Question

我有3个班级，经理，TeamLead，雇员。这些都是在我使用实体框架时从数据库生成的。我在这里不能做任何更改。

Class Manager()
{
string AddressLine1;
string AddressLine2;
string AddressLine3;
.
.
//Some other props
}

Class TeamLead()
{
string AddressLine1;
string AddressLine2;
string AddressLine3;
.
.
//Some other props
}

Class Employee()
{
string AddressLine1;
string AddressLine2;
string AddressLine3;
.
.
//Some other props
}

现在我在另一个程序集中的另一个类，

Class AddressDetails
{
string AddressLine1;
string AddressLine2;
string AddressLine3;
}

当前的代码是

Class WorkingPlace
{
Manager _manager;
TeamLead _teamLead;
Employee _employee;
// all the above obejects getting filled in various functions in this class

AddressDetails _addressDetails;

private SomeMethod1()
{
.
.
//doing some works
.
.

FillAddress("Manager");
}

private SomeMethod2()
{
.
.
//doing some works
.
.

FillAddress("TeamLead");
}

private FillAddress(string type)
{
if(type == "Manager")
{
_addressDetails.AddressLine1 = _manager.AddressLine1;
_addressDetails.AddressLine1 = _manager.AddressLine1;
_addressDetails.AddressLine1 = _manager.AddressLine1;

}
else if( type == "TeamLead")
{
_addressDetails.AddressLine1 = _teamLead.AddressLine1;
_addressDetails.AddressLine1 = _teamLead.AddressLine1;
_addressDetails.AddressLine1 = _teamLead.AddressLine1;

}

}
}

我希望这样，

FillAddress<T>(T typeObj)
{
_addressDetails.AddressLine1 = typeObj.AddressLine1;
_addressDetails.AddressLine1 = typeObj.AddressLine1;
_addressDetails.AddressLine1 = typeObj.AddressLine1;

}

//and Call it as,

FillAddress<Manager>(_manager);

有可能，我是Generics的新手，我想有效地编码。高手请帮帮我。除此之外，还有其他任何评论让我知道。

Answer 1

没有回答问题，但我认为需要重构代码，为了避免在此处重复代码，考虑创建Address类，并将其添加为所有其他类的引用

Class AddressDetails
{
   string AddressLine1;
   string AddressLine2;
   string AddressLine3;
}

然后将其他课程设置为

class Manager 
{
   AddressDetails address;
   public Manager(AddressDetails address){
      this.address=address;
   }
}

class Employee
{
   AddressDetails address;
    public Manager(AddressDetails address){
      this.address=address;
   }
}

更好的是，为所有员工使用基类，因为Manager和TeamLead都是员工，并且都有地址。让其他人从中衍生出来。

现在要回答您的问题，请从AddressDetails类派生一个接口，然后让您的其他类实现它。然后创建您的通用方法

FillAddress(IAddressable employee, Addresdetails newAddress)
{
     employee.AddresssLine1=newAddress.AddressLine1;
      ..........
}

Answer 2

Here是有关通用方法的MSDN优秀文章。它应该解释您需要知道的一切。

回答您的问题：

是，这是可能的。

格式化通用方法的猜测的方法是正确的。另外，您可以省略ObjectID部分，如上述文章所述，因为编译器将从参数中推断出类型。

Answer 3

如我所见，您可能需要进行一些反思。假设您已经实例化了void FillAddress<T>(T value){ var typeInfo = typeOf(value); _addressDetails.AddressLine1 = typeInfo.GetProperty("AddressLine1")?.GetValue(value) as string; _addressDetails.AddressLine2 = typeInfo.GetProperty("AddressLine2")?.GetValue(value) as string; _addressDetails.AddressLine3 = typeInfo.GetProperty("AddressLine3")?.GetValue(value) as string; }，则可以执行以下操作：

LoginViewController 
MainTabController
