for(int i = 1; i <= currentSize; i++) list[i] = valuesHolder[i]; This part is the culprit. You have to copy contents of ‘list’ to newly created array ‘valuesHolder’. Instead you are doing the other way, which results in ‘null’ entries. The change you have to make is this: for(int i = 1; i <= currentSize; … Read more
Do not use this answer, just use Select() method much simpler. class Program { static void Main(string[] args) { string[] s = new string[] { “hi”, “hello”, “what’s up” }; string[] newS = s.ArrayTo<string>(x => x.Remove(0, 1) ); foreach (string str in newS) Console.WriteLine(str); } } static class Ext { public static T[] ArrayTo<T>(this T[] … Read more
You are trying to convert a list of integer to a string string qty = new List<int>(); maybe doing List<int> qty = new List<int>(); solved Cannot implicitly convert type ‘System.Collections.Generic.List‘ to ‘string’
My guess is you’re trying to set the Classproperty of all the students in the list at once. You can do this with the ForEachextension method (include using System.Linq): class Student { public int Id { get; set; } public string Name { get; set; } public int? Class { get; set; } } public … Read more
While looking at your code, why would one want to read class specific properties in a generic method? The only solutions i see is to use Reflection, or create an abstract base class with a before save method and call that method in de Save() method. Add a generic type constraint to the DBObject class … Read more
I solved using Generics in this way in the BaseFactory: public T Create<T>() { return (T)Activator.CreateInstance(typeof(T), this); } then my DerivedFactory is simply this: namespace FunzIA.DL.Factory { public class SocietyFactory : BaseFactory {} } so i can write Society actual = SocietyFactory.InitCreation() .WithCode(idExpected) .Create<Societa>(); solved Create a base fluent ordered constructor
