推荐答案

public IEnumerable<Product> Get()
        {
            return products;
        }

然后你可以做/ api /产品，如果你做了

Then you could do /api/products and if you did

public IEnumerable<Product> Get(int id)
        {
            return products.Where(m=>m.Id == id);
        }

您可以使用/ api / products / 1.



您的另一个选择是使用路由将URL重命名为您想要的。您可以通过属性或RouteConfig.cs文件声明此路由。

You could use /api/products/1.

Your other option is to use routes to rename your URL's to however you want. You can declare this routes via attributes or in your RouteConfig.cs file.
