在我的Web应用程序中,我收到以下错误:

WebForms UnobtrusiveValidationMode需要'jquery'的ScriptResourceMapping.请添加一个名为jquery的ScriptResourceMapping(区分大小写).

描述:执行当前Web请求期间发生未处理的异常.请查看堆栈跟踪以获取有关错误及其源自代码的位置的更多信息.

异常详细信息:System.InvalidOperationException:WebForms UnobtrusiveValidationMode需要ScriptResourceMapping用于'jquery'.请添加一个名为jquery的ScriptResourceMapping(区分大小写).

我该如何解决？

我正在尝试使用 flutter_local_notifications 创建本地通知 首先，我为我的项目创建了 API 类：

class NotificationApi{
  static final FlutterLocalNotificationsPlugin _notifications = FlutterLocalNotificationsPlugin();
  static Future _notificationDetailes() async => const NotificationDetails(
    android: AndroidNotificationDetails(
      "channel id",
      "channel name",
      channelDescription: "channel description",
      importance: Importance.max,
      playSound: true
    ),
    iOS: IOSNotificationDetails(),
  );
  
  static Future showNotification({int id =0, String? title, String? body, String? payload}) async =>
      _notifications.show(id, title, body, await _notificationDetailes(), payload: payload);
}

然后我用浮动按钮触发通知：

 floatingActionButton: FloatingActionButton(
    onPressed: () {
      NotificationApi.showNotification(
          title:  "Oz Cohen",
          body: "Hey!! this is my first Notification!",
          payload: "oz.ss"
      );
    }, …

这是我的错误:

System.Data.dll中出现"System.Data.SqlClient.SqlException"类型的异常,但未在用户代码中处理

附加信息:参数化查询'(@ username nvarchar(3),@ password nvarchar

这是我的表:

CREATE TABLE [dbo].[User] 
(
    [Username]  VARCHAR (250) NOT NULL,
    [Pasword]   VARCHAR (MAX) NOT NULL,
    [FName]     VARCHAR (MAX) NOT NULL,
    [LName]     VARCHAR (MAX) NOT NULL,
    [Location]  VARCHAR (MAX) NOT NULL,
    [Profesion] VARCHAR (MAX) NOT NULL,
    [email]     VARCHAR (MAX) NOT NULL,
    [gender]    VARCHAR (MAX) NOT NULL,
    [money]     INT           NOT NULL,
    [property]  VARCHAR (MAX) NULL,

    PRIMARY KEY CLUSTERED ([Username] ASC)
);

这是C#代码:

if (Page.IsValid)
{
    SqlCommand NewUser = new SqlCommand("INSERT INTO [User] Values (@username,@password,@name,@lastname,@location,@profesion,@email,@gender,@money,@pro);", c); …
