Consider: int a = 42; // Reference equality on two boxed ints with the same value Console.WriteLine( (object)a == (object)a ); // False
I turned an Horizontal ItemsControl to a Listbox so that I am able to select individual items but found that the selection was broken. Took some time to distill out the problematic bit.
VB.NET 2010, .NET 4 Hello all, I\'m by no means a good programmer and I\'m just trying to wrap my head around some of this stuff, so please forgive me if this is a dumb question.
This snippet is not compiled in LINQPad. void Main() { (new[]{0,1,2,3}).Where(IsNull).Dump(); } static bool IsNull(object arg) { return arg == null; }
Note: This is a hypothetical discussion. I don\'t actually want to implement a struct String. The .Net String class could be a value type (a struct), because it is immutable and has few members. But
I\'m sure this is fairly trivial but I can\'t get it right. public static string DoSomething(this Enum value)
i have an existing DateTime? object that has a datetime in i开发者_开发技巧t.I want to remove the datetime value from it so when you ask \"HasValue\" it returns false?Nullable<T>is immutable, so
I want to create a simple method that accepts both value type and reference type parameters, i.e. int is value, and string is reference.
I understand that this is an implementation detail. I\'m actually curious what that implementation detail is in Microsoft\'s CLR.
Apologies for the appalling title. I have mocked up this code to mimic an issue I was encountering on a project.
