将Azure SQL数据库连接到ASP.NET项目

Question

I'm using Visual studio 2015. I have created a database on Azure and connected to it and can see it connected in the SQL Object browser.

I have copied in my connection string from the Azure dashboard and set the firewall for the database to allow any IP address access the database.

My connection string is:

static string connString = @"Server=tcp:uvaluedb2.database.windows.net,1433;Initial Catalog=UValueDB2;Persist Security Info=False;User ID=XXXXXXX;Password=XXXXXXXXX;MultipleActiveResultSets=False;Encrypt=True;TrustServerCertificate=False;Connection Timeout=30;";

It is not connecting to the database and i get this message:

Server Error in '/' Application.

A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)

I can query the database in VS.

Answer 1

I have created a database on Azure and connected to it and can see it connected in the SQL Object browser.

I had this in my firewall settings though: All 0.0.0.0 255.255.255.255.

It seems that you give access to SQL Azure database from all IP addresses, which should enable you to access SQL Azure database from your application running on local. Please make sure if you specify the correct SQL server name “ uvaluedb2 ” in your connection string. And you could get Connection string from Azure portal.

Besides, please try to create new SQL Azure database and configure firewall rules, and then access it from your application to check if same issue will appear.
