Have Geek Brain

Visual Studio 2008 SP1:

"X", here, is a 3rd party component that implements ICollection, and "Y" is Count. It compiles by temporarily removing the squigglies and either shortly after (1-2 seconds) or after making any changes in the text editor it shows red squigglies under Count.?! Any help would be greatly appreciated, thanks.

edit: for example

ThirdPartyComponent instanceOfComponent = new instanceOfComponent();
instanceOfComponent.GetResults();

for(int i = 0; i < instanceOfComponent.Results.Count; ++i) {
    // Some stuff happens
}

Here "Count" is squigglied, although it compiles fine - and even shows up in Intellisense.

From your comment above, it looks like VS is complaining about the ambiguity between Results.Count

and Results.Count()

. It will compile just fine, but it warns you about this possible error. Casting to ICollection

will explicitly tell the compiler which one to use:



for(int i = 0; i < ((ICollection)instanceOfComponent.Results).Count; ++i)

I'm not sure which language you are using, but there are two possible problems here:



  • Count can be a function, not a property.

  • Most likely, the results are a property that returns a class based on List <> and so you are calling the Count property of this Results object, not instanceOfComponent. A simple casting should solve it.

You need to add:
