Select items in List that match an interface

Question

I have the following Interfaces defined:

public interface IStep 
{
    string Name { get; set; }
}

public interface IStepBuildDataSet : IStep
{
    DataSet          


        

Answer 1

You could use OfType to make it abit cleaner like this:

IStepBuildDataSet buildDataSet = Steps.OfType().Single();
IStepBuildFile buildFile = Steps.OfType().Single();

Notice, you dont need to cast the results, since OfType does that for you.
