这是我的JSON字符串，我只想＆＃34; Name＆＃34;带逗号的字段分隔成另一个变量。

例如，例如：

string res={"JAVA","SPRING","SQL"}

您尝试使用哪种语言？我的第一个猜测是javascript，但我不确定。

如果它是JavaScript，那么你可以通过将json字符串转换为这样的JavaScript对象来开始：

var jsonElements = JSON.parse (json);

从那里它只是循环并从每个对象收集name属性。

现在我们将从C＃改为

好的，既然您正在使用C＃进行解析，那么您需要使用此代码：

string json = "[{\"ParentId\":\"a9764da3147845c184bd272cef6a5937\",\"Path\":\"/LMS/Cabinet/bdc2cd8e1da3451c84e332d1aa74f605\",\"CreatedBY\":\"admin\",\"IsActive\":\"Y\",\"CabinetName\":\"LMS\",\"FolderTag\":\"IT mobile computing,Comm Skills\",\"Name\":\"JAVA\",\"UpdatedBY\":\"\",\"Type\":\"Folder\",\"IsDelete\":\"N\",\"UpdatedON\":\"\",\"Id\":\"bdc2cd8e1da3451c84e332d1aa74f605\",\"CreatedON\":\"2015_09_08-11:19:50\",\"TemplateId\":\"dd42c8a71a954c1d948ef35492ee1242\" },{\"ParentId\":\"a9764da3147845c184bd272cef6a5937\",\"Path\":\"/LMS/Cabinet/3aae020c256f4dc1ab705af67bede2c7\",\"CreatedBY\":\"admin\",\"IsActive\":\"Y\",\"CabinetName\":\"LMS\",\"FolderTag\":\"IT mobile computing,Comm Skills\",\"Name\":\"Spring\",\"UpdatedBY\":\"\",\"Type\":\"Folder\",\"IsDelete\":\"N\",\"UpdatedON\":\"\",\"Id\":\"3aae020c256f4dc1ab705af67bede2c7\",\"CreatedON\":\"2015_09_04-16:58:05\",\"TemplateId\":\"dd42c8a71a954c1d948ef35492ee1242\"},{\"ParentId\":\"a9764da3147845c184bd272cef6a5937\",\"Path\":\"/LMS/Cabinet/c139b33a22a94a25bf624b94450aee3e\",\"CreatedBY\":\"admin\",\"IsActive\":\"Y\",\"CabinetName\":\"LMS\",\"FolderTag\":\"Social Skills\",\"Name\":\"SQL\",\"UpdatedBY\":\"\",\"Type\":\"Folder\",\"IsDelete\":\"N\",\"UpdatedON\":\"\",\"Id\":\"c139b33a22a94a25bf624b94450aee3e\",\"CreatedON\":\"2015_09_04-16:54:44\",\"TemplateId\":\"dd42c8a71a954c1d948ef35492ee1242\"}]";
dynamic jsonObj = (JArray)JsonConvert.DeserializeObject(json);
List<string> names = new List<string>();

foreach (JObject item in jsonObj)
{
     names.Add(item["Name"].ToString());
}

反序列化字符串并将其强制转换为JArray。然后在数组中的foreach元素中，我们查看元素的Name属性。我在visual studio中测试了这段代码，看起来很有用。

想要使用for循环使用逗号分隔来绑定字符串
