    public partial class DB_PhonebookEntities : ObjectContext
    {            
        public DB_PhonebookEntities() : base("name=DB_PhonebookEntities", "DB_PhonebookEntities")
        {            
            ....
        }

        public DB_PhonebookEntities(string connectionString): base(connectionString, "DB_PhonebookEntities") 
        {
            ....
        }

        public DB_PhonebookEntities(EntityConnection connection) : base(connection, "DB_PhonebookEntities")
        {
            ....
        }

        ....        
    }

如何将Application.StartupPath设置为我的ConnectionString？

Answer 1

我希望在应用程序路径上的数据库中创建“模型”（... \ debug \ bin \ database.mdf）

并在我的模型中使用实体！

Answer 2

将此附加到您的连接字符串。这将指向WebApplication1 \ App_Data。所以你的mdf文件应该在App_Data文件夹中

AttachDBFilename=|DataDirectory|\aspnet-WebApplication1-20141203171438.mdf

set＆＃34; Application.StartupPath＆＃34;在may app.config connectionstring中
