将ASP.Net应用程序从Web连接到计算机上的sql数据库

Question

I am creating two applications: An ASP.Net application and a C# application. I used SQL Server as the database. My ASP.Net application should connect to the internet but the database should only be on my computer. I used connectionString to connect my two applications in just one database (SQL). Is there a way to connect my ASP.Net application from the web to my SQL database on my computer?

I've read lots of tutorial but I can't find the solution.

Answer 1

Ordinary SQL Server is local to to the Web application (it's either located on the same LAN or sometimes even on the same machine).

Technically it is possible to connect an ASP.NET application to a remote SQL server, but it is not recommended, you can open a can of worms there (problems with firewalls, ports, performance etc.)

Answer 2

Here's my solution for that:

1. Make sure you have a static IP address assigned by the ISP.
2. Make sure that you assign a static IP address in your computer.
3. Now, use "Port Forwarding" technique. Configure your router to forward the packets from port 1433 going to your computer.
4. The next thing you do is you configure or modify your web.config (ASP.NET file) that is deployed outside your network (in a hosting company) and make sure that the datasource of your connectionString looks something like this: connectionString="data source=214.23.12.21 (where 214.23.12.21 is the static public IP assigned to you by your ISP).
