I think it’s likely you’ll need to deserialize the Json then construct the objects from there. Deserializing directly to Cat or Dog won’t be possible as the deserializer won’t know how to construct these objects specifically. Edit: borrowing heavily from Deserializing heterogenous JSON array into covariant List<> using JSON.NET Something like this would work: interface … Read more

You can change the registered TypeConverter for something using TypeDescriptor.AddAttributes; this isn’t quite the same as Convert.ChangeType, but it may suffice: using System; using System.ComponentModel; static class Program { static void Main() { TypeDescriptor.AddAttributes(typeof(Guid), new TypeConverterAttribute( typeof(MyGuidConverter))); Guid guid = Guid.NewGuid(); TypeConverter conv = TypeDescriptor.GetConverter(guid); byte[] data = (byte[])conv.ConvertTo(guid, typeof(byte[])); Guid newGuid = (Guid)conv.ConvertFrom(data); } … Read more
FileStream gives you a little more control over writing files, which can be beneficial in certain cases. It also allows you to keep the file handle open and continuously write data without relinquishing control. Some use cases for a stream: Multiple inputs Real time data from a memory/network stream. System.IO.File contains wrappers around file operations … Read more
.NET has a number of set operations that work on enumerables, so you could take the set intersection to find members in both lists. Use Any() to find out if the resulting sequence has any entries. E.g. if(list1.Intersect(list2).Any())
As far as I know, certificates are not saved by XML Format , you should combine it by yourself. Is this what you want ? static void Main(string[] args) { X509Certificate2 cer = new X509Certificate2(); cer.Import(@”D:\l.cer”); X509Store store = new X509Store(StoreLocation.CurrentUser); store.Certificates.Add(cer); store.Open(OpenFlags.ReadOnly); X509Certificate2Collection cers = store.Certificates.Find(X509FindType.FindBySubjectName, “My Cert’s Subject Name”, false); if (cers.Count>0) { … Read more
It sounds like you want something like: // No need to sort sites first var grouped = sites.OrderBy(x => x.Type) .GroupBy(x => x.Type); Then just serialize grouped. However, I don’t know quite what an IGrouping will look like in JSON… and the type will be present in each case. You may want something like: var … Read more
It’s working for me <ItemGroup> <None Include=”wwwroot\**”> <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory> </None> </ItemGroup>
Is this a more accurate way of comparing DateTime? Not in the slightest. In fact, that is how the > operator is implemented internally. From the .NET Reference source: public static bool operator >(DateTime t1, DateTime t2) { return t1.InternalTicks > t2.InternalTicks; } Someone might have thought they were being clever by skipping the one … Read more
You could use the set comparer provided by HashSet<T>: var myDictionary = new Dictionary<HashSet<T>, TValue>(HashSet<T>.CreateSetComparer());
