Cannot get PropertyInfo SetValue to Work for a Structure

This is because a structure is a value type and both SetValue and GetValue
expect Objects causing the arguments to boxed. As a result, the GetValue and
SetValue are working the boxed object rather than on the actual structure.

　　　　object boxedObj = messageReceiveDTO;
       PropertyInfo[] propertys = messageReceiveDTO.GetType().GetProperties();
       foreach (PropertyInfo p in propertys)
       {
       　　if (p.GetValue(messageReceiveDTO, null) == null || p.GetValue(messageReceiveDTO, null).ToString() == "0")
          {
          　　continue;
          }
          p.SetValue(boxedObj, DecryptData(p.GetValue(messageReceiveDTO, null).ToString()), null);
       }
       messageReceiveDTO = (MessageReceiveDTO)boxedObj;

将值类型进行装箱，转换为对象，然后再拆箱就可以修改value。因为MessageReceiveDTO用到地方比较多，不适合再把它修改为类，所以就只能用这个方法了。

public string DecryptData(string decryptData)//用于解密数据

若是有更好的方法，求交流....
