C#中通过反射获取类中非公有成员
public class NGlbGlobeXComm
{
    public static T GetPrivateField<T>(object instance, string fieldname)
            {                
                BindingFlags flag = BindingFlags.Instance | BindingFlags.NonPublic;
                Type type = instance.GetType();
                FieldInfo field = type.GetField(fieldname, flag);
                T to = default(T);
                try
                {
                    to = (T)field.GetValue(instance);
                }catch(Exception e){}
                return to;
            }
}
public class NGlbFieldX : NObjectSafety, INGlbFieldX
 {
            private string mpr_org = null;
            public NGlbFieldX()
            {
                mpr_org = new NGlbField();
            }
}
如果需要获取NGlbFieldX中的mpr_org成员 使用如下语句
string fd = NGlbGlobeXComm.GetPrivateField<string>(field, "mpr_org");
即可得到。
参考:
一般而言,非公共成员是受保护的,不能被外部访问的,这些都是基于安全性考虑。可是有时,我们很想取到非公共成员的某个对象。那我们就得用到两个方法:
GetType().GetField();
GetType().GetProperty();
GetField()用来获取字段,GetProperty()用来获取属性。

    protected void GV_Event_RowCommand(object sender, GridViewCommandEventArgs e)         {             if (e.CommandName == "gvwEventLinkButton")             {                 //_row  前面蓝色小图标,是变量(字段),  他是私有成员                   //Row  前面白色小图标,是属性 ,他是保护乘员(白色图标上有个H的区域)                   //是字段还是属性,根据命名也能看出来                    //根据调试时查看,Row类型是GridViewRow                   GridViewRow row = null;                 System.Reflection.FieldInfo fRow = e.GetType().GetField("_row", BindingFlags.Instance | BindingFlags.NonPublic);                 row = fRow.GetValue(e) as GridViewRow;                 int rowIndex = row.RowIndex;                 GridViewRow row2 = null;                 System.Reflection.PropertyInfo pRow = e.GetType().GetProperty("Row", BindingFlags.Instance | BindingFlags.NonPublic);                 row2 = pRow.GetValue(e, null) as GridViewRow;                 int rowIndex2 = row2.RowIndex;                  //如果RowIndex仍然是非公成员,可以同理对row进行反射操作               }         }

BindingFlags.DeclaredOnly,表示仅搜索在Type 上声明的字段,而不搜索简单继承的字段。
