读取/设置超链接或图片类型栏的值

“超链接或图片”类型栏的值，对应的对象模型为SPFieldUrl和SPFieldUrlValue，可以这样读取：

SPFieldUrl fieldUrl = (SPFieldUrl)item.Fields["URL"];
SPFieldUrlValue value = (SPFieldUrlValue)fieldUrl.GetFieldValue(item["URL"].ToString());
Console.WriteLine(value.Description);
Console.WriteLine(value.Url);

 value.Url = "";
 value.Description = "163";
 fieldUrl.Update();
           

或者更简单的方法：

SPFieldUrlValue value = new SPFieldUrlValue(item["URL"].ToString());
       Console.WriteLine(value.Description);
       Console.WriteLine(value.Url);

 

设置

 using (SPSite site = new SPSite("http://basesmcdev/sitedirectory/tester1"))
            {
                using (SPWeb web = site.OpenWeb())
                {
                    SPList list = web.Lists["mosstestchoices"];

                    SPListItem item = list.GetItemById(3);
                   
                    SPFieldUrlValue spfv = new SPFieldUrlValue(item["myhyperlink"].ToString());
                    spfv.Url = "";
                    spfv.Description = "new description";
                    item["myhyperlink"] = spfv.ToString();
                    item.Update();

                }

            }
