Question

这是我的班级结构

public class Customer
{
     List<Address> add = null;
     public Customer()
     {
         add = new List<Address>();
     }

    public int EmpID { get; set; }
    public string Name { get; set; }

    public List<Address> Address
    {
        get { return add; }
        set { add = value; }
    }
    public double Salary { get; set; }
}

public class Address
{
    public string Address1 { get; set; }
    public string Address2 { get; set; }
    public string PostCode { get; set; }
}


    public void Populate()
    {
        List<Customer> oCust = new List<Customer>()
        {
                new Customer() { EmpID=1, Name="Sonia"},
                new Customer() { EmpID=2, Name="Bill"},
                new Customer() { EmpID=3, Name="Mark"},
        };
    }

从填充方法

我填写客户地址。当我填充客户，然后如何填充地址我不是高级用户，所以请指导我如何使用代码 new Customer() { EmpID=3, Name="Mark" new Address{}}，

请帮助....谢谢

Answer 1

List<Customer> oCust = new List<Customer>()
{
    new Customer() 
    { 
        EmpID = 1, 
        Name = "Sonia", 
        Address = 
        { 
            new Address { Address1 = "foo", Address2 = "bar", PostCode = "pc" },
            new Address { Address1 = "foo 2", Address2 = "bar 2", PostCode = "pc 2" },
        } 
    },
    new Customer() 
    { 
        EmpID = 2, 
        Name = "Bill", 
        Address = 
        { 
            new Address { Address1 = "bill 1", Address2 = "bill 2", PostCode = "bill pc" },
        } 
    }
};

Answer 2

使用collection initializer：

List<Customer> oCust = new List<Customer>()
{
    new Customer() 
    { 
        EmpID=1, 
        Name="Sonia",
        Address = 
        {
            new Address { Address1 = "addr1", Address2 = "addr2", PostCode = "12345" },
            new Address { Address1 = "addr1", Address2 = "addr2", PostCode = "12345" },
            new Address { Address1 = "addr1", Address2 = "addr2", PostCode = "12345" },
        }, 
    },
};

Answer 3

new Customer() { EmpID=1, Name="Sonia", 
                        Address = new List<Address>() { 
                            new Address() { Address1 = "ADDRESS1", PostCode = "000214"} } 
                    },

public class Customer
{
    public int EmpID { get; set; }
    public string Name { get; set; }

    public List<Address> Address { get; set; }

    public double Salary { get; set; }
}

public class Address
{
    public string Address1 { get; set; }

Answer 5

您必须像对待Customer Customer（）一样填充地址。 EmpID = 3，Name =“Mark”，新地址（）{Address1 =“123 Xyz Avenue”，Address2 =“Suite 999”，PostalCode =“11111”}}
