＆＃34; jsonr＆＃34;已从原始格式jsoninput.json附加。
jsoninput.json：
[count:[{first:1,second:1,third:1},{first:2,second:2,third:2}]]
我希望能够保存对＆＃34; jsoninput.json＆＃34;所做的更改。将代码附加到jsonr jsoninput.json Server.MapPath FileStream，使用StreamWriter和jsonr="[count:[{first:1,second:2,third:3},{first:11,second:22,third:33},{first:111,second:222,third:333}]]"
using (FileStream fsAppend = new FileStream(Server.MapPath("~/jsoninput.json"), FileMode.Append, FileAccess.Write))
{
StreamWriter sw = new StreamWriter(fsAppend);
sw.Write(jsonr);
sw.Flush();
sw.Close();
StreamWriter Stream = File.AppendText(Server.MapPath("~/jsoninput.json"),jsonr);
Stream.Close();
fsAppend.Close();
}
，如下所示：

{
"data": [
{
"name": "Person 1",
"email": "test@test.com",
"address": {
"address1": "my address 1",
"address2": "my address 2"
}
},
{
"name": "Person 2",
"email": "example@example.com",
"address": {
"address1": "my address 1",
"address2": "my address 2"
}
}
]
}
文件竞争如下：
string jsonr="{
count:[
{first:1,
second:2,
third:3
},
{first:11,
second:22,
third:33
},
{first:111,
second:222,
third:333
}
]
}";
目标json数组添加：
C# jsonr代码将JsonString.json添加到string jsonPath = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "JsonString.json");
string jsonString = File.ReadAllText(jsonPath);
var jsonrObject = JObject.Parse(jsonr)["count"];
JObject o = JObject.Parse(jsonString);
string resultJson = o.Property("data").AddAfterSelf(new JProperty("count", jsonrObject)).ToString();
