使用泛型类中的静态方法 [英] Using static method from generic class

问题描述

我遇到上述问题.我的代码:

I have problem as above. My code:

public abstract class BaseFactory<T> where T: class
{
    protected static dbModelContainer context = new dbModelContainer();

    public static int UpdateDataBase_static()
    {
        return context.SaveChanges();
    }
 }

我的问题是我怎么打电话

and my question is how can I call

BaseFactory.UpdateDataBase_static();

代替:

BaseFactory<SomeClass>.UpdateDataBase_static();

有什么想法吗?

推荐答案

您不能，因为没有这样的方法.最接近的是具有泛型类继承自的非泛型基数.然后，您可以在那里使用一种不依赖于参数设置类型的方法.

You can't, because there is no such method. The closest is to have a non-generic base that the generic class inherits from. Then you can have a method there that doesn't depend on the parameterising type.
