Because parameter names could be changed during refactoring, they should not be spelled out literally in strings. Instead, use ``++NameOf()++``, and the string that's output will always be correct.
|
|
|
|
|
|
This rule raises an issue when any string in the ``++Throw++`` statement is an exact match for the name of one of the method parameters.

== Noncompliant Code Example

|
|
|
[source,vbnet]
|
|
----
|
|
Public Sub DoSomething(param As Integer, secondParam As String)
|
|
If (param < 0)
|
|
Throw New Exception("param") ' Noncompliant
|
|
End If
|
|
If secondParam is Nothing
|
|
Throw New Exception("secondParam should be valid") ' Noncompliant
|
|
End If

End Sub

== Compliant Solution

|
[source,vbnet]

----
|
|
Public Sub DoSomething(param As Integer, secondParam As String)
|
|
If (param < 0)
|
|
Throw New Exception(NameOf(param))
|
|
End If
|
|
If secondParam is Nothing
|
|
Throw New Exception($"{NameOf(secondParam)} should be valid")

End If

== Exceptions
|
|
|
|
* The rule doesn't raise any issue when using VB.NET < 14.0.
|
|
* When the parameter name is contained in a sentence inside the ``++Throw++`` statement string, the rule will raise an issue only if the parameter name is at least 5 characters long. This is to avoid false positives.
