使用 MVC2 向构造函数添加多个参数

我有以下 LINQ 查询，它从数据库返回两个对象。这些对象将由强类型化为显示模板的 ViewModel 使用：

 public IQueryable<ICustomerSiteRepository> CustomerAndSites
 {
     get
     {
         return from customer in customerTable
                    join site in customerSitesTable
                        on customer.Id equals site.CustomerId
                select new CustomersAndSitesMix(customer, site);
     }
}

我正在尝试创建一个新的 CustomersAndSitesMix 类，其构造函数接受两个参数（客户和网站）。

但是，当我创建类并尝试像这样设置构造函数时：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace CustomerDatabase.Domain.Entities
{
    public class CustomersAndSitesMix (CustomerSite custSite, Customer cust)
    {
    }
}

我收到语法错误，指出不能在 for、using 或fixed 声明中使用多种类型。
我做错了什么？

原文

I have the following LINQ query that returns two objects from my database. These objects will be consumed by a ViewModel that is strongly typed to a display template:

 public IQueryable<ICustomerSiteRepository> CustomerAndSites
 {
     get
     {
         return from customer in customerTable
                    join site in customerSitesTable
                        on customer.Id equals site.CustomerId
                select new CustomersAndSitesMix(customer, site);
     }
}

I am trying to create a new CustomersAndSitesMix class with a constructor that accepts two parameters (the customer and the site).

However, when I create the class and try to set up the constructor like so:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace CustomerDatabase.Domain.Entities
{
    public class CustomersAndSitesMix (CustomerSite custSite, Customer cust)
    {
    }
}

I get syntax errors stating that cannot use more than one type in a for, using or fixed declaration.
What am I doing wrong?

您应该首先声明该类：

// This is the namespace
namespace CustomerDatabase.Domain.Entities
{
    // This is the class declration
    public class CustomersAndSitesMix
    {
        // this is the constructor
        public CustomersAndSitesMix(CustomerSite custSite, Customer cust)
        {
        }
    }
}

You should declare the class first:

// This is the namespace
namespace CustomerDatabase.Domain.Entities
{
    // This is the class declration
    public class CustomersAndSitesMix
    {
        // this is the constructor
        public CustomersAndSitesMix(CustomerSite custSite, Customer cust)
        {
        }
    }
}
