Dynamics CRM2016 Web API之删除单个查找字段值

时间:2022-06-21 10:41:40

      之前的博文中有介绍过,Web Api中的一个删除单个属性的Api但没提供查找字段的删除方法,本篇补充上,这里给出的示例代码是C#的(主要看url的拼接),看下url中最后的/$ref,这个标示表明了当前删除的字段是一个查找类型的,区别就在这。

 string weburi = System.Configuration.ConfigurationManager.AppSettings["WebUri"] 
    + entityName +"(" + guid.Replace("{", "").Replace("}", "") + ")/" + propertyName + "/$ref";
            HttpWebRequest req = (HttpWebRequest)HttpWebRequest.Create(weburi);
            req.Credentials = new NetworkCredential(username, pwd, domain);
            req.Method = "DELETE";
            
            req.ContentType = "application/json; charset=utf-8";
            req.Headers.Add("OData-MaxVersion", "4.0");
            req.Headers.Add("OData-Version", "4.0");
            using (HttpWebResponse res = (HttpWebResponse)req.GetResponse())
            {
                
               
            }
