I need to be able to get something similar to the following to work:
Type type = ??? // something decided at runtime with .GetType or typeof;
object[] entityList = context.Resources.OfType<type>().ToList();
Is this possible? I am able to use .NET 4 if anything new in that allows this.
Based on @Jon Skeet's answer, here's a LINQ extension method:
public static class QueryableExtensions
{
public static IQueryable<TSource> OfType<TSource>(this IQueryable<TSource> queryable,
Type runtimeType)
{
var method = typeof(Queryable).GetMethod(nameof(Queryable.OfType));
var generic = method.MakeGenericMethod(new[] { runtimeType });
return (IQueryable<TSource>)generic.Invoke(null, new[] { queryable });
}
}
