範例
下列範例示範如何存取 ConnectionStringSettingsCollection。
static void ShowConnectionStrings()
{
// Get the application configuration file.
System.Configuration.Configuration config =
ConfigurationManager.OpenExeConfiguration(
ConfigurationUserLevel.None);
// Get the conectionStrings section.
ConnectionStringsSection csSection =
config.ConnectionStrings;
for (int i = 0; i <
ConfigurationManager.ConnectionStrings.Count; i++)
{
ConnectionStringSettings cs =
csSection.ConnectionStrings[i];
Console.WriteLine(" Connection String: \"{0}\"",
cs.ConnectionString);
Console.WriteLine("#{0}", i);
Console.WriteLine(" Name: {0}", cs.Name);
Console.WriteLine(" Provider Name: {0}",
cs.ProviderName);
}
}
Shared Sub ShowConnectionStrings()
' Get the application configuration file.
Dim config _
As System.Configuration.Configuration = _
ConfigurationManager.OpenExeConfiguration( _
ConfigurationUserLevel.None)
' Get the conectionStrings section.
Dim csSection _
As ConnectionStringsSection = _
config.ConnectionStrings
For i As Integer = 0 To ConfigurationManager.ConnectionStrings.Count - 1
Dim cs As ConnectionStringSettings = _
csSection.ConnectionStrings(i)
Console.WriteLine( _
" Connection String: ""{0}""", cs.ConnectionString)
Console.WriteLine("#{0}", i)
Console.WriteLine(" Name: {0}", cs.Name)
Console.WriteLine( _
" Provider Name: {0}", cs.ProviderName)
Next i
End Sub
