What are the properties inside LoginScopeHeader in Salesforce?

Hi,

LoginScopeHeader
Specifies your organization ID so that you can authenticate Self-Service users for your organization using the existing login().

Example -

/// Demonstrates how to set the LoginScopeHeader values.
public void LoginScopeHeaderSample()
{
// Web Reference to the imported Partner WSDL.
APISamples.partner.SforceService partnerBinding;

string username = "USERNAME";
string password = "PASSWORD";

// The real Client ID will be an API Token provided by salesforce.com
// to partner applications following a security review. For more details,
// see the Security Review FAQ in the online help.
string clientId = "SampleCaseSensitiveToken/100";

partnerBinding = new SforceService();
partnerBinding.CallOptionsValue = new CallOptions();
partnerBinding.CallOptionsValue.client = clientId;

// To authenticate Self-Service users, we need to set the OrganizationId
// in the LoginScopeHeader.
string orgId = "00ID0000OrgFoo";
partnerBinding.LoginScopeHeaderValue = new LoginScopeHeader();
partnerBinding.LoginScopeHeaderValue.organizationId = orgId;
// Specify the Portal ID if the user is a Customer Portal user.
string portalId = "00ID0000FooPtl";
partnerBinding.LoginScopeHeaderValue.portalId = portalId;

try
{
APISamples.partner.LoginResult lr =
partnerBinding.login(username, password);
}
catch (SoapException e)
{
Console.WriteLine(e.Code);
Console.WriteLine(e.Message);
}
}

Hope this helps.
