Question

我需要一个给定实体的所有表单列表（multiform）;我知道客户端Javascript代码的解决方案，但我使用的是服务器端代码。

我尝试使用此消息来获取实体元数据，但我无法在那里找到它：

    RetrieveEntityRequest mdRequest = new RetrieveEntityRequest()
    {
        EntityFilters = EntityFilters.All,
        LogicalName = entityName,
        RetrieveAsIfPublished = false
    };

我尝试检索实体FormXML，但它不存在：

private string GetFormXML(int objectTypeCode)
{
        QueryExpression q = new QueryExpression("systemform");
        q.ColumnSet = new ColumnSet("formxml");
        q.Criteria.AddCondition(new ConditionExpression("type", ConditionOperator.Equal, 2));
        q.Criteria.AddCondition(new ConditionExpression("objecttypecode", ConditionOperator.Equal, objectTypeCode));

        var entities = ctx.OrganizationService.RetrieveMultiple(q);

        if (entities != null)
        {
            return entities.Entities.First().Attributes["formxml"].ToString();
        }
        else
        {
            return "";
        }
}

有什么建议吗？

Answer 1

我认为systemform实体将objecttypecode作为字符串，它接受实体名称而不是真实实体对象类型代码。您可以尝试将对象类型代码从数字更改为实体名称吗？

private string GetFormXML(int objectTypeCode)
{
        QueryExpression q = new QueryExpression("systemform");
        q.ColumnSet = new ColumnSet("formxml");
        q.Criteria.AddCondition(new ConditionExpression("type", ConditionOperator.Equal, 2));
        q.Criteria.AddCondition(new ConditionExpression("objecttypecode", ConditionOperator.Equal, "contact"));

        var entities = ctx.OrganizationService.RetrieveMultiple(q);

        if (entities != null)
        {
            return entities.Entities.First().Attributes["formxml"].ToString();
        }
        else
        {
            return "";
        }
}

        public Dictionary<Guid, string> GetNevegationItems(int objectTypeCode)
    {
        QueryExpression q = new QueryExpression("systemform");
        q.ColumnSet = new ColumnSet("name", "formid");
        q.Criteria.AddCondition(new ConditionExpression("type", ConditionOperator.Equal, 2));
        q.Criteria.AddCondition(new ConditionExpression("objecttypecode", ConditionOperator.Equal, objectTypeCode));

        var entities = ctx.OrganizationService.RetrieveMultiple(q);

        if (entities != null)
        {
            Dictionary<Guid, string> rslt = new Dictionary<Guid, string>();
            foreach (var item in entities.Entities)
            {
                rslt.Add(item.GetAttributeValue<Guid>("formid"), item.GetAttributeValue<string>("name"));
            }
            return rslt;
        }
        else
        {
            return null;
        }
    }
