Question

我有填充ListBox的函数：

private void fillWorkListBox()
{
    this.list = manager.works();
    this.listBox1.DisplayMember = "Название";
    this.listBox1.ValueMember = "ID";

    for (var i = 0; i < this.list.works.Count; i++)
    {
        string name = "№" + this.list.works[i].id + " - " + this.list.works[i].name;

        WorkModel work = new WorkModel();
        work.name = name;
        work.id = this.list.works[i].id;

        listBox1.Items.Add(work);

    }
}

模型是：

class WorkModel
{
    public string name { get; set; }
    public int id { get; set; }
}

当我运行项目时，我在ListBox中看到对象模型work的类型。取而代之的是name，密钥为id。

如何解决？

Answer 1

而不是直接将工作对象添加到列表框中。

执行以下操作。如果您想要显示ID，您也可以附加ID（您可能需要在追加之前转换为字符串）

listBox1.Items.Add("Name: " + work.name + "Key: " + Convert.ToString(work.id));

Answer 2

private void fillWorkListBox()
        {
            IList<WorkModel> managerWorks = new List<WorkModel>
            {
                new WorkModel {name="fooNameOne",id=1 },
                new WorkModel {name="fooNameTwo",id=2 }
            };

            listBox1.DisplayMember = "Название";
            listBox1.ValueMember = "ID";

            WorkModel workModel = new WorkModel();

            for (var i = 0; i < managerWorks.Count; i++)
            {
                string name = "№" + managerWorks[i].id + " - " + managerWorks[i].name;

                workModel.name = name;
                workModel.id = managerWorks[i].id;
                listBox1.Items.Add("Name:" + workModel.name + "Id:" + workModel.id.ToString());
            }
        }

如何在ListBox C＃中显示数据对象？
