GetField 找不到属性

Question

FieldInfo myFieldInfo = typeof(GGGGB).GetField("GGGGB_WW", BindingFlags.Public | BindingFlags.NonPublic | BindingFlags.Instance);
怎么也打不到"GGGGB_WW"，类代码如下
using System;
namespace Quanke.Components
{
/// <summary>
/// 实体类GGGGB 。(属性说明自动提取数据库字段的描述信息)
/// </summary>

Answer 1

GGGGB_WW是属性不是字段，你应该用PropertyInfo myPropertyInfo = typeof(GGGGB).GetProperty("GGGGB_WW", BindingFlags.Public | BindingFlags.NonPublic | BindingFlags.Instance); 

Answer 2

代码好乱，问题就是？你有这个字段吗？？？GetField是查找数据成员，是取不到属性成员的。例如： C# code
public class TestClass
{
  public int k;
  public int P{get;set;}
}其中k是field,P是属性。 
所以如果你用GetField("P",...)是取不到的。必须用GetProperty("P",...)
