An example of an AI chatbot conversation about C# LINQ to SQL data mapping techniques.
How can I use LINQ to SQL for data mapping in C#?
You can use LINQ to SQL to map your C# classes to database tables. Start by creating a DataContext class that represents your database.
What are the steps to create a DataContext class?
First, add a LINQ to SQL class to your project. Then, drag your database tables onto the designer to generate the DataContext.
Can you show me an example of querying data using LINQ to SQL?
Sure! You can use a query like var results = from c in context.Customers where c.City == "London" select c; to get customers from London.
What if I want to insert new data into the database?
You can create a new instance of your entity, set its properties, and then call context.Customers.InsertOnSubmit(newCustomer); followed by context.SubmitChanges();.
