I have a json like this one that comes from an api. I´m using oauth2 so i got the token, then I request the data. I want to count the name inside resources, to know how many are.
{
"startDate": "2019-06-23T16:07:21.205Z",
"endDate": "2019-07-24T16:07:21.205Z",
"status": "Complete",
"usages": [
{
"name": "PureCloud Edge Virtual Usage",
"resources": [
{
"name": "Edge01-VM-GNS-DemoSite01 (1f279086-a6be-4a21-ab7a-2bb1ae703fa0)",
"date": "2019-07-24T09:00:28.034Z"
},
{
"name": "329ad5ae-e3a3-4371-9684-13dcb6542e11",
"date": "2019-07-24T09:00:28.034Z"
},
{
"name": "e5796741-bd63-4b8e-9837-4afb95bb0c09",
"date": "2019-07-24T09:00:28.034Z"
}
]
},
{
"name": "PureCloud for SmartVideo Add-On Concurrent",
"resources": [
{
"name": "[email protected]",
"date": "2019-06-25T04:54:17.662Z"
},
{
"name": "[email protected]",
"date": "2019-06-25T04:54:17.662Z"
},
{
"name": "[email protected]",
"date": "2019-07-15T15:06:09.203Z"
}
]
},
{
"name": "PureCloud 3 Concurrent User Usage",
"resources": [
{
"name": "[email protected]",
"date": "2019-06-25T04:54:17.662Z"
},
{
"name": "[email protected]",
"date": "2019-06-25T04:54:17.662Z"
},
{
"name": "[email protected]",
"date": "2019-07-15T15:06:09.203Z"
}
]
},
{
"name": "PureCloud Skype for Business WebSDK",
"resources": [
{
"name": "[email protected]",
"date": "2019-06-25T04:54:17.662Z"
},
{
"name": "[email protected]",
"date": "2019-06-25T04:54:17.662Z"
},
{
"name": "[email protected]",
"date": "2019-07-15T15:06:09.203Z"
}
]
}
],
"selfUri": "/api/v2/billing/reports/billableusage"
}
This are the classes that i use.
public class Resources
{
public string name { get; set; }
public DateTime date { get; set; }
}
public class Usages
{
public string name { get; set; }
public IList<Resources> resources { get; set; }
}
public class Example
{
public DateTime startDate { get; set; }
public DateTime endDate { get; set; }
public string status { get; set; }
public IList<Usages> usages { get; set; }
public string selfUri { get; set; }
}
This is the function that I use, it receives the url and the token and it gets the data:
static async Task<int> GetNamesCount(string theUrl, string theToken)
{
using (var client = new HttpClient())
{
Records records = new Records();
client.BaseAddress = new Uri(theUrl);
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", theToken);
try
{
HttpResponseMessage response = await client.GetAsync(theUrl);
response.EnsureSuccessStatusCode();
string responseBody = await response.Content.ReadAsStringAsync();
records = (Records)new DataContractJsonSerializer(typeof(Records)).ReadObject(response.Content.ReadAsStreamAsync().Result);
I´ve tried, but I can only count the first two levels. I´ve searched but I can´t use [1] or records.usages["resources"]. What can I do? Thanks in advance.
You could use SelectMany to fetch all resources name inside usages list, and use Count method to calculate the count of names insides resources :
int countNames = records.usages.SelectMany(x => x.resources.Select(y => y.name)).Count();
Or
Use Sum with count
, like :
int countNames = records.usages.Sum(x => x.resources.Count(y => y.name != null));
If you want just the count
of names inside Usages
, you could use :
int countUsagesNames = records.usages.Count;
// or
int countUsagesNames = records.usages.Count(x => x.name != null);
I hope you find this helpful.
