使用自定义业务对象列表作为 ComboBox 数据源

Question

我有 class 这样的：

class MyClass     {
    public string FirstProperty { get; set; }

    public int SecondProperty { get; set; }

public MyClass(int i, string s)
{
    FirstProperty = s;
    SecondProperty = i;
}   

        }

和一个 Winform，代码如下：

List<MyClass> myList = new List<MyClass>();
myList.Add(new MyClass(1, "ABC"));
myList.Add(new MyClass(2, "ZXC"));

comboBox1.DataSource = myList;
comboBox1.ValueMember = "FirstProperty";
comboBox1.DisplayMember = "SecondProperty";

当我执行这段代码时，它出现了 "Cannot bind to new display member" 错误。这在过去对我有用。我做错了什么？

Answer 1

public class MyClass
{
    public string FirstProperty { get; set; }
    public int SecondProperty { get; set; }
}

然后：

var myList = new List<MyClass>
{
    new MyClass {SecondProperty = 1, FirstProperty = "ABC"},
    new MyClass {SecondProperty = 2, FirstProperty = "ZXC"}
};

comboBox1.DataSource = myList;
comboBox1.ValueMember = "FirstProperty";
comboBox1.DisplayMember = "SecondProperty";

希望对您有所帮助。
