Example

The following sample shows how to execute the ExecuteMultipleRequest message.

// Get a reference to the organization service.
using (_serviceProxy = ServerConnection.GetOrganizationProxy(serverConfig))
{
    // Enable early-bound type support to add/update entity records required for this sample.
    _serviceProxy.EnableProxyTypes();
    
    #region Execute Multiple with Results
    // Create an ExecuteMultipleRequest object.
    requestWithResults = new ExecuteMultipleRequest()
    {
        // Assign settings that define execution behavior: continue on error, return responses. 
        Settings = new ExecuteMultipleSettings()
        {
            ContinueOnError = false,
            ReturnResponses = true
        },
        // Create an empty organization request collection.
        Requests = new OrganizationRequestCollection()
    };

    // Create several (local, in memory) entities in a collection. 
    EntityCollection input = GetCollectionOfEntitiesToCreate();

    // Add a CreateRequest for each entity to the request collection.
    foreach (var entity in input.Entities)
    {
        CreateRequest createRequest = new CreateRequest { Target = entity };
        requestWithResults.Requests.Add(createRequest);
    }

    // Execute all the requests in the request collection using a single web method call.
    ExecuteMultipleResponse responseWithResults =
        (ExecuteMultipleResponse)_serviceProxy.Execute(requestWithResults);

    // Display the results returned in the responses.
    foreach (var responseItem in responseWithResults.Responses)
    {
        // A valid response.
        if (responseItem.Response != null)
            DisplayResponse(requestWithResults.Requests[responseItem.RequestIndex], responseItem.Response);

        // An error has occurred.
        else if (responseItem.Fault != null)
            DisplayFault(requestWithResults.Requests[responseItem.RequestIndex], 
                responseItem.RequestIndex, responseItem.Fault);
    }

    For Each responseItem In responseWithResults.Responses

        If responseItem.Response IsNot Nothing Then
            ' A valid response.
