推荐答案

1.您只需在程序文件文件夹中的数据库上单击鼠标右键，然后选择属性.在其中，取消选中readonly属性.这应该够了吧.

2.避免保留作为关键字的Db名称. "New"也不是一个有意义的名称.

3.要在设置中包含数据库，请查看以下内容:
创建设置并支持使用VS.NET创建数据库 [在安装.NET应用程序期间创建数据库 [部署您的应用程序和数据库 [

1. You can simply right click the database in program files folder and select properties. In it, uncheck the readonly property. That should do the trick.

2. Avoid keeping names of Db that are keywords. Nor does ''New'' is a meaningful name.

3. For including database in setup, have a look at these:
Creating setup With support for database creation Using VS.NET[^]
Create database during installation of a .NET application [^]
Deploy your Application and Database[^]
