How to: Bracket Data Submissions by Using Transactions (LINQ to SQL)

You can use TransactionScope to bracket your submissions to the database. For more information, see Transactions (LINQ to SQL).

Example

The following code encloses the database submission in a TransactionScope.

Dim db As New Northwnd("c:\northwnd.mdf")
Using ts = New TransactionScope()
    Try 

        Dim prod1 = db.Products.First(Function(p) p.ProductID = 4)
        Dim prod2 = db.Products.First(Function(p) p.ProductID = 5)
        prod1.UnitsInStock -= 3
        prod2.UnitsInStock -= 5
        db.SubmitChanges()

    Catch e As Exception
        Console.WriteLine(e.Message)
    End Try 
End Using
Northwnd db = new Northwnd(@"c:\northwnd.mdf");
using (TransactionScope ts = new TransactionScope())
{
    try
    {
        Product prod1 = db.Products.First(p => p.ProductID == 4);
        Product prod2 = db.Products.First(p => p.ProductID == 5);
        prod1.UnitsInStock -= 3;
        prod2.UnitsInStock -= 5;
        db.SubmitChanges();
    }
    catch (Exception e)
    {
        Console.WriteLine(e.Message);
    }
}
