Question

我正在尝试从对象中获取字段列表。我已经确认该对象正在传入此调用：

var account = SymitarInquiryDeserializer.Deserialize<SymitarAccount>(jString);

当我尝试获取字段时，它返回一个零长度数组，我无法看到我在这里做错了什么。

我的对象定义：

public class SymitarAccount
{
    public int PositionalIndex { get; set; }
    /// <summary>IQ: ~JID: Account/Share Id (format: 0000)</summary>
    [SymitarInquiryDataFormat("ID")]
    public int Id { get; set; }
    /// <summary>IQ: ~JCLOSEDATE: Account/Share Closed Date where 00000000 is still open (format: YYYYMMDD)</summary>
    [SymitarInquiryDataFormat("CLOSEDATE")]
    public DateTime? CloseDate { get; set; }
    public bool IsClosed { get; set; }
    /// <summary>IQ: ~JDIVTYPE: Account/Share Div Type (format: 0)</summary>
    [SymitarInquiryDataFormat("DIVTYPE")]
    public int DivType { get; set; }
    /// <summary>IQ: ~JBALANCE: Account/Share Balance (format: 0.00)</summary>
    [SymitarInquiryDataFormat("BALANCE")]
    public decimal Balance { get; set; }
    /// <summary>IQ: ~JAVAILABLEBALANCE: Account/Share Avaialable Balance (format: 0.00)</summary>
    [SymitarInquiryDataFormat("AVAILABLEBALANCE")]
    public decimal AvailableBalance { get; set; }
}

获取字段的方法：

public static T Deserialize<T>(string str) where T : new()
{
    var result = new T();
    ....
    // Get fields of type T
    var fields = typeof(T).GetFields();    //BindingFlags.Public | BindingFlags.Instance);
    foreach (var field in fields)
    {
        ....
    }
    ....
}

有什么想法吗？

Answer 1

这些不是字段而是属性。请改用GetProperties：

var properties = typeof(T).GetProperties();

Answer 2

GetFields返回公共变量。你所追求的是你可以通过拨打GetProperties

获得的属性名称

Answer 3

public void FindFieldNames<T>(List<T> data)
{
      foreach (var prop in data.GetType().GetProperties())
      {           
           Console.WriteLine($@"{prop.Name}");                
      }    
}

typeof（T）.GetFields（）返回零长度数组
