < arr.Count; i++)
{
    if (arr[i].ToString() == "SomeValue")
    {
        // Do something
        break;
    }
}

I may be missing something in your question, as this seems pretty straight forward to me. But then I’m pretty old-school….

Does this help?

protected void Page_Load(object sender, EventArgs e)
{
    ArrayList arrSample = new ArrayList();

    // populate ArrayList
    arrSample.Items.Add(0, "a");
    arrSample.Items.Add(1, "b");
    arrSample.Items.Add(2, "c");

    // walk through the length of the ArrayList
    for (int i = 0; i < arrSample.Items.Count; i++)
    {
        // you could, of course, use any string variable to search for.
        if (arrSample.Items[i] == "a")
            lbl.Text = arrSample.Items[i].ToString();
    }
}

As I say, not sure if I’m missing something in your question.
