How to get the entity schema name list registered in your Dynamics CRM Organization using C#.

Use the following code for fetching entity list names in your console application:


  public static EntityMetadata[] GetEntities(IOrganizationService organizationService)
        {
            Dictionary attributesData = new Dictionary();
            RetrieveAllEntitiesRequest metaDataRequest = new RetrieveAllEntitiesRequest();
            RetrieveAllEntitiesResponse metaDataResponse = new RetrieveAllEntitiesResponse();
            metaDataRequest.EntityFilters = EntityFilters.Entity;

            // Execute the request.

            metaDataResponse = (RetrieveAllEntitiesResponse)organizationService.Execute(metaDataRequest);

            var entities = metaDataResponse.EntityMetadata;

            return entities;
        }

        public static void PrintEntitySchemaNames()
        {
            OrganizationServiceProxy _orgservice = CreateCrmServiceObjectOnline();
            Console.WriteLine("===================================");

            #region GivesTHeListOfAllEntitiesInAnOrganization
            var allEntities = GetEntities(_orgservice);
            foreach (EntityMetadata Entity in allEntities)
            {
                Console.WriteLine(Entity.LogicalName);
            }
            Console.WriteLine("===================================");
            Console.ReadKey();
            #endregion
        }


 public static OrganizationServiceProxy CreateCrmServiceObjectOnPremise()
        {

            OrganizationServiceProxy srvOnline = null;
            string strServerUrl = "YourServerUrl + "/" + OrgName";
            string userId = "UserName";
            string password = "passWord";
            string DomainName = "Domain";

            Uri orgUri;
            orgUri = new Uri(strServerUrl + "/XRMServices/2011/Organization.svc");

            IServiceManagement orgServiceManagement =
             ServiceConfigurationFactory.CreateManagement(orgUri);

            AuthenticationCredentials creds = new AuthenticationCredentials();
            creds.ClientCredentials.UserName.UserName = userId;
            creds.ClientCredentials.UserName.Password = password;
            AuthenticationCredentials tokenCredentials = orgServiceManagement.Authenticate(creds);

            ClientCredentials credentials = new ClientCredentials();

            credentials.Windows.ClientCredential = new System.Net.NetworkCredential(userId, password, DomainName);

            try
            {
                srvOnline = new OrganizationServiceProxy(orgUri, null, credentials, null);
            }
            catch (Exception ex)
            {
                Console.WriteLine("Error Occurs: " + ex.Message);
            }

            return srvOnline;
        }

            string UrlPrefix = string.Empty;
            string ServerUrl = string.Empty;
            string DomainName = string.Empty;
            string DomainUserId = string.Empty;
            string DomainPassword = string.Empty;

            UrlPrefix = "https://";

            }
            catch (Exception ex)

                Console.WriteLine(ex.Message.ToString());
            }
