Connecting from Code

The CData ADO.NET Provider for SAP Gateway implements a standard DbConnection object in SAPGatewayConnection. You can also use the SAPGatewayConnectionStringBuilder 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 SAPGatewayConnection objects.

using (SAPGatewayConnection connection =   
  new SAPGatewayConnection("InitiateOAuth=GETANDREFRESH;User=user;Password=password;URL=https://sapes5.sapdevcenter.com/sap/opu/odata/IWBEP/GWSAMPLE_BASIC/"))  
{  
  connection.Open();  
}

VB.NET

Using connection As New SAPGatewayConnection("InitiateOAuth=GETANDREFRESH;User=user;Password=password;URL=https://sapes5.sapdevcenter.com/sap/opu/odata/IWBEP/GWSAMPLE_BASIC/")
  connection.Open
End Using

Using SAPGatewayConnectionStringBuilder

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

SAPGatewayConnectionStringBuilder builder =
  new SAPGatewayConnectionStringBuilder("InitiateOAuth=GETANDREFRESH;User=user;Password=password;URL=https://sapes5.sapdevcenter.com/sap/opu/odata/IWBEP/GWSAMPLE_BASIC/");
  //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 = "InitiateOAuth=GETANDREFRESH;User=user;Password=password;URL=https://sapes5.sapdevcenter.com/sap/opu/odata/IWBEP/GWSAMPLE_BASIC/";
  //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 SAPGatewayConnectionStringBuilder = New SAPGatewayConnectionStringBuilder("InitiateOAuth=GETANDREFRESH;User=user;Password=password;URL=https://sapes5.sapdevcenter.com/sap/opu/odata/IWBEP/GWSAMPLE_BASIC/")
'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 = InitiateOAuth=GETANDREFRESH;User=user;Password=password;URL=https://sapes5.sapdevcenter.com/sap/opu/odata/IWBEP/GWSAMPLE_BASIC/"
'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
