To return the underlying type of the current enumeration type, the code is as follows −Example Live Demousing System; public class Demo { enum Vehicle {Car, Bus, Bike, Airplane} public static void Main() { try { Vehicle v = Vehicle.Bike; Type type = v.GetType(); string[] str = type.GetEnumNames(); Console.WriteLine("GetEnumName() to return the constant name = " + str); Type type2 = type.GetEnumUnderlyingType(); Console.Write("Enum Underlying type = "+type2); Console.WriteLine("Listing ...

To get the names of the members of the current enumeration type, the code is as follows −Example Live Demousing System; public class Demo { enum Vehicle {Car, Bus, Bike} public static void Main() { try { Type type = typeof(string); string[] str = type.GetEnumNames(); Console.WriteLine("GetEnumName() to return the constant name = " + str); Console.WriteLine("Listing constants .."); for (int i = 0; i < str.Length; i++) Console.Write("{0} ", str[i]); ...

To convert the specified Windows file time to an equivalent local time, the code is as follows −Example Live Demousing System; public class Demo { public static void Main() { DateTimeOffset offset = DateTimeOffset.FromFileTime(0); Console.WriteLine("DateTimeOffset = {0:dd} {0:y}, {0:hh}:{0:mm}:{0:ss} ",offset); } }OutputThis will produce the following output −DateTimeOffset = 01 January 1601, 12:00:00ExampleLet us see another example − Live Demousing System; public class Demo { public static void Main() { DateTimeOffset offset = DateTimeOffset.FromFileTime(200000000); Console.WriteLine("DateTimeOffset = {0:dd} {0:y}, {0:hh}:{0:mm}:{0:ss} ",offset); } }OutputThis will produce the following output −DateTimeOffset = 01 January 1601, 12:00:20
To check if a thread belongs to managed thread pool or not, the code is as follows −Example Live Demousing System; using System.Threading; public class Demo { public static void Main() { Thread thread = new Thread(new ThreadStart(demo)); thread.Start(); } public static void demo() { Console.WriteLine("Thread belongs to managed thread pool? = "+Thread.CurrentThread.IsThreadPoolThread); } }OutputThis will produce the following output −Thread belongs to managed thread pool? = FalseExampleLet us see another example −using System; using System.Threading; public class Demo { public static void Main() { ThreadPool.QueueUserWorkItem(new WaitCallback(demo)); } public ...

To check if an array is synchronized or not, the code is as follows −Example Live Demousing System; public class Demo { public static void Main() { string[] products = new string[] { }; Console.WriteLine("One or more planets begin with 'E'? = {0}", Array.Exists(products, ele => ele.StartsWith("E"))); Console.WriteLine("Is the array having fixed size? = " + products.IsFixedSize); Console.WriteLine("Is the array read only? = " + products.IsReadOnly); Console.WriteLine("Is the array synchronized? = " + products.IsSynchronized); } }OutputThis will produce the following output ...
