How to get the connection String from a database

Question

I want to use the database I generated with SQL Server Management Studio in my C# program. The connection string is what I require. Where is my database kept, and where can I get the connection string?

Is it in my papers somewhere, or do I have to publish it or something similar?

using (var conn = new SqlConnection("your connection string to the database"))

I want to get the connection string, but how? Where can I get the connection string that I need to copy and paste into the aforementioned section?

How can I make my database publishable so that Visual Studio can use it? The connection string can then be removed from there, right?

Using the "Server Explorer" window in Visual Studio (menu View, Server Explorer) and connecting to the server from that window is the simplest approach to obtain the connection string. After selecting the connection and pressing F4 or Alt+Enter or selecting Properties from the right-click menu, you can view the connection string in the linked server's properties.

Advanced connection string options can be changed while creating the connection by selecting the "Advanced..." button at the bottom of the "Add connection" window. These options include MARS, resilience, timeot, pooling configuration, and others. Later, by selecting "Modify connection..." from the context menu when right-clicking the Data Connection, you can view this dialogue. By server type, several advanced options are accessible.

If you create the database using SQL Server Management Studio, it will be created in a server instance; as a result, you will need to create a backup of the database and deploy it in the deployment SQL Server in order to deploy your application. You may also use a data file created using SQL Server Express (localDB in SQL Server 2012), which is simple to share along with your app.

For example, there is an App Datafolder if it is an ASP.NET app. You can add a new element, such as a SQL Server database, by right-clicking it. That folder will include this file, which is simple to deploy and compatible with SQL Express. For this to function, you must have localDB and SQL Express installed on your computer.
