项目中常用类

项目中常用类1.分页数据模型：PagedDataModel.cs

用处：将分页的数据，封装到类中

public class PagedDataModel<T>{ /// <summary> /// 总页数 /// </summary> public int PageCount; /// <summary> /// 总行数 /// </summary> public int RowCount; /// <summary> /// 当前页码 /// </summary> public int PageIndex; /// <summary> /// 当前页码数据 /// </summary> public IList<T> PagedList;}

2.数据帮助类：DataHelper.cs

用处：对数据进行处理，以一定格式返回

public static class DataHelper{ /// <summary> /// js序列化器 /// </summary> static javaScriptSerializer jss=new JavascriptSerializer(); /// <summary> /// 将对象转换为json数组格式字符串 /// </summary> /// <param name="obj"></param> /// <returns></returns> public static string ObjToJson(object obj) { return jss.Serialize(obj); } /// <summary> /// 返回md5加密字符串 /// </summary> /// <param name="str"></param> /// <returns></returns> public static string MD5(string str) { return System.Web.Security.FormsAuthentication.HashPassWordForStoringInConfigFile(str, FormsAuthPasswordFormat.MD5.ToString()); }}

3.页面帮助类：PageHelper.cs

用处：向前台展示js信息时

public class PageHelper{ /// <summary> /// 读取指定路径的文件，并返回字符串格式 /// </summary> /// <param name="strPath">文件路径-物理路径 </param> /// <returns></returns> public static string ReadFile(string strPath) { return File.ReadAllText(strPath); } /// <summary> /// 获取提示和跳转js代码字符串 /// </summary> /// <param name="strMsg"></param> /// <param name="strBackUrl"></param> public static void WriteJSMsg(string strMsg, string strBackUrl) { string strBack = "<script>alert(" + strMsg + ");window.location='" + strBackUrl + "';</script>"; HttpContext.Current.Response.Write(strBack); } /// <summary> /// 跳转js代码字符串 /// </summary> /// <param name="strMsg"></param> public static void WriteJSMsg(string strMsg) { string strBack = "<script>alert(" + strMsg + ");</script>"; HttpContext.Current.Response.Write(strBack); }}

4.验证帮助类：ValidateHelper.cs

用处：对数据进行验证

public class ValidateHelper{ static Regex regIsNum=new Regex("^[0-9]+$"); /// <summary> /// 验证 参数是否为整型数值 /// </summary> /// <param name="strNum"></param> /// <returns></returns> public static bool IsNum(string strNum) { return regIsNum.IsMatch(strNum); }}

5.异步消息处理类AjaxMsgHelper.cs

用处：将需要返回的信息，以一定的内容形式返回

public static class AjaxMsgHelper{ /// <summary> /// 以json的格式返回消息 /// </summary> /// <param name="statu">状态码</param> /// <param name="msg">状态信息</param> /// <param name="data">返回数据</param> /// <param name="nextUrl">跳转url</param> public static void AjaxMsg(string statu, string msg,string data,string nextUrl) { //{"statu":"err","msg":"出错啦","data":[{},{}],"nextUrl":"Login.aspx"} string strMsg = "{\"statu\":\""+statu+"\",\"msg\":\""+msg+"\",\"data\":"+(data==null?"null":data)+",\"nextUrl\":\""+nextUrl+"\"}"; HttpContext.Current.Response.Write(strMsg); } public static void AjaxMsg(string statu, string msg, string data) { AjaxMsg(statu,msg,data,"null"); } public static void AjaxMsg(string statu, string msg) { AjaxMsg(statu,msg,null,null); }}

6.Json数据实体

用处：将需要返回的数据进行集中，并封装

/// <summary>/// Json 数据实体/// </summary>public class JsonModel{ public object Data { get; set; } public string Msg { get; set; } public string Statu { get; set; } public string BackUrl { get; set; }}
