The System.Exception class should provide what you need.

http://msdn2.microsoft.com/en-us/library/system.exception_members.aspx

The getType() method and message property are good starting places.

Exception is the superclass for numerous exception types:

If you catch Exception, you'll get a polymorphic reference to the actual
subtype.

Reflection will work. If you need to check specifically for
SqlException, it might be easier to do this:

// Assume the exception is in a variable named "exception".
SqlException sqlEx = exception as SqlException;

// If the variable is not null, then use it.
if (sqlEx != null)
{
// Work with sqlEx here.
}

Hope this helps.
