How about: public static Predicate<T> Or<T>(params Predicate<T>[] predicates) { return delegate (T item) { foreach (Predicate<T> predicate in predicates) { if (predicate(item)) { return true; } } return false; }; } And for completeness: public static Predicate<T> And<T>(params Predicate<T>[] predicates) { return delegate (T item) { foreach (Predicate<T> predicate in predicates) { if (!predicate(item)) { … Read more
This code basically does that: class Program { static void Main() { var propName = Nameof<SampleClass>.Property(e => e.Name); Console.WriteLine(propName); } } public class Nameof<T> { public static string Property<TProp>(Expression<Func<T, TProp>> expression) { var body = expression.Body as MemberExpression; if(body == null) throw new ArgumentException(“‘expression’ should be a member expression”); return body.Member.Name; } } (Of course … Read more
For update: Set image list color depth in addition to image size (ilist.ColorDepth = ColorDepth.Depth24Bit) WinForms ListView does not have possibility to change icon spacing, however it can be easily done using Win32. You need to send LVM_SETICONSPACING to your ListView (there is a lot of tutorials how to use SendMessage win32 function in .net, … Read more
Start with the first bitmap by putting it into an Image object Bitmap bitmap = (Bitmap)Image.FromFile(file); Save the bitmap to memory as tiff MemoryStream byteStream = new MemoryStream(); bitmap.Save(byteStream, ImageFormat.Tiff); Put Tiff into another Image object Image tiff = Image.FromStream(byteStream) Prepare encoders: var encoderInfo = ImageCodecInfo.GetImageEncoders().First(i => i.MimeType == “image/tiff”); EncoderParameters encoderParams = new EncoderParameters(2); … Read more
Try to set the position to 0 of your stream and do not use your object but the object type. BinaryFormatter b = new BinaryFormatter(); s.Position = 0; return (YourObjectType)b.Deserialize(s);
Check that your AppDbContext is NOT inherited from DbContext but instead it should be inherited from IdentityDbContext<ApplicationUser>
Despite the fact that using GenerateConsoleCtrlEvent() for sending Ctrl+C signal is the right answer, it needs significant clarification to get it to work in different .NET application types. If your .NET application doesn’t use its own console (Windows Forms/WPF/Windows Service/ASP.NET), the basic flow is: Attach the main .NET process to the console of the process … Read more
In .NET 3.5, there is TimeZoneInfo, which provides a lot of functionality in this area; 2.0SP1 has DateTimeOffset, but this is much more limited. Getting UtcNow and adding a fixed offset is part of the job, but isn’t DST-aware. So in 3.5 I think you can do something like: DateTime eastern = TimeZoneInfo.ConvertTimeBySystemTimeZoneId( DateTime.UtcNow, “Eastern … Read more
So… why not use simple inheritance? Like: class MyGenericClass<T> { } class MyGenericClass : MyGenericClass<int> { } This way you can write both ways: var X = new MyGenericClass<string>(); var Y = new MyGenericClass(); // Is now MyGenericClass<int>
