实验二 Web服务器控件实验报告

WEB 应用开发 WEB 服务器控件实验报告实验2-1 使用FileUpLoad 控件上传文件 任务清单创建一个WEB 窗体，实现界面效果如下：提示：string fileName = FileUpload1.FileName;//得到文件名float fileSize = FileUpload1.FileBytes.Length;//得到文件长度string ext = System.IO.Path .GetExtension(fileName);//得到文件扩展名string filePath = FileUpload1.PostedFile.FileName;//得到文件在客户端的路径 txtFileUploadPath.Text = Server.MapPath(".");//得到当前站点的物理路径FileUpload1.SaveAs(Server.MapPath(".") + "/Upload/"+fileName);//文件存到服务器上 学 号090201124 姓 名 李晓晖 专业、班 计科09-1 学 期2011-2012 第2学期 指导教师 黄俊莲 实验地点C 区二层机房 机 器 号 时 间 2012年 月 日 周 节实验任务清单 1. 实验2-1 使用FileUpLoad 控件上传文件2. 实验2-2 Calendar 控件的使用13. 实验2-3 Calendar 控件的使用2实验要求注意：本次实验要求创建一个网站，名称命名规则为“学号_姓名_HomeWork1”，如：“090201201_戚琦_ HomeWork2”，“实验2-1”至“实验2-5”页面都在此网站中添加。
