问题 I am wondering why there is no .ToShortDateString in the .NET Portable Class Library. I have 2 projects (Silverlight, and regular .NET Class Library) that use the same code, and the code involves calling .ToShortDateString() on a DateTime object. In order to reuse the same code instead of copying it in 2 places, I created a portable class library so it can be imported by both Silverlight and .NET Class Library. Unfortunately, it doesn't seem like .ToShortDateString() is available when using

问题 Situation: I have a string that represents the name of a DependencyProperty of a TextBox in Silverlight. For example: "TextProperty". I need to get a reference to the actual TextProperty of the TextBox, which is a DependencyProperty. Question: how do I get a reference to a DependencyProperty (in C#) if all I got is the name of the property? Things like DependencyPropertyDescriptor are not available in Silverlight. It seems I have to resort to reflection to get the reference. Any suggestions?
