我試圖訪問我向API進行身份驗證時返回的json字符串的特定字段。當我嘗試打印或操縱我收到的字符串時在C中訪問JSON字符串的字段#
System.NullReferenceException:'未將對象引用設置爲對象的實例。'
var response = client.GetAsync(fullUri).Result;
string content = await response.Content.ReadAsStringAsync();
Console.WriteLine("StatusCode : " + (int)response.StatusCode + " " + response.StatusCode.ToString());
var jo = JObject.Parse(content);
var token = jo["Result"]["Token"].ToString(); //error mentioned above received here
Console.WriteLine(token.ToString()); //error mentioned above also recieved here
Console.WriteLine(content); //error mentioned above received here too
字符串「內容」持有JSON看起來像這樣:
{
"Result":{
"TenantId":"1",
"Token":"38255507",
"UserName":"kadmin",
"RoleId":2,
"ScopeId":"2",
"AdminId":16596942,
"MachineId":null,
"MachineGroupName":null,
"CultureInfo":"en-US",
"TimePref":"Browser",
"OffSetInMinutes":420,
"Attributes":null
},
"ResponseCode":0,
"Status":"OK",
"Error":"None"
}
我已經試過許多應用的例子,我已經看到了計算器,但似乎沒有工作
沒聽清楚不過我還是收到了錯誤。 'Console.WriteLine(token);' 說System.NullReferenceException:'對象引用未設置爲對象的實例。' – Teragon
