示例1: Main
Sub Main()
' Create a new DbConnctionStringBuilder, and add items
' to the internal collection of key/value pairs.
Dim builder As New DbConnectionStringBuilder()
builder.Add("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)
' Display the contents of the connection string, which
' will now contain all the key/value pairs delimited with
' semicolons.
Console.WriteLine(builder.ConnectionString)
Console.WriteLine()
' Clear the DbConnectionStringBuilder, and assign a complete
' connection string to it, to demonstrate how
' the class parses connection strings.
builder.Clear()
builder.ConnectionString = _
"Data Source=(local);Initial Catalog=AdventureWorks;" & _
"Integrated Security=SSPI"
' The DbConnectionStringBuilder class has parsed the contents,
' so you can work with any individual key/value pair.
builder("Data Source") = "."
Console.WriteLine(builder.ConnectionString)
Console.WriteLine()
' Because the DbConnectionStringBuilder class doesn't
' validate its key/value pairs, you can use this class
' to store any semicolon-delimited list. The following
' snippet places an arbitrary string into the ConnectionString
' property, changes one of the values, and then displays the
' resulting string.
builder.Clear()
builder.ConnectionString = _
"Value1=10;Value2=20;Value3=30;Value4=40"
builder("Value2") = 25
Console.WriteLine(builder.ConnectionString)
Console.WriteLine()
builder.Clear()
Try
' Assigning an invalid connection string
' throws an ArgumentException.
builder.ConnectionString = "xxx"
Catch ex As ArgumentException
Console.WriteLine("Invalid connection string.")
End Try
Console.WriteLine()
Console.WriteLine("Press Enter to finish.")
Console.ReadLine()
