Convert.ChangeType 的运用

JOBEntity job=new JOBEntity();

Type t = job.GetType();

PropertyInfo[] info = t.GetProperties();

 foreach(PropertyInfo i in info)

{

       //value 必须保证有效性，否则要对 PropertyType 进行 typeof 判断 

       if(i.PropertyType.IsGenericType)//是否为泛形类型

            i.SetValue(job, Convert.ChangeType(value, i.PropertyType.GetGenericArguments()[0]), null);

       else

            i.SetValue(job, Convert.ChangeType(value,i.PropertyType), null);

}

实体转换成XML

[Serializable]

public class SmtpConfig

{

　　public string Host{get;set;}

　　public int Port{get;set;}

}

SmtpConfig _config=new SmtpConfig{Host="127.0.0.1", Port=21;}

using (StreamWriter sw = new StreamWriter(xmlpath, false, System.Text.Encoding.Default))

{

XmlSerializer xs = new XmlSerializer(typeof(SmtpConfig));

xs.Serialize(sw, _config);

sw.Close();

}

IDataRecord 转换为实体对象

private static void ReaderToEntity(IDataRecord reader, Object entity)      {          for (int i = 0; i < reader.FieldCount; i++)          {              System.Reflection.PropertyInfo propertyInfo = entity.GetType().GetProperty(reader.GetName(i));              if (propertyInfo != null)              {                  if (reader.GetValue(i) != DBNull.Value)                  {                      propertyInfo.SetValue(entity, reader.GetValue(i), null);                  }              }          }      }
