Custom Element Names using the DataContractSerializer on a List of primitives

由 こ雲淡風輕ζ 提交于 2021-02-04 14:52:07
问题 I'm interested about the best way to go about setting custom element names when using List of primitives with the DataContractSerializer. Let's say I have the following class which contains a List of Strings as a DataMember. [DataContract] public class ClassName { [DataMember] public List<String> FieldName { get; set; } } By default, this serializes to the following: <ClassName xmlns:i="http://www.w3.org/2001/XMLSchema-instance"> <FieldName xmlns:a="http://schemas.microsoft.com/2003/10

RabbitMQ(四):RPC的实现

由 时光总嘲笑我的痴心妄想 提交于 2021-02-02 04:52:20
一、RPC 　　RPC（Remote Procedure Call）—远程过程调用，它是一种通过网络从远程计算机程序上请求服务，而不需要了解底层网络技术的协议。有很多方式可以实现，譬如UNIX RPC、REST API、WCF和SOAP。这些传统的RPC实现方法有共同之处：那就是客户端和服务器端紧密相连，客户端直接连接上服务器，发送一个请求，然后就停下来等待服务器的应答。 　　这种点对点的性质模式有很多好处，它使得在小范围内的拓扑变得简单。但是当有众多服务器的时候，客户端如何发现在那台服务器上可以找到其他想要的服务就变的麻烦，SOAP和大多数的企业RPC已经采用复杂的补充协议和服务目录，但也带来了额外的复杂度和众多故障点。 　　但是，用RabbitMQ来实现RPC可以无需关心由那台服务器来处理，也不必担心服务器奔溃，只需要简单的发送消息，然后等待响应即可。一般接触RabbitMQ的都是用发后即忘模型，用于发送邮件等通知或者处理其他并行处理事件，也就是AMQP的消息是单向的。如何才能让服务器将处理结果返回给原始的客户端呢？ 二、消息应答和私有队列 　　RabbitMQ有一个优雅的解决方案：使用消息来发回应答。在每个AMQP消息头里有个字段 reply_to .消息的生产者可以通过该字段来确定队列的名称，并监听应答队列等待应答。然后接收消息的RPC服务器能偶检查reply_to字段

问题 Can we use simple injector for dependency injection in wcf services 回答1: We can use simple injector for dependency injection in wcf services.Here is my demo.
