Connecting from Code
The CData ADO.NET Provider for XML implements a standard DbConnection object in XMLConnection. You can also use the XMLConnectionStringBuilder 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 XMLConnection objects.
C#
using (XMLConnection connection =
new XMLConnection("DataModel=Relational;URI=C:\people.xml"))
{
connection.Open();
}
VB.NET
Using connection As New XMLConnection("DataModel=Relational;URI=C:\people.xml")
connection.Open
End Using
Using XMLConnectionStringBuilder
The following code example shows how to use an ADO.NET connection string builder to parse a connection string.
C#
XMLConnectionStringBuilder builder =
new XMLConnectionStringBuilder("DataModel=Relational;URI=C:\people.xml");
//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 = "DataModel=Relational;URI=C:\people.xml";
//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 XMLConnectionStringBuilder = New XMLConnectionStringBuilder("DataModel=Relational;URI=C:\people.xml")
'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 = DataModel=Relational;URI=C:\people.xml"
'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
