Ended up creating a converter: public class BoolConverter : JsonConverter { public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer) { writer.WriteValue(((bool)value) ? 1 : 0); } public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer) { return reader.Value.ToString() == “1”; } public override bool CanConvert(Type objectType) { return objectType == typeof(bool); } … Read more
Expando is a dynamic type to which members can be added (or removed) at runtime. dynamic is designed to allow .NET to interoperate with types when interfacing with dynamic typing languages such as Python and JavaScript. So, if you need to handle a dynamic type: use dynamic and if you need to handle dynamic data … Read more
Here is code sample that you can use to retrieve time from NIST Internet Time Service var client = new TcpClient(“time.nist.gov”, 13); using (var streamReader = new StreamReader(client.GetStream())) { var response = streamReader.ReadToEnd(); var utcDateTimeString = response.Substring(7, 17); var localDateTime = DateTime.ParseExact(utcDateTimeString, “yy-MM-dd HH:mm:ss”, CultureInfo.InvariantCulture, DateTimeStyles.AssumeUniversal); }
DataTable.Rows returns a DataRowCollection which only implements IEnumerable, not IEnumerable<DataRow>. Use the AsEnumerable() extension method on DataTable (from DataTableExtensions) instead: Parallel.ForEach(dt.AsEnumerable(), drow => { … Do Stuff … });
Try: var handler = new HttpClientHandler() { AllowAutoRedirect = false }; HttpClient client = new HttpClient(handler);
Why don’t you just generate two random Int32 values and make one Int64 out of them? long LongRandom(long min, long max, Random rand) { long result = rand.Next((Int32)(min >> 32), (Int32)(max >> 32)); result = (result << 32); result = result | (long)rand.Next((Int32)min, (Int32)max); return result; } Sorry, I forgot to add boundaries the first … Read more
Shouldn’t be tough to verify: class Program { static void Main() { Task .Factory .StartNew(() => Console.WriteLine(Thread.CurrentThread.IsBackground)) .Wait(); } } And the answer is … ǝnɹʇ
