Posted 2023-03-21

protected void btn_login_Click(object sender, EventArgs e) string strUserName = this.txt_name.Text.Trim(); string strUserPass = this.txt_pass.Text.Trim(); int strUserType = this.drop.SelectedIndex; if (strUserName == null || "".Equals(strUserName.Trim())) Response.Write("<script>alert('请您填写您的登录账号!')</script>"); else if (strUserPass == null || "".Equals(strUserPass.Trim())) Response.Write("<script>alert('请您填写您的登录密码!')</script>"); else if (CatalogAccess.ValidateUser(strUserName, strUserPass, strUserType)) Session["UserName"] = strUserName; Session["UserPass"] = strUserPass; Session["UserType"] = strUserType; int Loginuser_id = CatalogAccess.GetUserIdByUserName(Session["UserName"].ToString()); DateTime Login_time = DateTime.Now; string Login_ip; if (System.Web.HttpContext.Current.Request.ServerVariables["HTTP_VIA"] != null) Login_ip = System.Web.HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"].ToString(); else Login_ip = System.Web.HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"].ToString(); Logininfor SingleLogin = new Logininfor(); SingleLogin.Loginuser_id = Loginuser_id; SingleLogin.Login_time = Login_time; SingleLogin.Login_ip = Login_ip; if (Logininfor.AddLogininfor(SingleLogin)) if (strUserType == 0) Response.Redirect("Default.aspx"); else if (strUserType == 1) Response.Redirect("Koimymanger/Default.aspx"); else Response.Redirect("Oooops.aspx"); else Response.Write("<script>alert('您的登录用户名和密码错误！')</script>");

程序中将date类型转换一下,转换成字符串,同时数据库中的字段也要注意格式为varchar.我记得C#中应该有数据类型是日期对应SQLSERVER中的字段中的日期类型的 参考技术A asp.net提示使用的 SQL Server 版本不支持数据类型“date”

已经提示出来了。
看看你sql表里面的字段，是不是有的字段数据类型不正确
