演示代码效果如下所示。
2、 反射操作辅助类ReflectionUtil,如获取或设置字段、属性的值等反射信息。
本辅助类主要是用来方便实现反射操作辅助类,如获取或设置字段、属性的值等反射信息。 在通用的赋值操作(属性或者字段)、执行方法或者需要获取特定对象属性的时候,就需要大量用到反射操作。
1)辅助类提供的方法接口如下所示:
#region 属性字段设置 /// <summary> /// 绑定标识 /// </summary> public static BindingFlags bf = BindingFlags.DeclaredOnly | BindingFlags.Public | BindingFlags.NonPublic | BindingFlags.Instance | BindingFlags.Static; /// <summary> /// 执行方法 /// </summary> /// <param name="obj">对象实例</param> /// <param name="methodName">方法名称</param> /// <param name="args">参数</param> /// <returns></returns> public

resourceHolder, string imageName) /// <summary> /// 获取程序集资源的文本资源 /// </summary> /// <param name="assemblyType">程序集中的某一对象类型</param> /// <param name="resName">资源项名称</param> /// <param

/// 获取程序集嵌入资源的文本形式 /// </summary> /// <param name="assemblyType">程序集中的某一对象类型</param> /// <param name="charset">字符集编码</param> /// <param name="ResName">嵌入资源相对路径</param> /// <returns>如没找到该资源则返回空字符</returns> public static string GetManifestString(Type assemblyType, string charset, string ResName) #endregion #region 创建对应实例 /// <summary> /// 创建对应实例 /// </summary> /// <param

