Code Inspection: Cannot resolve symbol in text argument
This code inspection validates the argument that you pass to the
paramName parameter in constructors of
System.ArgumentException
and its derivatives (e.g.
System.ArgumentNullException,
System.ArgumentOutOfRangeException, etc.).
The
paramName parameter expects the name of the parameter that caused the exception
as it will appear in stack traces to help you quickly find the source of the problem.
Therefore, ReSharper issues a warning if the argument corresponds to none of the parameters of
the method where the exception is thrown.
Moreover, ReSharper is aware of the position of the
paramName parameter in different signatures as shown in the example below.
public void Foo(object value)
{
if(value == null)
// Warning for the first argument
throw new ArgumentNullException("bad value", "value is null");
if(!(value is string))
// Warning for the second argument
throw new ArgumentException("bad value", "value is not string");
// do something
}
