在一个典型的ASP.NET web应用中,我们可以通过以下步骤实现用户认证和数据处理功能。以下是基于代码的详细说明:
admin = Context.Request.Cookies["user"].Values["username"].ToString();
Hashtable hash = new Hashtable();hash.Add("p2", admin);hash.Add("p_state", 2);
DataSet ds = Bll.ProjectInfoBll.SelectAll_state(hash) as DataSet;
Repeater1.DataSource = Bll.ProjectInfoBll.SelectAll_state(hash);this.Repeater1.DataBind();
string strnum = DateTime.Now.ToString("F");// 生成Excel文件HttpResponse response = Page.Response;response.Clear();response.Buffer = true;response.Charset = "utf-8";// 设置文件编码和字符集,确保文件正确显示response.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312");response.ContentType = "application/ms-excel";response.AppendHeader("Content-Disposition", "attachment;filename=" + HttpUtility.UrlEncode(strnum, System.Text.Encoding.UTF8) + ".xls");
System.Globalization.CultureInfo myCI = new System.Globalization.CultureInfo("ZH-CN", true);System.IO.StringWriter oStringWriter = new System.IO.StringWriter(myCI);System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter);Repeater1.RenderControl(oHtmlTextWriter);response.Write(oStringWriter.ToString());
通过以上步骤,我们可以实现用户认证、数据处理、Excel文件导出等功能,确保程序逻辑清晰,数据传输准确。
