Ninject conditional binding based on property value

Question

I am having trouble defining bindings using ninject.

I am in a standard ASP.NET WebForms application. I have defined an http handler to Inject dependencies in pages

Answer 1

What I'm using (with Ninject 3 now) is a little different but it works for me. I create an array of dependencies and let them decide if they accept to handle the request or not. For example if I had this case

public enum FileFormat
{
    Pdf,
    Word,
    Excel,
    Text,
    Tex,
    Html
}

public interface IFileWriter
{
    bool Supports(FileFormat format)

    ...
}

public class FileProcessor
{
    FileProcessor(IFileWriter[] writers)
    {
        // build a dictionary with writers accepting different formats 
        // and choose them when needed
    }
}

public class MyModule : NinjectModule
{
     public override void Load()
     {
         ...

         Bind().To();
         Bind().To();
         Bind().To();
         Bind().To();
         Bind().To();
     }
}

I hope that helps!
