示例1: Main

static void Main()
{
    // Create a new DbConnctionStringBuilder, and add items
    // to the internal collection of key/value pairs.
    DbConnectionStringBuilder builder = 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 (ArgumentException)
    {
        Console.WriteLine("Invalid connection string.");
    }

    Console.WriteLine();
    Console.WriteLine("Press Enter to finish.");
    Console.ReadLine();
}
