上传并保存excel 使用FileUpload（asp控件）
string strName = FileUpload1.PostedFile.FileName;//使用fileupload控件获取上传文件的文件名 if (strName != "")//如果文件名存在 { bool fileOK = false; int i = strName.LastIndexOf(".");//获取。的索引顺序号，在这里。代表图片名字与后缀的间隔 string kzm = strName.Substring(i);//获取文件扩展名的另一种方法 string fileExtension = System.IO.Path.GetExtension(FileUpload1.FileName).ToLower(); string newName = Guid.NewGuid().ToString();//生成新的文件名，保证唯一性 string xiangdui = @"~\AssetsManager\upload\";//设置文件相对网站根目录的保存路径 ，~号表示当前目录，在此表示根目录下的images文件夹 string juedui = Server.MapPath("~\\AssetsManager\\upload\\");//设置文件保存的本地目录绝对路径，对于路径中的字符“＼”在字符串中必须以“＼＼”表示，因为“＼”为特殊字符。或者可以使用上一行的给路径前面加上＠ string newFileName = juedui + newName + kzm; if (FileUpload1.HasFile)//验证 FileUpload 控件确实包含文件 { String[] allowedExtensions = { ".xls", ".xlsx" }; for (int j = 0; j < allowedExtensions.Length; j++) { if (kzm == allowedExtensions[j]) { fileOK = true; } } } if (fileOK) { try { // 判定该路径是否存在 if (!Directory.Exists(juedui)) Directory.CreateDirectory(juedui); // 1.文件上传 FileUpload1.PostedFile.SaveAs(newFileName); UpdateInfo(newFileName);// 更新 Page.RegisterStartupScript(Guid.NewGuid().ToString(), "<script>window.parent.$.weeboxs.close();</script>"); } catch (Exception ex) { MessageBox.show(this, "上传文件失败！", ""); } } else { MessageBox.show(this, "只能够上传.xls .xlsx格式的文件！", ""); } } else { MessageBox.show(this, "请上传文件！", ""); }上传并保存excel 使用HTML控件
