如何抑制特殊方法的“已指定格式但参数不是 iformattable”消息

Question

ReSharpers StringFormatMethodAttribute is a great way to keep track of the arguments on methods which perform string formatting.

So I implemented a method that way:

[StringFormatMethod("format")]
public string Format(string format, params object[] args)
{
    // do formatting by custom formatters
}

This gives me the ability to do things like that

Format("Hello {0}!", world);      // => Hello world!
Format("({0:D2} / {1:D2}", 2, 3); // => (02/03)

or in Visual Basic

Format("Hello {0}!", visualBasic) ' => Hello Visual Basic!

while ReSharper warns me if I miss an argument or its position like so

Format("Hello {1}!", world);
            // ^--- Non-existing argument in format string

Format("Hello {1}!", world, value);
                    // ^--- Argument is not used in format string

The method is using an ICustomFormatter so if I'd do this directly

string.Format(customFormatter, "The thread id is {0:D}", Thread.CurrentThread);

ReSharper does not complain.

Using my method, which uses the custom formatting internally however, makes ReSharper complain with a warning

Format("The thread id is {0:D}", Thread.CurrentThread);
                         // ^--- Formatting is specified,
                         //      but argument is not IFormattable

I don't want to disable this warnings in general, only the formatting issue part and if possible only for my own written methods. So my question is, is there a way, maybe by another attribute to make ReSharper aware, that this method is using a custom formatter internally?

As you (guessing from the user name) learned from a post on the JetBrains developer forum by citizenmatt ,
