Question

My company has a zero warning tolerance policy and I have a warning that I just can’t get to go away. It is showing on the declaration of the string because

Warning 1   The variable 'message' is assigned but its value is never used  

This is the code snippet:

<% 
    string message = "Message to be displayed";
    if (Model.Count == 0)
    {
        %>
        No records to display. <%= message %>
        <%
    }
    else
    {
%>

The rest of the code is correct, so it’s not a syntax error.

Why would this kind of warning appear in the first place when I am clearly referencing it?

Thx in advance!

Answer 1

Change the declare as below, this issue will be fixed.

When you see this kind of warning, just review the declare. It will OK then.

<% 
if (Model.Count == 0)
{
    string message = "Message to be displayed";  // declare message here :)
    %>
    No records to display. <%= message %>
    <%
}
else
{
%>

Best regards.
