组合框显示成员不显示使用列表对象c#

Question

这里是 obj def:

 class TestScanOrder
{
    public long OrderCodeField { get; set; }

    public long PatientCodeField { get; set; }

    public string PatientNameField { get; set; }

    public string PatientVal { get; set; }

    public DateTime DateTimeField { get; set; }


    public TestScanOrder(DateTime dt,long order,long pateintCode,string patientName,string patientVal)
    {
        DateTimeField = dt;
        OrderCodeField = order;
        PatientCodeField = pateintCode;
        PatientNameField = patientName;
        PatientVal = patientVal;
    }

列表是

TestScanOrder[] list = new TestScanOrder[]{ new TestScanOrder( Convert.ToDateTime("06/24/2015"), 1910, 65547, "Raja", 65547 + "~" + 1910 + "~" + 1 ), new TestScanOrder(Convert.ToDateTime("06/25/2015"), 1911, 65548, "Roja", 65548 + "~" + 1911 + "~" + 1 ), new TestScanOrder( Convert.ToDateTime("06/26/2015"), 1912, 65549, "Peter", 65549 + "~" + 1912 + "~" + 2 ), new TestScanOrder( Convert.ToDateTime("06/27/2015"), 1913, 65550, "jaya", 65550 + "~" + 1913 + "~" + 2 ), new TestScanOrder(Convert.ToDateTime("06/28/2015"), 1914, 65551, "Vijaya", 65551 + "~" + 1914 + "~" + 1 ) };

cbPatients.DisplayMember = "PatientName";
cbPatients.DataSource = list;
cbPatients.ValueMember = null;

但是，当我在上面开火时，我得到的就是：

如何在组合框中获取 PatientName 请帮我解决这些问题

Answer 1

在“TestScanOrder”类中，患者姓名的属性是“PatientNameField”，所以使用以下来指定组合框的显示成员-

cbPatients.DisplayMember = "PatientNameField";

当为显示成员指定无效的属性名称时，代码不会中断，而是使用数据源中类的完全限定名称填充组合。
