示例

下面的示例演示如何使用 ReceiveContent 类指定 Receive 活动的内容。

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>)	使用指定的参数创建一个新的 ReceiveMessageContent 实例。
Create(OutArgument)	使用指定消息创建一个新的 ReceiveMessageContent 实例。
Create(OutArgument, Type)	使用指定的消息和消息类型创建新 ReceiveMessageContent 实例。
Equals(Object)	确定指定对象是否等于当前对象。 (继承自 Object)
GetHashCode()	作为默认哈希函数。 (继承自 Object)
GetType()	获取当前实例的 Type。 (继承自 Object)
MemberwiseClone()	创建当前 Object 的浅表副本。 (继承自 Object)
ToString()	返回表示当前对象的字符串。 (继承自 Object)
