Connecting from Code
The CData ADO.NET Provider for Amazon DynamoDB implements a standard DbConnection object in AmazonDynamoDBConnection. You can also use the AmazonDynamoDBConnectionStringBuilder 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 AmazonDynamoDBConnection objects.
C#
using (AmazonDynamoDBConnection connection =
new AmazonDynamoDBConnection("AWS Access Key=xxx;AWS Secret Key=xxx;Domain=amazonaws.com;AWS Region=OREGON;"))
{
connection.Open();
}
VB.NET
Using connection As New AmazonDynamoDBConnection("AWS Access Key=xxx;AWS Secret Key=xxx;Domain=amazonaws.com;AWS Region=OREGON;")
connection.Open
End Using
Using AmazonDynamoDBConnectionStringBuilder
The following code example shows how to use an ADO.NET connection string builder to parse a connection string.
C#
AmazonDynamoDBConnectionStringBuilder builder =
new AmazonDynamoDBConnectionStringBuilder("AWS Access Key=xxx;AWS Secret Key=xxx;Domain=amazonaws.com;AWS Region=OREGON;");
//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 = "AWS Access Key=xxx;AWS Secret Key=xxx;Domain=amazonaws.com;AWS Region=OREGON;";
//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 AmazonDynamoDBConnectionStringBuilder = New AmazonDynamoDBConnectionStringBuilder("AWS Access Key=xxx;AWS Secret Key=xxx;Domain=amazonaws.com;AWS Region=OREGON;")
'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 = AWS Access Key=xxx;AWS Secret Key=xxx;Domain=amazonaws.com;AWS Region=OREGON;"
'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
