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 ... ?

1 solution

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.

Don't you mean .ToList<string> ? Status.Complete is not part of any built-in syntax related to actual files in .NET ... that I could find. I suspect he's using a custom Class.

Probably along those lines - but I have modified my answer incorporating your inspiration for what is possibly the solution.
