We may want to consider other approaches when our use cases become more involved or find reusable patterns emerging in our code base. Once you store XML data, you then can perform operations such as querying or updating it from ADO.NET 2.0, XML indexing, executing queries using a new XQuery language, and so on. For straightforward scenarios, ADO.NET is a capable and enjoyable method for data access. SQL Server 2005 will feature a native XML data type that will allow you to store native XML data in SQL Server itself. Mapping the results to our C# models is our responsibility, and can be tedious.ĪDO.NET assumes very little for us, and it is the lowest level approach to data access available to. When executing a SQL query, we can read any results via a DbDataReader. With SqlCommand, we can run text, stored procedures, and table direct queries. ado.net sql connection string example, ado.net connection string username password ADO.NET connection string c example In this tutorial you will learn about DbConnection methods and how to setup ConnectionString property in ado. We can perform operations through the DbCommand implementation.

The class allows us to pass commands and read results from a database. The SQL Server implementations of these classes are SqlConnection, SqlCommand, and SqlDataReader.ĭata access code with ADO.NET always starts with an open database connection. These sample connection strings are compiled by Carl Prothman, a Microsoft ASP.NET MVP and Microsoft Certified Professional (MCP) If you have an ADO or ADO. There are three commonly used objects in ADO.NET that developers will deal with: DbConnection, DbCommand, and DbDataReader. Also included are ADO.NET connection strings for MySQL, ODBC, OLE DB, Oracle, and SQL Server. ADO.NET is a low-level interface to our data storage of choice, and its use depends heavily on our understanding of SQL. More recently, the ADO.NET libraries ship in NuGet packages, with being specifically for SQL Server access.

NET framework, Microsoft packaged it along with other libraries.
