示例1: Main
Sub Main()
Dim builder As New DbConnectionStringBuilder()
builder.ConnectionString = "Data Source=c:\MyData\MyDb.mdb"
builder.Add("Provider", "Microsoft.Jet.Oledb.4.0")
builder.Add("Jet OLEDB:Database Password", "*******")
builder.Add("Jet OLEDB:System Database", _
"c:\MyData\Workgroup.mdb")
' Set up row-level locking.
builder.Add("Jet OLEDB:Database Locking Mode", 1)
' Note that the DbConnectionStringBuilder class
' is database agnostic, and it's possible to
' build any type of connection string using
' this class.
' Notice that the ConnectionString property may have been
' formatted by the DbConnectionStringBuilder class.
Dim oledbConnect As New _
OleDbConnection(builder.ConnectionString)
Console.WriteLine(oledbConnect.ConnectionString)
' Use the same DbConnectionStringBuilder to create
' a SqlConnection object.
builder.Clear()
builder.Add("integrated security", True)
builder.Add("Initial Catalog", "AdventureWorks")
builder.Add("Data Source", "(local)")
Dim sqlConnect As New SqlConnection(builder.ConnectionString)
Console.WriteLine(sqlConnect.ConnectionString)
' Pass the DbConnectionStringBuilder an existing
' connection string, and you can retrieve and
' modify any of the elements.
builder.ConnectionString = _
"server=(local);user id=*******;" & _
"password=*******;initial catalog=AdventureWorks"
builder.Item("Server") = "."
builder.Remove("User ID")
' Note that calling Remove on a nonexistent item doesn't
' throw an exception.
builder.Remove("BadItem")
' The Item property is the default for the class,
' and setting the Item property adds the value if
' necessary.
builder("Integrated Security") = True
builder.Remove("password")
builder.Item("User ID") = "Hello"
Console.WriteLine(builder.ConnectionString)
Console.WriteLine("Press Enter to finish.")
Console.ReadLine()
