Chain
Allows chaining together actions to be taken place on the fly. It works with any object. Its a simple concept but I couldn't find any examples that does the same.
Source
public static T Chain<T>(this T source, Action<T> action)
{
action(source);
return source;
}Example
var l = new Collection<SelectListItem>{
new SelectListItem{ Text="t0", Value="y0" },
new SelectListItem{ Text="t1", Value="y1" },
new SelectListItem{ Text="t2", Value="y2" },
new SelectListItem{ Text="t2", Value="y3" },
}.Chain(o => o.ForEachYield(m => m.Selected = (m.Value == "y3")));
