C#将类类型作为参数传递 [英] C# Passing a class type as a parameter

问题描述

这是C#吗? 将类类型作为参数传递

我有一个实现接口的类适配器.我想用MyFooClass实例填充数组结构，其中MyFooClass的名称或引用是我希望从外部接收的.我将在适配器代码中实例化它们.

I have a class adapter that implements an Interface. I want to fill an array structure with MyFooClass instances where MyFooClass's name or reference I want to receive it from outside. I'll instantiate them inside my adapter code.

例如:

    public void FillWsvcStructs(DataSet ds, ClassType Baz)
    {
        IFoo.Request = ds.DataTable[0].Request;
        IFoo.Modulebq = string.Empty;
        IFoo.Clasific = string.Empty;
        IFoo.Asignadoa = ds.DataTable[0].Referer;
        IFoo.Solicita = "Jean Paul Goitier";


        // Go with sub-Elems (Also "Interfaceated")
        foreach (DataSet.DataTableRow ar in ds.DataTable[1])
        {
            if ((int) ar.StatusOT != (int)Props.StatusOT.NotOT)
            {
                ///From HERE!
                IElemRequest req = new (Baz)(); // I don't know how to do it here
                ///To HERE!

                req.Id = string.Empty;
                req.Type = string.Empty;
                req.Num = string.Empty;
                req.Message = string.Empty;
                req.Trkorr = ar[1];
                TRequest.Add(req);
            }
        }
    }

推荐答案

泛型和其约束应该可以满足您的要求，我相信:

Generics and their constraints should do what you want, I believe:

public void FillWsvcStructs<ClassType>(DataSet ds) where ClassType : IElemRequest, new()
{
    IFoo.Request = ds.DataTable[0].Request;
    IFoo.Modulebq = string.Empty;
    IFoo.Clasific = string.Empty;
    IFoo.Asignadoa = ds.DataTable[0].Referer;
    IFoo.Solicita = "Jean Paul Goitier";


    // Go with sub-Elems (Also "Interfaceated")
    foreach (DataSet.DataTableRow ar in ds.DataTable[1])
    {
        if ((int) ar.StatusOT != (int)Props.StatusOT.NotOT)
        {
            IElemRequest req = new ClassType();

            req.Id = string.Empty;
            req.Type = string.Empty;
            req.Num = string.Empty;
            req.Message = string.Empty;
            req.Trkorr = ar[1];
            TRequest.Add(req);
        }
    }
}
