.net - ListBox.DisplayMember = [String] 我可以以某种方式解决它而不是 .NET 中的字符串吗？

Question

问题是针对对象数据源提出的。所以考虑一下我有一个类

public class Customer{

    public String name;
    public int age;

    public Customer(String name, int age) {
         this.name = name;
         this.age = age;
    }
}

我已经将一个列表框数据绑定(bind)到这些对象的列表中。所以我说

listBox.DisplayMember = "name";

但我的问题是，当我将 Customer 类的名称重构为

public String fullName;

DisplayMember 仍停留在“名称”。这将失败。所以它降低了我重构域对象的能力。有没有办法解决这个问题？

这是 sexier and more flexible solution

片段...

To make a long story short, instead of writing:

textBoxCustomerName.DataBindings.Add("Text", bindingSource, "CustomerName");

my suggestion is to write something like:

dataSource.CreateBinding(textBoxCustomerName, ctl => ctl.Text, data => data.Name);

This way, your code will still run without any problems when you refactor your entities (let’s say, if you rename the customer’s Name property to CompanyName).

很可爱吧？
