Question

I have a string with two different delimiters (| and ~). I want to first split based on one delimiter (|) then loop through the results and split those results by the second delimiter (~). From there I want to take the three values form the second split and assign them to labels on my page.

The problem I am having is with the code below I can only get item[0], for item[1] and item[2] I get an index out of bounds error.

I am not sure where I have gone wrong here and any assistance would be greatly appreciated!

    int rowNumber = 1;
    foreach (string itemArray in ItemList.Text.Split('|'))
    {
        Label tbCM = (Label)FindControl("CM" + rowNumber);
        Label tbCode = (Label)FindControl("Code" + rowNumber);
        Label tbAmt = (Label)FindControl("Amt" + rowNumber);
        HtmlTableRow trItem = (HtmlTableRow)FindControl("trRow" + rowNumber);

        string[] item = itemArray.Split('~');
        tbCM.Text = item[0].TrimStart(',');
        tbCode.Text = item[1];
        tbAmt.Text = item[2];

        trItem.Style.Add("display", "block");

        rowNumber = rowNumber + 1;            
    }

You must check for bad input:

    string[] item = itemArray.Split('~');

    if (item.Length == 3)
    {
        tbCM.Text = item[0].TrimStart(',');
        tbCode.Text = item[1];
        tbAmt.Text = item[2];
    }
    else
    {
        // handle bad input
    }

BTW: You can also do multiple splits in one call:

  string[] Items = itemArray.Split(new char[] {'~', ','});
