String conn = () įrom the following links you can see how each dataprovider makes connection to the database from ASP.NET application. You can access the connectionstring value at run time in your ASP.NET application as shown in the following example.ĭim conn As String = ConfigurationManager.ConnectionStrings("SQLDbConnection") You can create connectionStrings element within the Element element, by create a child element named and place your connection strings there. You can store connection strings in the Web.config file and reference the configuration entries in data source controls. "Dbq=c:\path\pub.mdb Exclusive=1 Uid=Admin Pwd=password "

NET Core class library and we will use a Microsoft SQL Server Database Provider named ''. NET DataProvider - Standard ConnectionĬonnectionString = "Data Source=servername " + In this session, we will connect to a SQL Server Database from a. NET Framework provides mainly three data providers, they areįrom the following section you can find different types of providers and its connection strings in detail.
Usually Data Providers use a connection string containing a collection of parameters to establish the connection with the database through applications. The Connection String includes parameters such as the name of the driver, Server name and Database name, as well as security information such as user name and password.Īn ADO.NET Data Provider is a class that can communicate with a specific type of database or data store. It contains the parameters such as server name, database name, and the name of the driver. Services.A connection string provides the information that a provider needs to communicate with a particular database. The connection string is required for the application to establish a connection to the database. File > New project > ASP.NET Core Web Application Enter solution name: OrdersViewer Select Web API. Public void ConfigureServices(IServiceCollection services) Well kick things off by creating a new Web API project. Add Connection Stringįor this example we're going to use SQLite in memory mode, for production you'll want to use something else, but it's pretty easy to change.įirst you want to add the connection string to, something like this: A public constructor that accepts LinqToDbConnectionOptions and passes the options on to the base constructor is required.