<returns>对应实例</returns> public static object CreateInstance(Type type) #endregion
2)辅助类的使用例子代码如下所示,例子是Socket框架里面用来反序列化对象的操作,通过反射把字符串的值赋值到对象里面。
/// <summary> /// 转换Socket接收到的信息为对象信息 /// </summary> /// <param name="data">Socket接收到的信息</param> public BaseEntity(string data) { string[] dataArray = NetStringUtil.UnPack(data); if (dataArray != null && dataArray.Length > 0) { int i = 0; FieldInfo[] fieldArray = ReflectionUtil.GetFields(this); if (fieldArray == null || dataArray.Length != fieldArray.Length) { throw new ArgumentException("收到的信息和字段信息不一致"); } if (fieldArray != null) { foreach (FieldInfo info in fieldArray) { string strValue = dataArray[i++]; try { if (!string.IsNullOrEmpty(strValue)) { ReflectionUtil.SetField(this, info.Name, strValue); } } catch (Exception ex) { Communication.Model.Log.WriteError(string.Format("转换数据发生错误:{0}【{1}】", ex.Message, data)); break; } } } } }
例如两个对象的属性基本相同,可以进行对象的拷贝赋值。
#region 表结构一样,复制相关的内容 PilotInfo pilotInfo = BLLFactory<Pilot>.Instance.FindByID(txtPilot.PilotID); if (pilotInfo != null) { PropertyInfo[] outPropertyArray = ReflectionUtil.GetProperties(info); PropertyInfo[] pilotPropArray = ReflectionUtil.GetProperties(pilotInfo); if (pilotPropArray != null && outPropertyArray != null) { foreach (PropertyInfo propInfo in pilotPropArray) { try { object value = ReflectionUtil.GetProperty(pilotInfo, propInfo.Name); foreach (PropertyInfo outInfo in outPropertyArray) { if (outInfo.Name == propInfo.Name) { ReflectionUtil.SetProperty(info, propInfo.Name, value); } } } catch (Exception ex) { } } } } #endregion
3、程序集反射创建对象实例辅助类 Reflect
本辅助类主要是用来方便实现程序集反射创建对象实例的操作。 该程序集反射春节对象实例的操作,在我的WInform开发框架中用于对象的创建操作。
1)辅助类提供的方法接口如下所示:
/// <summary> /// 程序集反射创建对象实例辅助类 /// </summary> /// <typeparam name="T">对象类型</typeparam> public class Reflect<T> where T : class { /// <summary> /// 缓存的hash表集合 /// </summary> public static Hashtable ObjCache /// <summary> /// 根据参数创建对象实例 /// </summary> /// <param name="sName">对象全局名称</param> /// <param name="sFilePath">文件路径</param> /// <returns></returns> public static T Create(string sName, string sFilePath) /// <summary> /// 根据参数创建对象实例 /// </summary> /// <param name="sName">对象全局名称</param> /// <param name="sFilePath">文件路径</param> /// <param name="bCache">缓存集合</param> /// <returns></returns> public static T Create(string sName, string sFilePath, bool bCache) /// <summary> /// 创建程序集对象 /// </summary> /// <param name="sFilePath">文件路径</param> /// <returns></returns> public static Assembly CreateAssembly(string sFilePath) }
2)辅助类的使用例子代码如下所示(摘自我的Winform开发框架里面的对象反射操作)。
在下面的例子中,通过传入的类型T,在程序集中构造制定类型的对象,并放入到缓存当中。
public class BLLFactory<T> where T : class { private static Hashtable objCache = new Hashtable(); private static object syncRoot = new Object(); public static T Instance { get { string CacheKey = typeof(T).FullName; T bll = (T)objCache[CacheKey]; //从缓存读取 if (bll == null) { lock (syncRoot) { if (bll == null) { bll = Reflect<T>.Create(typeof(T).FullName, "WHC.WareHouseMis"); //反射创建,并缓存 //bll = Reflect<T>.Create(typeof(T).FullName, System.Reflection.Assembly.GetExecutingAssembly().GetName().Name); //反射创建,并缓存 objCache.Add(typeof(T).FullName, bll); } } } return bll; } } }
4、 正则表达式辅助类 CRegex
本辅助类主要是用来方便实现对正则表达式的封装使用,通过利用该类库,可以简化C#对正则表达式的操作,但不能替代掌握正则表达式的知识。
正则表达式可以通过The Reguator等正则表达式调试工具来验证编写的表达式,基本的操作是匹配,替换,分割等,调试工具界面如下:
1)软件包含下面基础通用的操作正则表达式方法的定义,以及一些封装好的正则表达式操作,如获取HTML标题、Body等内容。
/// <summary> /// 内容是否匹配指定的表达式 /// </summary> /// <param name="sInput">输入内容</param> /// <param name="sRegex">表达式字符串</param> /// <returns></returns> public static bool IsMatch(string sInput, string sRegex) /// <summary> /// 多个匹配内容 /// </summary> /// <param name="sInput">输入内容</param> /// <param name="sRegex">表达式字符串</param> /// <param name="iGroupIndex">第几个分组, 从1开始, 0代表不分组</param> public static List<string> GetList(string sInput, string sRegex, int iGroupIndex) /// <summary> /// 多个匹配内容 /// </summary> /// <param name="sInput">输入内容</param> /// <param name="sRegex">表达式字符串</param> /// <param name="sGroupName">分组名, ""代表不分组</param> public static List<string> GetList(string sInput, string sRegex, string sGroupName) /// <summary> /// 单个匹配内容 /// </summary> /// <param name="sInput">输入内容</param> /// <param name="sRegex">表达式字符串</param> /// <param name="iGroupIndex">分组序号, 从1开始, 0不分组</param> public static string GetText(string sInput, string sRegex, int iGroupIndex) /// <summary> /// 单个匹配内容 /// </summary> /// <param name="sInput">输入内容</param> /// <param name="sRegex">表达式字符串</param> /// <param name="sGroupName">分组名, ""代表不分组</param> public static string GetText(string sInput, string sRegex, string sGroupName) /// <summary> /// 替换指定内容 /// </summary> /// <param name="sInput">输入内容</param> /// <param name="sRegex">表达式字符串</param> /// <param name="sReplace">替换值</param> /// <param name="iGroupIndex">分组序号, 0代表不分组</param> public static string Replace(string sInput, string sRegex, string sReplace, int iGroupIndex) /// <summary> /// 替换指定内容 /// </summary> /// <param name="sInput">输入内容</param> /// <param name="sRegex">表达式字符串</param> /// <param name="sReplace">替换值</param> /// <param name="sGroupName">分组名, "" 代表不分组</param> public static string Replace(string sInput, string sRegex, string sReplace, string sGroupName) /// <summary> /// 分割指定内容 /// </summary> /// <param name="sInput">输入内容</param> /// <param name="sRegex">表达式字符串</param> /// <param name="iStrLen">最小保留字符串长度</param> public static List<string> Split(string sInput, string sRegex, int iStrLen)
5、 压缩文本、字节或者文件的压缩辅助类GZipUtil。
