Connecting from Code

The CData ADO.NET Provider for Oracle implements a standard DbConnection object in OracleOciConnection. You can also use the OracleOciConnectionStringBuilder 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 OracleOciConnection objects.

using (OracleOciConnection connection =   
  new OracleOciConnection("User=scott;Password=tiger;Server=127.0.0.1;Port=1521;"))  
{  
  connection.Open();  
}

VB.NET

Using connection As New OracleOciConnection("User=scott;Password=tiger;Server=127.0.0.1;Port=1521;")
  connection.Open
End Using

Using OracleOciConnectionStringBuilder

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

OracleOciConnectionStringBuilder builder =
  new OracleOciConnectionStringBuilder("User=scott;Password=tiger;Server=127.0.0.1;Port=1521;");
  //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=scott;Password=tiger;Server=127.0.0.1;Port=1521;";
  //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 OracleOciConnectionStringBuilder = New OracleOciConnectionStringBuilder("User=scott;Password=tiger;Server=127.0.0.1;Port=1521;")
'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=scott;Password=tiger;Server=127.0.0.1;Port=1521;"
'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
