c# - 用类型安全泛型方法替换非类型安全

Question

我正在寻找一种方法来替换以下内容:

public class NonTypeSafe
{
    private List<object> contents = new List<object>();
    public List<object> Contents {get { return contents; }};

    public NonTypeSafe(params object[] arguments)
    {
        foreach(object arg in arguments)
        {
            contents.Add(arg);
        }
    }
}

使用类型安全的东西。目的是拥有一个对象，我可以在其中添加许多不同类型的对象。目前，检索对象时必须进行检查，以确定它们是否属于正确的类型/顺序是否正确。

目前我有以下内容:

public class TypeSafe<T1>
  {
    protected List<object> ArgList = new List<object>();

    private readonly T1 arg1;

    public TypeSafe(T1 arg1)
    {
      ArgList.Add(arg1);
      this.arg1 = arg1;
    }

    public T1 Arg1
    {
      get { return (T1) ArgList[ArgList.IndexOf(arg1)]; }
    }
  }



  public class TypeSafe<T1, T2> : TypeSafe<T1>
  {

    private readonly T2 arg2;

    public TypeSafe(T1 arg1, T2 arg2) : base(arg1)
    {
      ArgList.Add(arg2);
      this.arg2 = arg2;
    }

    public T2 Arg2
    {
      get { return (T2) ArgList[ArgList.IndexOf(arg2)]; }
    }
  }

依此类推，将新类添加到我合理预期的最大数量参数。有没有更好的方法来实现这一点？

你是在重新发明 System.Tuple ？

A tuple is a data structure that has a specific number and sequence of elements. An example of a tuple is a data structure with three elements (known as a 3-tuple or triple) that is used to store an identifier such as a person's name in the first element, a year in the second element, and the person's income for that year in the third element.
