Question

Lets say i have a method:

 UpdateObject(IList<MyObject> objs)

and i want to use that method for sending just one object? (i prefer not using method overloading cause i dont want a lot of methods to handle in my interface)

is there a way i could use the same method without doing the following:

UpdateObject(new List<MyObject>(){singleObj})

Answer 1

Maybe you could pass an IEnumerable<MyObject> to that method instead.

Probably the easiest way to append a single element to an IEnumerable<T> is to use this AsIEnumerable extension (although Eric Lippert advises against creating extension for objects):

public static IEnumerable<T> AsIEnumerable<T>(this T obj)
{
    yield return obj;
} 

Now you can use everything as IEnumerable.

UpdateObject(singleObj.AsIEnumerable())
