好吧，我承认只有我才会发现这样的小问题

public sealed class ScrollViewer : ContentControl

// // Summary: // Gets a value that represents the horizontal size of the area that can be // scrolled; the difference between the width of the extent and the width of // the viewport.. // // Returns: // The horizontal size of the area that can be scrolled. This property has no // default value. public double ScrollableWidth { get; internal set; }

Silverlight Control里面的小细节，小小小细节... 好几篇这样的文章了，以后学着粗枝大叶一点，产品中的这些小细节太让我恼火了。

补充几句，觉得C#里面的注释写得太像八股文了。最近写了好多好多，现在随便开个东西开始无意识输出的是“Gets or sets a value indicating whether...”。
