图片链接字段栏的提取

 “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);

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 = "http://whatever.com";                     spfv.Description = "new description";                     item["myhyperlink"] = spfv.ToString();                     item.Update();

                }

            }
