Using CrmDiscoveryService Web Service To Find Sales Org and Web Service End Point

Microsoft Dynamics CRM CrmDiscoveryService Web service provides a list of Web service endpoint URLs for each sales organization that you are a member of. The following sample code shows you how to use the Web service:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

using CRMDiscoveryServices;
using System.Configuration;
using System.Text;

public partial class _Default : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        try
        {
            // Get CRM Dynamics credential from web configuration
            string crmUserId = ConfigurationManager.AppSettings["CRMUSERID"];
            string crmPassword = ConfigurationManager.AppSettings["CRMPASSWORD"];
            string crmDomain = ConfigurationManager.AppSettings["CRMDOMAIN"];

            // Create and configure the CrmDiscoveryService Web service proxy.
            CrmDiscoveryService discoveryService = new CrmDiscoveryService();
            discoveryService.Credentials = new System.Net.NetworkCredential(crmUserId, crmPassword, crmDomain);

            // Retrieve the list of organizations that the logged on user belongs to.
            RetrieveOrganizationsRequest orgRequest = new RetrieveOrganizationsRequest();
            RetrieveOrganizationsResponse orgResponse = (RetrieveOrganizationsResponse)discoveryService.Execute(orgRequest);

            // Locate the target organization in the list.
            if (orgResponse != null && orgResponse.OrganizationDetails.Length > 0)
            {
                StringBuilder sb = new StringBuilder();
                foreach (OrganizationDetail orgDetail in orgResponse.OrganizationDetails)
                {
                    sb.AppendLine("<B>Organisation name:</B> " + orgDetail.OrganizationName
                        + " <B>CRM Web application.:</B> " + orgDetail.WebApplicationUrl
                        + " <B>CrmService Web service URL:</B> " + orgDetail.CrmServiceUrl + "<BR/>");
                }
                Response.Write(sb.ToString());
            }
        }
        catch (Exception ex)
        {
            throw ex;
        }
    }
}
