C# 为每个对象动态添加列到 DataTable 属性

Question

当我尝试使用 this accepted answer 将列动态添加到我的 DataTable 时，if 条件永远不会为真。我试过将 struct 更改为 class，并且尝试过在 GetProperties 上使用和不使用 BindingFlags。我错过了什么？

public partial class mainForm : Form
{
    public DataTable DeviceDataTable;
    public mainForm()
    {
        InitializeComponent();
        AttachToTable(new TestObject());
    }
    public void AttachToTable(params object[] data)
    {
        for (int i = 0; i < data.Length; i++)
        {
            if (data[i].GetType().GetProperties(BindingFlags.Public | BindingFlags.Instance).Length > DeviceDataTable.Columns.Count)
                foreach (PropertyInfo info in data[i].GetType().GetProperties(BindingFlags.Public | BindingFlags.Instance))
                {
                    DeviceDataTable.Columns.Add(info.Name, data[i].GetType());
                }
        }
        DeviceDataTable.Rows.Add(data);
    }
    public struct TestObject
    {
        public static readonly string Porperty_One = "First property";
        public static readonly string Porperty_Two = "Second property";
        public static readonly string Porperty_Three = "Third property";
    }
}

您的示例结构很糟糕，因为它没有属性，甚至没有实例，只有静态字段。所以 Type.GetProperties 不会 return 他们。这应该按预期工作：

public class TestObject
{
    public string PorpertyOne   => "First property";
    public string PorpertyTwo   => "Second property";
    public string PorpertyThree => "Third property";
}
