Dynamics CRM 用代码注册Plugin Step

平时我们开发时，插件的注册要么通过工具，要么通过SDK提供的VS组件，注册完插件还需要添加步骤等，那如果碰到根据业务需要灵活配置step时，再去通过工具添加或者删除就不大友好了，最好能在界面上进行可视化的操作。

本篇要分享的场景是自动编号中，每增加一条实体配置时，点击页面上的安装就能自动创建插件step，而不用手工去工具中添加

下面开始上代码，在正式创建前会有一些代码块来获取一些必需的参数

首先是获取assembly的id，这是决定你要在哪个assembly下附加

 QueryExpression query = new QueryExpression("pluginassembly");
            query.ColumnSet = new ColumnSet("pluginassemblyid");
            query.Criteria.AddCondition("name", ConditionOperator.Equal, "NY_AutoNumber");
            EntityCollection collection = organizationServiceProxy.RetrieveMultiple(query);
            string assemblyid = collection.Entities[0].Id.ToString();

然后是typeid,这个决定你的step挂在哪个plugin下面，这里有个condition参数typename，初看之下可能并不知道是什么，看下我红框中框出来的和我代码中的名字对应下就看出来了

 //get plugin types  within assembly
            query = new QueryExpression("plugintype");
            query.ColumnSet = new ColumnSet("plugintypeid");//
            query.Criteria.AddCondition("pluginassemblyid", ConditionOperator.Equal, assemblyid);
            query.Criteria.AddCondition("typename", ConditionOperator.Equal, "NY_AutoNumber.CRM.Plugins.AutoNumber");
            collection = organizationServiceProxy.RetrieveMultiple(query);
            string pluginTypesId = collection.Entities[0].Id.ToString();

然后是sdkmessageid,我这里用的是Create, 可以根据业务灵活设置name

 //GetSdkMessageId
            query = new QueryExpression("sdkmessage");
            query.ColumnSet = new ColumnSet("sdkmessageid");
            query.Criteria.AddCondition("name", ConditionOperator.Equal, "Create");
            collection = organizationServiceProxy.RetrieveMultiple(query);
            string sdkmessageId = collection.Entities[0].Id.ToString();

然后是sdkmessagefilterid

//GetSdkMessageFilterId
            query = new QueryExpression("sdkmessagefilter");
            query.ColumnSet = new ColumnSet(true);//"sdkmessagefilterid"
            query.Criteria.AddCondition("primaryobjecttypecode", ConditionOperator.Equal, entityName);
            query.Criteria.AddCondition("sdkmessageid", ConditionOperator.Equal, sdkmessageId);
            collection = organizationServiceProxy.RetrieveMultiple(query);
            string sdkmessagefilterId = collection.Entities[0].Id.ToString();

到这里准备工作就齐活了，然后就是根据参数来创建step了

Entity entity = new Entity("sdkmessageprocessingstep");
            entity.Attributes.Add("name", "NY_AutoNumber.CRM.Plugins.AutoNumber: Create of " + entityName);
            entity.Attributes.Add("description", "NY_AutoNumber.CRM.Plugins.AutoNumber: Create of " + entityName);
            entity.Attributes.Add("sdkmessagefilterid", new EntityReference("sdkmessagefilter", new Guid(sdkmessagefilterId)));
            entity.Attributes.Add("plugintypeid", new EntityReference("plugintype", new Guid(pluginTypesId)));
            entity.Attributes.Add("eventhandler", new EntityReference("plugintype", new Guid(pluginTypesId)));
            entity.Attributes.Add("componentstate", new OptionSetValue(0));
            entity.Attributes.Add("sdkmessageid", new EntityReference("sdkmessage", new Guid(sdkmessageId)));
            entity.Attributes.Add("asyncautodelete", false);
            entity.Attributes.Add("mode", new OptionSetValue(0));
            entity.Attributes.Add("stage", new OptionSetValue(20));
            entity.Attributes.Add("rank", 1);
            entity.Attributes.Add("supporteddeployment", new OptionSetValue(0));
            organizationServiceProxy.Create(entity);

通过上述方式创建出来的step如下
