C# 将类作为字符串传递并将其从数组中转换

Question

我有几个嵌套类，如“BlueprintsManager.WorkingStandardBlueprint”和具有它们实例的 ArrayList。我想将它们作为参数传递给方法，例如:

private void ShowBlueprints(string class_str, ArrayList class_array)
{
    // class_str would be passed as "BlueprintsManager.WorkingStandardBlueprint"
    // how here I can access class_str as a class and cast class_array to it, to access some variables.
    // for example, I need to access some BlueprintsManager.WorkingStandardBlueprint public variables.
}

我一直在摆弄反射、泛型，但我仍然无法让它工作。

谢谢。

你应该为此使用泛型:

private void ShowBlueprints<T>(List<T> class_array)
{
    for (BlueprintsManager.WorkingStandardBlueprint item in class_array)
    {
        if(typeof T is BlueprintsManager.WorkingStandardBlueprint)
        {
            Console.WriteLine(((BlueprintsManager.WorkingStandardBlueprint)item).whateverpropertyyouhavedefined);
        }
    }
}

现在你可以这样调用方法了:

ShowBluePrints<BlueprintsManager.WorkingStandardBlueprint>(myblueprints);

编辑 在评论中，OP 表示所有属性都是相同的。此解决方案可行:

class BaseClass
{
    string Name {get; set;}
    int id {get; set;}
}

class BlueprintsManager
{
    class WorkingStandardBlueprint : BaseClass
    {

    }
}

private void ShowBlueprints<T>(List<T> class_array) where T : BaseClass
{
    for (T item in class_array)
    {       
        Console.WriteLine(item.Name);
    }
}
