问题 In my custom sorting algorithm, I need to compare numeric types stored as Objects in an array. We can have SByte, Double, Int32, etc values mixed in one array. How can I compare two values of that array in my IComparer implementation? An example. Let's say we have two numeric values: object var1 = (sbyte)-8; object var2 = (double)123.456; It would be nice if code like the following one worked, but it fails: IComparable cmp1 = var1 as IComparable; IComparable cmp2 = var2 as IComparable;

问题 In a legacy ASP.NET Webforms app, I need to update a database table when the user clicks a button, depending on which checkboxes on the form are checked, using the value from a corresponding label to make the update. It's not working; however, almost-identical code in a Winforms "test" app does work.
