无法使用Response.Write（）打印整数值

Question

I have following code that prints some list. The list is printing but the value of integer variable i is not printing.

<%
int i = 1;
try
{
    foreach (LElement r in LElements)
    {
        Response.Write("<br/><div style=\"font-size:small\">");
        Response.Write("Element "+i+"="+r.name);
        Response.Write("</div>");
        i++;
    }
    Response.Write("<br/>");
}
catch (Exception)
{
    Response.Write("Error");
}
%>

Its just printing

Element = ABC

Element = XYZ

and so on...

Resulting HTML is somewhat like this:

<br/><div style="font-size:small">Element = ABC</div>
<br/><div style="font-size:small">Element = XYZ</div>
<br/><div style="font-size:small">Element = PQR</div><br/>

Please tell me what is wrong with this code?

Answer 1

I've tried reproducing your issue and can't so I am guessing either your sample code is quite different from your real code or something deeper is going on? This is what I've done and works OK so you could take this as a starting point and tell us if it works any more than your code and might highlight any mistakes you have made?

<%    
    string[] data = { "ABC", "DEF", "GHI", "XYZ" };
    int i = 1;

    try
    {
        foreach(string item in data)
        {
            Response.Write("<br/><div style=\"font-size:small\">");
            Response.Write(String.Format("Element {0} = {1}", i, item));
            Response.Write("</div>");
            i++;
        }
        Response.Write("<br/>");
    }
    catch (Exception) 
    { 
        Response.Write("Error");
    }
%>

PS I've wrapped the output into a String.Format which will ensure it gets converted to a string correctly.

Answer 2

Response.Write(String.Format("Element {0} = {1}", i, r.name));

Answer 3

Try this:

Response.Write(String.Format("Element {0} = {1}", i, r.name));
