编。注意:为了便于阅读而添加换行符
我正在使用Json.NET来解析它,但是它给了我一个空的
and I'm using Json.NET to parse it, however its giving me a null
这是我的代码:
JObject o = JObject.Parse(json); // <- where json is the string above
string name = (string)o["responseData"];
但它给我这个错误:
Can not convert {null} to String.
推荐答案
你尝试过这样的事吗?
string gsearchresultclass= (string)o["responseData"]["results"][0]["GsearchResultClass"];
string title= (string)o["responseData"]["results"][0]["title"];
string titlenoformat= (string)o["responseData"]["results"][0]["titleNoFormatting"];
string url = (string)o["responseData"]["results"][0]["postUrl"];
string content = (string)o["responseData"]["results"][0]["content"];
string author = (string)o["responseData"]["results"][0]["author"];
string blogurl = (string)o["responseData"]["results"][0]["blogUrl"];
string date = (string)o["responseData"]["results"][0]["publishedDate"];
您到底想要进入名称变量的是什么?
What exactly are you trying to get into the name variable?
