1.添加MySql.Data.dll引用 2.SQLHelper类：private string strConn;        private MySqlConnection sqlConn;        private MySqlCommand sqlComm;        private string errMsg = null;        private

string s= "exe";            Regex reg = new Regex(@"[\u4E00-\u9FFF]+");            if (reg.IsMatch(s))                 Response.Write("有汉字");            else                Response.Write("没

1、下载并引用AjaxPro.dll2、CS:  [AjaxPro.AjaxNamespace("softintro")]    public partial class softintro : System.Web.UI.Page    {        protected void Page_Load(object sender, EventArgs e)

说明：上传控件没有用ASP.NET自带的FileUpload控件，用的第三方控件：Brettle.Web.NeatUpload.dll 步骤：1.添加  Brettle.Web.NeatUpload.dll 引用2.aspx:                                

1、SQL查询，返回DataTable2、ViewState["WEA"] =返回的DataTable数据（dt）;      GridView1.DataSource= dt;      GridView1.DataBind();3、protected void GridView1_PageIndexChanging(object sender, GridViewPageEven

aspx:        font-size: 15px; color: Gray;">        共                条   共                页                         

XmlDocument xmlDoc = new XmlDocument();xmlDoc.Load(Server.MapPath("CNCity.xml"));XmlNodeList nodeList = xmlDoc.SelectSingleNode("resources").ChildNodes;//获取resources节点的所有子节点DataTable dts = nul

DataTable  dts=null; DataTable  d=bcn.GetAll(); if(dts==null){//如果需要累计复制就要有此判断，否则后面的数据会把前面的数据覆盖掉   dts=d.Clone();} if(d.Rows.Count>0){DataRow dr=d.Rows[0];dts.ImportRow(dr);}

cs:public string FormatState(string state)        {            if (state == "2")            {                return "1";            }            else             {                ret

aspx:cs://抓取内容try        {            WebRequest request = WebRequest.Create("http://www.baidu.com/");            WebResponse response = request.GetResponse();            StreamReader

string s = System.Web.HttpContext.Current.Request.Url.ToString();  s = s.Substring(0, s.LastIndexOf('/'));   this.downurl.Value = s +"/"+ dtinfo.Rows[0]["DownUrl"].ToString();

ImportCSV类：public class ImportCSV    {        private string path;        private string fileName;        public ImportCSV(string filePath, string fileName)//构造函数        {            thi

string filepath = Request.PhysicalPath;   filepath = filepath.Substring(0, filepath.LastIndexOf('\\'));//测试 filepath = filepath.Substring(0, filepath.LastIndexOf('\\')) + "\\test\\" + DateTime.Now

ddlDepar.DataBind();ddlDepar.Items.Insert(0, new ListItem("---请选择---", "0"));

public void ExportCSV() {            Test users = new Test();            DataTable dt = users.GetAll();//测试方法            try            {                StringWriter swCSV = new StringWriter

1.添加Excel引用 2. protected void Page_Load(object sender, EventArgs e)        {            if (!IsPostBack)            {                Outputexecl(sender, e);                     }

asp.net 项目，在生成解决方法过程中，出现“Files 的值"***"”解决方案生成失败。解决：例：项目名称为：ABC在项目目录下的“ABC\obj\Debug\”的文件夹中找到与项目同名的“.csproj.FileListAbsolute.txt”文件，即“ABC.csproj.FileListAbsolute.txt”，打开后会看到部分文字乱码，删除掉乱码部分，保存，重新
