I'm trying to print a 2-dimensional array but can't figure it out.开发者_如何学JAVA
My controller uses this code:
        public ActionResult Test(string str)
    {
         DateTimeOffset offset = new DateTimeOffset(DateTime.Now);
        offset = offset.AddHours(-5);
        string[,] weekDays = new string[7,2];
        for (int i = 0; i < 7; i++)
        {
            weekDays[i,0] = String.Format("{0:yyyy-MM-dd:dddd}", offset); //Date
            weekDays[i,1] = String.Format("{0:dddd}", offset); //Text
            offset = offset.AddHours(24);
        }
        weekDays[0,1] = "Today";
        ViewData["weekDays"] = weekDays;
        return View();
    }
Now I wan't to print this array of weekdays as a dropdown-list and i thought this would work:
                <% foreach (var item in (string[,])ViewData["weekDays"]) 
               { %>
                <option value=" <%= item[0] %> "> <%= item[1] %>  </option>
            <% } %>
But that's not the case, this code output just the first char of the string.
So anyone got a suggestion?
Thanks!

Issue here is that foreach on array will return string as an item (and not an array) so item[0] works as indexer over string to return first character. Use for (or while) loop and that should do the trick:
<script runat="server">
    private string[,] viewData;
    protected string[,] Data
    {
        get
        {
            return viewData ?? (viewData = (string[,])ViewData["weekDays"]);
        }
    }
</script>
<% for (var i=0; i< Data.GetUpperBound(0); i++) 
               { %>
                <option value=" <%= Data[i][0] %> "> ...
            <% } %>
