return new Sequence
{
    Variables = { po, customer },
    Activities =
    {
        new Assign<PurchaseOrder>
        {
            To = po,
            Value = new InArgument<PurchaseOrder>( (e) => new PurchaseOrder() { PartName = "Widget", Quantity = 150 } )
        },
        new Assign<Customer>
        {
            To = customer,
            Value = new InArgument<Customer>( (e) => new Customer() { Id = 12345678, Name = "John Smith" } )
        },
        new WriteLine { Text = new InArgument<string>( (e) => string.Format("Submitting new PurchaseOrder for {0} {1}s", po.Get(e).Quantity, po.Get(e).PartName) ) },
        new CorrelationScope
        {
            Body = new Sequence
            {
                Activities =
                {
                    submitPO,
                    new ReceiveReply
                    {
                        Request = submitPO,
                        Content = ReceiveContent.Create(new OutArgument<int>( (e) => po.Get(e).Id ))
                    }
                }
            }
        },
        new WriteLine { Text = new InArgument<string>( (e) => string.Format("Received ID for new PO: {0}", po.Get(e).Id) ) },
        new Assign<int> { To = new OutArgument<int>( (e) => po.Get(e).Quantity ), Value = 250 },
        new WriteLine { Text = "Updated PO with new quantity: 250.  Resubmitting updated PurchaseOrder based on POId." },
        new Send
        {
            Endpoint = clientEndpoint,
            ServiceContractName = Constants.POContractName,
            OperationName = Constants.UpdatePOName,
            Content = SendContent.Create(new InArgument<PurchaseOrder>(po))
        },
        new Assign<int>
        {
            To = new OutArgument<int>( (e) => po.Get(e).CustomerId ),
            Value = new InArgument<int>( (e) => customer.Get(e).Id )
        },
        new WriteLine { Text = "Updating customer data based on CustomerId." },
        new Send
        {
            Endpoint = clientEndpoint,
            ServiceContractName = Constants.POContractName,
            OperationName = Constants.AddCustomerInfoName,
            Content = SendContent.Create(new InArgument<PurchaseOrder>(po))
        },
        new Send
        {
            Endpoint = clientEndpoint,
            ServiceContractName = Constants.POContractName,
            OperationName = Constants.UpdateCustomerName,
            Content = SendContent.Create(new InArgument<Customer>(customer))
        },
        new WriteLine { Text = "Client completed." }
    }
};

方法

Create(IDictionary<String,OutArgument>)	使用指定的參數，建立新的 ReceiveMessageContent 執行個體。
Create(OutArgument)	使用指定的訊息，建立新的 ReceiveMessageContent 執行個體。
Create(OutArgument, Type)	使用指定的訊息和訊息型別，建立新的 ReceiveMessageContent 執行個體。
Equals(Object)	判斷指定的物件是否等於目前的物件。 (繼承來源 Object)
GetHashCode()	做為預設雜湊函式。 (繼承來源 Object)
GetType()	取得目前執行個體的 Type。 (繼承來源 Object)
MemberwiseClone()	建立目前 Object 的淺層複製。 (繼承來源 Object)
ToString()	傳回代表目前物件的字串。 (繼承來源 Object)
