== Why is this an issue?
|
||
|
||
Some constructors of the ``++ArgumentException++``, ``++ArgumentNullException++``, ``++ArgumentOutOfRangeException++`` and ``++DuplicateWaitObjectException++`` classes must be fed with a valid parameter name. This rule raises an issue in two cases:
|
||
|
||
* When this parameter name doesn't match any existing ones.
|
||
* When a call is made to the default (parameterless) constructor
|
||
|
||

||
=== Noncompliant code example
|
||
|
||
[source,csharp]
|
||
----
|
||
public void Foo(Bar a, int[] b)
|
||
{
|
||
throw new ArgumentException(); // Noncompliant
|
||
throw new ArgumentException("My error message", "c"); // Noncompliant
|
||
throw new ArgumentException("My error message", "c", innerException); // Noncompliant
|
||
throw new ArgumentNullException("c"); // Noncompliant
|
||
throw new ArgumentNullException("My error message", "c"); // Noncompliant
|
||
throw new ArgumentOutOfRangeException("c");
|
||
throw new ArgumentOutOfRangeException("c", "My error message"); // Noncompliant
|
||
throw new ArgumentOutOfRangeException("c", b, "My error message"); // Noncompliant
|
||
throw new DuplicateWaitObjectException("c", "My error message"); // Noncompliant
|
||
}
|

=== Compliant solution
|
||
|
||
[source,csharp]
|
||
----
|
||
public void Foo(Bar a, Bar b)
|
||
{
|
||
throw new ArgumentException("My error message", "a");
|
||
throw new ArgumentException("My error message", "b", innerException);
|
||
throw new ArgumentNullException("a");
|
||
throw new ArgumentNullException(nameof(a));
|
||
throw new ArgumentNullException("a", "My error message");
|
||
throw new ArgumentOutOfRangeException("b");
|
||
throw new ArgumentOutOfRangeException("b", "My error message");
|
||
throw new ArgumentOutOfRangeException("b", b, "My error message");
|
||
throw new DuplicateWaitObjectException("b", "My error message");
|
||
}
|
||
----
|
||
|
||
|
||
=== Exceptions
|
||
|
||
The rule won't raise an issue if the parameter name is not a constant value (inline declaration, nameof() or const variable).
