Connecting from Code
The CData ADO.NET Provider for AlloyDB implements a standard DbConnection object in AlloyDBConnection. You can also use the AlloyDBConnectionStringBuilder 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 AlloyDBConnection objects.
C#
using (AlloyDBConnection connection =
new AlloyDBConnection("User=alloydb;Password=admin;Database=alloydb;Server=127.0.0.1;Port=5432"))
{
connection.Open();
}
VB.NET
Using connection As New AlloyDBConnection("User=alloydb;Password=admin;Database=alloydb;Server=127.0.0.1;Port=5432")
connection.Open
End Using
Using AlloyDBConnectionStringBuilder
The following code example shows how to use an ADO.NET connection string builder to parse a connection string.
C#
AlloyDBConnectionStringBuilder builder =
new AlloyDBConnectionStringBuilder("User=alloydb;Password=admin;Database=alloydb;Server=127.0.0.1;Port=5432");
//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 = "User=alloydb;Password=admin;Database=alloydb;Server=127.0.0.1;Port=5432";
//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 AlloyDBConnectionStringBuilder = New AlloyDBConnectionStringBuilder("User=alloydb;Password=admin;Database=alloydb;Server=127.0.0.1;Port=5432")
'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 = User=alloydb;Password=admin;Database=alloydb;Server=127.0.0.1;Port=5432"
'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
