Website Code Analysis

When I run Code analysis on my website I always get 4 errors, one from
each of my Global.asax functions Application_Error,Application_Start,
Session_End, Session_Start. the error is "'Function Name' appears to
have no upstream public or protected callers." Is this expected?

I guess it is as IIS would call these not any of my code explicitly?

can I tell the code analysis tool to ignore these functions?

TIA

Hello Mike,

As for the "Application_Error,Application_Start, Session_End,
Session_Start" methods, they're really of the special case which will
violate the normal best practice rules defined by the built-in code
analysis categories. Actually, it is the ASP.NET runtime which call the
these methods at the proper time.

For these methods, since they're of the particular case and should be
isolated from other normal functions, you can consider the following
options:

1. Since the warning you get is rule "CA1811: Avoid uncalled private
code", you can modify all the functions in the global.asax file as
"protected" , e.g.

protected void Application_Start(...)

this can help suppress the CA1811 warning in thsi particular case.


2. It is a quite reasonable and normal scenario that we may have some
particular methods or code module which violate the common best practice
though they're under our control. The .net 2.0 code analysis provide
warning suppress setting in different granularity. We can enable/disable
certain rules in IDE/project setting or suppress rules for a particular
unit(method, module ....).

For this case, you can use the "SuppressMessageAttribute" to decorate the
functions in the global.asax against the CA1811 rule.

e.g.

=====================
[System.Diagnostics.CodeAnalysis.SuppressMessage("Microsoft.Performance",
"CA1811")]
void Application_Start(object sender, EventArgs e)
{
................
}

Hope this helps you.
