A simple question: the difficulty of declaring and using a variable

Question

What's wrong with the following code: I have an error message

Error 1; expected

    <%if (Model.ReferenceFields != null)
          {%>
            <%int count = 1; %>

            <%foreach (var referenceName in Model.ReferenceFields)
            {%>
             <%var value = "value"; %>
             <%count++; %>
             <%value = value + count.ToString(); %>
            <tr>
                <td><input type="hidden" name="Tests.Index" value='<%value%>' /></td>
                <td><input type="text" name="Tests['<%value%>'].Value"/></td>
                <td><input type="button" value= "Add" /></td></tr>
            <%}
               %>
         <%}
        %>

Answer 1

The main problem is lines like this

<input type="hidden" name="Tests.Index" value='<%value%>' />

So you want to write the contents of the value in html, but that is not the way to do it. It should be

<input type="hidden" name="Tests.Index" value='<% Response.Write(value); %>' />

or shortcut for Response.Write is <% = so

<input type="hidden" name="Tests.Index" value='<%= value %>' />

Another problem is that formatting your code, quite frankly with the butt, is ugly, and you are trying to work hard, trying to read it. Try this instead.

<%
if (Model.ReferenceFields != null)
{
    int count = 1; 
    foreach (var referenceName in Model.ReferenceFields)
    {
        var value = "value";
        count++;
        value = value + count.ToString(); 
        %>
        <tr>
        <td><input type="hidden" name="Tests.Index" value='<%= value %>' /></td>
        <td><input type="text" name="Tests['<%= value %>'].Value"/></td>
        <td><input type="button" value= "Add" /></td></tr>
        <%
    }
}
%>
