Your code structure is not reflecting your json. Common approach to deserializing json with dynamic property names is to use Dictionary<string, …> (supported both by Json.NET and System.Text.Json). Try the following: public class Bike { public int Value { get; set; } public string Type { get; set; } } public class Person { public … Read more
No, volatile wouldn’t be helpful at all, and certainly not for this reason. It would just give that first read “acquire” semantics instead of effectively relaxed, but either way will compile to similar asm that runs a load instruction. if you get a dirty value from a CPU cache CPU caches are coherent, so anything … Read more
If you are using .NET 2 or above you can use the AlternateView and LinkedResource classes like this: string html = @”<html><body><img src=””cid:YourPictureId””></body></html>”; AlternateView altView = AlternateView.CreateAlternateViewFromString(html, null, MediaTypeNames.Text.Html); LinkedResource yourPictureRes = new LinkedResource(“yourPicture.jpg”, MediaTypeNames.Image.Jpeg); yourPictureRes.ContentId = “YourPictureId”; altView.LinkedResources.Add(yourPictureRes); MailMessage mail = new MailMessage(); mail.AlternateViews.Add(altView); Hopefully you can deduce the VB equivalent.

If the DataGridView is databound, you shouldn’t directly modify the content of the cell. Instead, you should modify the databound object. You can access that object through the DataBoundItem of the DataGridViewRow : MyObject obj = (MyObject)dataGridView.CurrentRow.DataBoundItem; obj.MyProperty = newValue; Note that the bound object should implement INotifyPropertyChanged so that the change is reflected in … Read more
Services run in a different window station than the logged in user, so you can’t have a system tray icon for them. From https://learn.microsoft.com/en-us/dotnet/framework/windows-services/introduction-to-windows-service-applications: Windows Service applications run in a different window station than the interactive station of the logged-on user. A window station is a secure object that contains a Clipboard, a set of … Read more
I don’t really follow this guidance unless I’m in the scenarios you need it: there is an actual ambiguity – mainly this impacts either constructors (this.name = name;) or things like Equals (return this.id == other.id;) you want to pass a reference to the current instance you want to call an extension method on the … Read more
The op is asking about the C# equivalent of Java’s throws clause – not the throw keyword. This is used in method signatures in Java to indicate a checked exception can be thrown. In C#, there is no direct equivalent of a Java checked exception. C# has no equivalent method signature clause. // Java – … Read more
textBox1.Background = Brushes.Blue; textBox1.Foreground = Brushes.Yellow; WPF Foreground and Background is of type System.Windows.Media.Brush. You can set another color like this: using System.Windows.Media; textBox1.Background = Brushes.White; textBox1.Background = new SolidColorBrush(Colors.White); textBox1.Background = new SolidColorBrush(Color.FromArgb(0xFF, 0xFF, 0, 0)); textBox1.Background = System.Windows.SystemColors.MenuHighlightBrush;
