title: UWP get data usage
body: <p>I love programming for UWP and I start new program with C# and UWP. I want to get network usage for each connection in the target system. I read document in MSDN and I write this code for my app:  </p>
  
  <pre><code>public async static Task&lt;List&lt;ConnectionReport&gt;&gt; GetNetworkUsageAsync(string ConnectionName, DateTimeOffset StartTime, DateTimeOffset EndTime, DataUsageGranularity Granularity)
  {
      var granularityTimeSpan = GranularityToTimeSpan(Granularity);
      try
      {
          var connectionProfile = GetConnectionProfile(ConnectionName);
          var networkUsages = await connectionProfile.GetNetworkUsageAsync(StartTime, EndTime, Granularity, new NetworkUsageStates());
          List&lt;ConnectionReport&gt; listNetworkUsage = new List&lt;ConnectionReport&gt;();
          foreach (var networkUsage in networkUsages)
          {
              var connectionReport = new ConnectionReport()
              {
                  Date = StartTime.Date.ToString(dateFormat),
                  Download = ConvertBytesToMB(networkUsage.BytesReceived),
                  Upload = ConvertBytesToMB(networkUsage.BytesSent),
              };                                     
              listNetworkUsage.Add(connectionReport);
              StartTime = StartTime.Add(granularityTimeSpan);
          }
          return listNetworkUsage;
      }
      catch (Exception ex)
      {                
          // do something
      } 
  }         
  
  private static ConnectionProfile GetConnectionProfile(string ConnectionName)
  {
      var connectionProfiles = NetworkInformation.GetConnectionProfiles();
      foreach (var connection in connectionProfiles)
      {
          if (connection.ProfileName == ConnectionName)
              return connection;
      }            
  }
  
  private static double ConvertBytesToMB(double bytes) =&gt; Math.Round(bytes / 1024 / 1024, 3); 
  
  // Returns the amount of time between each period of network usage for a given granularity
  private static TimeSpan GranularityToTimeSpan(DataUsageGranularity granularity)
  {
      switch (granularity)
      {
          case DataUsageGranularity.PerMinute:
              return new TimeSpan(0, 1, 0);
          case DataUsageGranularity.PerHour:
              return new TimeSpan(1, 0, 0);
          case DataUsageGranularity.PerDay:
              return new TimeSpan(1, 0, 0, 0);
          default:
              return new TimeSpan(0);
      }
  }

  <p>But I don't know my code have some problems or windows 10 build 15063 have some problems because I run my app on two different system and I get same value for all WiFi and Ethernet connections. I always get my network usage with this code but not for a special connection, It's give me my Internet usage however I choose 2 different WiFi.<br>
  Is it possible to say me that it is windows problem or my code have some problems?<br>
  Thanks.</p>
