Silverlight 4 WriteableBitmap 到位图
这是我的第一个 Silverlight 应用程序，也是我第一次接触 C#。我有一个 C# 类库，可以使用 COM 从 Silverlight 访问它。 C# 库有一个将 Bitmap 作为参数的方法，但是从我看来，Silverlight 只有一个 WritableBitmap。有没有办法在 Silverlight 中将 WritableBitmap 转换为位图？我读过的其他一些答案给出了用于转换的函数，但这些函数都返回一个位图，这在我尝试构建时显然会引发错误。有人可以帮忙吗？
This is my first Silverlight app and my first go at C#. I have a C# class library that I access from Silverlight using COM. The C# library has a method that takes a Bitmap as an argument, however from what I can see Silverlight only has a WritableBitmap. Is there a way to convert a WritableBitmap to a Bitmap in Silverlight? Some other answers I have read give functions for the conversion, but the functions all return a Bitmap, which obviously throws an error when I try and build. Can anyone help?

最后通过将 WritableBitmap 转换为字节数组，传递它，然后在另一侧再次构建位图来使其工作。
Finally got it working by converting the WritableBitmap into a byte array, passing it through and then building the bitmap again on the other side.
我想确保我正确理解您的意思，您正在使用 Silverlight 与使用 COM 的 C# Windows 库进行对话，C# libraru 正在使用 Silverlight 没有任何引用的类，对吗？
如果是这种情况，我会立即考虑使用 WPF 而不是 Silverlight，你能做到吗？ Bitmap 类实际上只是 GDI+ 图像的包装器，这就是您无法真正在 Silverlight 中使用它的原因。
I want to make sure I am understanding you correctly, you are using Silverlight to talk to a C# windows library using COM, the c# libraru is using classes that Silverlight does not have any references to, correct?
If this is the case, I would immediately look into using WPF instead of Silverlight, can you do this? The Bitmap class is really just a wrapper for a GDI+ image, which is why you wont really be able to use it in Silverlight.
