What should files.ToString(string) do?
(It is obviously a syntax error...)

I think you have copied the line from somewhere without understanding the things that it contains. Any key word that will be used as a parameter/value will throw you the error. Rather follow some coding standards to avoid such errors.

Without the necessary details how can we help you? What is the "files" collection: a custom Class you wrote (what you show does not match anything I'm familiar with in WinForms). Is this ASP.NET ? or ... ?

Well yes - string is the type, str is the variable you show.
Try:

C#

FilesCompleted(files.ToList(str));

But it may not work: you don't show the context of the code fragment, and the code as shown won't compile - so str may not exist in the exact context you are coding.

Or, as Bill suggests:

C#

FilesCompleted(files.ToList<string>());

But that is unlikely to work either unless there is a implicit conversion from your file class to a string.

Try:

C#

FilesCompleted(files.Select(f => f.Path).ToList());

Assuming it's the file path you are interested in passing to the delegate.
