Why is this an issue?
A method using the VarArgs
calling convention is not Common Language Specification (CLS) compliant and might not be accessible across
programming languages, while the params
keyword works the same way and is CLS compliant.
This rule raises an issue when a public
or protected
type contains a public
or protected
method
that uses the VarArgs
calling convention.
Noncompliant code example
using System;
namespace MyLibrary
{
public class Foo
{
public void Bar(__arglist) // Noncompliant
{
ArgIterator argumentIterator = new ArgIterator(__arglist);
for(int i = 0; i < argumentIterator.GetRemainingCount(); i++)
{
Console.WriteLine(
__refvalue(argumentIterator.GetNextArg(), string));
}
}
}
}
Compliant solution
using System;
[assembly: CLSCompliant(true)]
namespace MyLibrary
{
public class Foo
{
public void Bar(params string[] wordList)
{
for(int i = 0; i < wordList.Length; i++)
{
Console.WriteLine(wordList[i]);
}
}
}
}
Exceptions
Interop methods using VarArgs
calling convention do not raise an issue.
[DllImport("msvcrt40.dll")]
public static extern int printf(string format, __arglist); // Compliant
