Dynamics 365 视图界面，通过分隔符实现批量查询数据（已知编号数组，直接复制到视图可以直接搜索）

效果：

 

 

源码实现：

public class test_RetrieveMultiple_pre : IPlugin {
        public void Execute(IServiceProvider serviceProvider) {
            //上下文
            IPluginExecutionContext context = (IPluginExecutionContext)serviceProvider.GetService(typeof(IPluginExecutionContext));
            //服务工厂
            IOrganizationServiceFactory serviceFactory = (IOrganizationServiceFactory)serviceProvider.GetService(typeof(IOrganizationServiceFactory));
            //组织服务
            IOrganizationService service = serviceFactory.CreateOrganizationService(context.UserId);
            //管理员组织服务
            IOrganizationService serviceAdmin = serviceFactory.CreateOrganizationService(null);

            QueryExpression query = null;
            if (context.InputParameters.Contains("Query") && context.InputParameters["Query"] is QueryExpression) {
                query = (QueryExpression)context.InputParameters["Query"];
            }
            else if (context.InputParameters.Contains("Query") && context.InputParameters["Query"] is FetchExpression) {
                FetchExpression fetch = (FetchExpression)context.InputParameters["Query"];
                var conversionRequest = new FetchXmlToQueryExpressionRequest {
                    FetchXml = fetch.Query
                };
                var conversionResponse = (FetchXmlToQueryExpressionResponse)serviceAdmin.Execute(conversionRequest);

                query = conversionResponse.Query;
            }
            if (query == null) return;

            foreach (var item in query.Criteria.Conditions) {
                if (item.AttributeName.Contains("name")) {
                    //判断原有条件的符号是否是等于
                    if (item.Operator != ConditionOperator.Equal) return;
                    //拆分,根据空格拆分
                    string[] valueStr = item.Values.First().ToString().Split(' ');
                    //组装新条件
                    query.Criteria.AddCondition(item.AttributeName, ConditionOperator.In, valueStr);
                    //将原有条件移除
                    query.Criteria.Conditions.Remove(item);
                    break;
                }

            }
            context.InputParameters["Query"] = query;
        }
    }
