項目中常用類

1.分頁數據模型：PagedDataModel.cs

用處：將分頁的數據，封裝到類中

public class PagedDataModel<T>{    /// <summary>    /// 總頁數    /// </summary>    public int PageCount;    /// <summary>    /// 總行數    /// </summary>    public int RowCount;    /// <summary>    /// 當前頁碼    /// </summary>    public int PageIndex;    /// <summary>    /// 當前頁碼數據    /// </summary>    public IList<T> PagedList;}

2.數據幫助類：DataHelper.cs

用處：對數據進行處理，以一定格式返回

public static class DataHelper{    /// <summary>    /// js序列化器    /// </summary>    static  javaScriptSerializer jss=new JavascriptSerializer();    /// <summary>    /// 將對象轉換為json數組格式字符串     /// </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.頁面幫助類：PageHelper.cs

用處：向前臺展示js信息時

public class PageHelper{    /// <summary>    /// 讀取指定路徑的文件，并返回字符串格式     /// </summary>    /// <param name="strPath">文件路徑-物理路徑 </param>    /// <returns></returns>    public static string ReadFile(string strPath)    {        return File.ReadAllText(strPath);    }    /// <summary>    /// 獲取提示和跳轉js代碼字符串    /// </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>    /// 跳轉js代碼字符串    /// </summary>    /// <param name="strMsg"></param>    public static void WriteJSMsg(string strMsg)    {        string strBack = "<script>alert(" + strMsg + ");</script>";        HttpContext.Current.Response.Write(strBack);    }}

4.驗證幫助類：ValidateHelper.cs

用處：對數據進行驗證

public class ValidateHelper{    static Regex regIsNum=new Regex("^[0-9]+$");    /// <summary>    /// 驗證 參數是否為整型數值    /// </summary>    /// <param name="strNum"></param>    /// <returns></returns>    public static bool IsNum(string strNum)    {        return regIsNum.IsMatch(strNum);    }}

5.異步消息處理類AjaxMsgHelper.cs

用處：將需要返回的信息，以一定的內容形式返回

public static class AjaxMsgHelper{    /// <summary>    /// 以json的格式返回消息    /// </summary>    /// <param name="statu">狀態碼</param>    /// <param name="msg">狀態信息</param>    /// <param name="data">返回數據</param>    /// <param name="nextUrl">跳轉url</param>    public static void AjaxMsg(string statu, string msg,string data,string nextUrl)    {        //{"statu":"err","msg":"出錯啦","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數據實體

用處：將需要返回的數據進行集中，并封裝

/// <summary>/// Json 數據實體/// </summary>public class JsonModel{    public object Data { get; set; }    public string Msg { get; set; }    public string Statu { get; set; }    public string BackUrl { get; set; }}
