在类构造函数C＃中传递可变数量的参数(Passing variable number of parameters in class constructor C#)

 我有一个类EvoObject.cs ，其构造函数定义为： 
 
public class EvoObject
{
    private Object _id;
    private List<List<Int32>> _attributes;

    public EvoObject(Object _id, params List<Int32> _args)
    {
        List<Int32> _attrib = new List<int>();

        Debug.Assert(_args.Count >= 2, "Invalid attributes!");

        this._id = _id;
        _attributes = new List<List<Int32>>(_args.Count);

        for (int _i = 0; _i < _args.Count; _i++)
        {
            _attrib.Add(_args[_i]);
        }

        _attributes.Add(_attrib);
    }
}  
 
 其中我使用params接受可变数量的参数。 
 
 现在我在另一个类中有另一个方法，它返回新的EvoObject ： 
 
return new EvoObject(_author, _coAuthors, _papers, _venues);  
 
 我希望与之相关 
 
 
 
 _author with Object _id 
 
 
 _coAuthors ， _papers ， _venues with params List<Int32> _args 
 
 
 在类EvoObject.cs构造函数中，而_coAuthors ， _papers和_venues ：都是List<Int32>类型的List<Int32> 
 
 我遇到错误： 
 
return new EvoObject(_author, _coAuthors, _papers, _venues);  
 
 即EvoObject does not contains a constructor that takes 4 arguments 。 
 
 params如何在这里有用？ 

I have a class EvoObject.cs which has a constructor defined as: 
 
public class EvoObject
{
    private Object _id;
    private List<List<Int32>> _attributes;

    public EvoObject(Object _id, params List<Int32> _args)
    {
        List<Int32> _attrib = new List<int>();

        Debug.Assert(_args.Count >= 2, "Invalid attributes!");

        this._id = _id;
        _attributes = new List<List<Int32>>(_args.Count);

        for (int _i = 0; _i < _args.Count; _i++)
        {
            _attrib.Add(_args[_i]);
        }

        _attributes.Add(_attrib);
    }
}  
 
in which I have used params for accepting variable number of parameters. 
 
Now I have another method in another class which returns new EvoObject as: 
 
return new EvoObject(_author, _coAuthors, _papers, _venues);  
 
in which I want to relate 
 
 
 
_author with Object _id
 
 
_coAuthors, _papers, _venues with params List<Int32> _args 
 
 
in constructor of class EvoObject.cs whereas _coAuthors, _papers and _venues: all are lists of type List<Int32> 
 
I'm getting error at line: 
 
return new EvoObject(_author, _coAuthors, _papers, _venues);  
 
i.e. EvoObject does not contains a constructor that takes 4 arguments. 
 
How params can be useful here?
