"description" : "Named after the Qashqa'i tribe in Persia, these nomadic rugs represent the skillful weaving styles of the tribe. Combining unique details with traditional family motifs the rugs are heavily ornamented. They often feature geometric patterns and highly developed floral designs. The colors often feature red, saffron yellow and navy. A distinguishable mark of Qashqai antique rugs is the use of flat weave.",

我想替换＆＃34;图像的价值＆＃34;财产如下：
"images": [
{
"position": 1,
"thumb": "/archivesE/upload/8597/20_14/1150426/1150426_t.jpeg",
"small": "/archivesE/upload/8597/20_14/1150426/1150426_l_s.jpeg",
"medium": "/archivesE/upload/8597/20_14/1150426/1150426_l_m.jpeg",
"large": "/archivesE/upload/8597/20_14/1150426/1150426_l.jpeg"
},
{
"position": 2,
"thumb": null,
"small": null,
"medium": null,
"large": ""
},
{
"position": 3,
"thumb": null,
"small": null,
"medium": null,
"large": ""
},
{
"position": 4,
"thumb": null,
"small": null,
"medium": null,
"large": ""
},
{
"position": 5,
"thumb": null,
"small": null,
"medium": null,
"large": ""
},
{
"position": 6,
"thumb": null,
"small": null,
"medium": null,
"large": ""
},
{
"position": 7,
"thumb": null,
"small": null,
"medium": null,
"large": ""
},
{
"position": 8,
"thumb": null,
"small": null,
"medium": null,
"large": ""
},
{
"position": 9,
"thumb": null,
"small": null,
"medium": null,
"large": ""
},
{
"position": 10,
"thumb": null,
"small": null,
"medium": null,
"large": ""
}
],
我试过RegEx：
"images"\s*:\s*\[\s*{[\s\S]+}
更新 这是我用JSON.NET尝试过的： 我无法设置＆＃34;图像＆＃34;的属性值。阵列
void Main()
{
var newValue = new[] { new Test(){Position="1"}, new Test(){Position="2"}};
string json = File.ReadAllText("E:\\JSON.txt");
dynamic rss = JObject.Parse(json);
rss["result"]["furnitureItem"]["images"] = newValue;//this line throws error
Console.WriteLine(rss.ToString());
}
public class Test
{
public string Position {get;set;}
}
答案 0 :(得分：3)
试试这个：
JObject rss = JObject.Parse(json);
JObject furnitures = rss.SelectToken("result").SelectToken("furnitureItem");
furnitures ["images"] = newValue;
