It is expected that some methods should be called with caution, but others, such as ToString, are expected to "just work". Throwing an
exception from such a method is likely to break callers' code unexpectedly.
An issue is raised when an exception is thrown from any of the following:
- Event accessors
-
Object.Equals
-
IEquatable.Equals
-
GetHashCode
-
ToString
-
static constructors
- Module initializers
-
IDisposable.Dispose
- operators
==, !=, <, >, <=, >=
-
implicit cast operators
Noncompliant Code Example
public override string ToString()
{
if (string.IsNullOrEmpty(Name))
{
throw new ArgumentException("..."); // Noncompliant
}
//...
Exceptions
System.NotImplementedException and its derivatives are ignored.
System.InvalidOperationException, System.NotSupportedException, and System.ArgumentException and their
derivatives are ignored in event accessors.
