The CData ADO.NET Provider for Microsoft Access implements a standard DbConnection object in AccessConnection. You can also use the AccessConnectionStringBuilder to programmatically build, parse, and rebuild connection strings.

Creating Connection Objects

See Establishing a Connection for guides to defining the connection string and authenticating. Below is a typical invocation to create AccessConnection objects.

C#

using (AccessConnection connection =   
  new AccessConnection("DataSource=C:\\My.accdb"))  
{  
  connection.Open();  
}

VB.NET

Using connection As New AccessConnection("DataSource=C:\\My.accdb")
  connection.Open
End Using

Using AccessConnectionStringBuilder

The following code example shows how to use an ADO.NET connection string builder to parse a connection string.

C#

AccessConnectionStringBuilder builder =
  new AccessConnectionStringBuilder("DataSource=C:\\My.accdb");
  //Pass the connection string builder an existing connection string, and you can get and set any of the elements as strongly typed properties.
  builder.ConnectionString = "DataSource=C:\\My.accdb";
  //Now that the connection string has been parsed,
  // you can work with individual items:
  builder.MyString = "new property";
  builder.MyBoolean = true;

  // You can refer to connection keys using strings, 
  // as well. 
  builder["Logfile"] = "test.log";
  builder["Verbosity"] = 5;

VB.NET

Dim builder As AccessConnectionStringBuilder = New AccessConnectionStringBuilder("DataSource=C:\\My.accdb")
'Pass the connection string builder an existing connection string, and you can get and set any of the elements using strongly typed properties.
builder.ConnectionString = DataSource=C:\\My.accdb"
'Now that the connection string has been parsed,
' you can work with individual items:
builder.MyString = "new property"
builder.MyBoolean = True
  
' You can refer to connection keys using strings, 
' as well. 
builder("Logfile") = "test.log"
builder("Verbosity") = 5
