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();
