Question

我得到的就是截图制作应用程序。（设法序列化，感谢上帝!!!）当点击一个按钮时，通过访问处理classe的方法获取屏幕截图。现在棘手的部分是该类有另一种方法用于操作上述结果，以这种方式比调用相应的处理方法时，创建一个窗口（显示）并且位图图像应该进入显示容器中那个窗口。问题是到目前为止，我注意到在WPF中，图像控件的源不能归因于存储图像的变量。如何显示存储在该变量中的图像，而无需先保存，获取uri等。？

你需要从内存流中创建一个图像，许多人已经很好地记录了这一点。以下是两个可以帮助您入门的链接：

感谢链接slugster。我是这样做的：

MemoryStream ms = new MemoryStream();
sBmp = gBmp; //note: gBmp is a variable that stores the captured image and passes it on to the method that uses sBMP as a distribuitor of the variable holding the captured image data
//variable that holds image
sBmp.Save(ms,ImageFormat.Bmp);
//my buffer byte
byte[] buffer = ms.GetBuffer();
//Create new MemoryStream that has the contents of buffer
MemoryStream bufferPasser = new MemoryStream(buffer);
//Creates a window with parents classthatholdsthismethod and null
Edit childEdit = new Edit(this, null);
childEdit.Show();
//I create a new BitmapImage to work with
BitmapImage bitmap = new BitmapImage();
bitmap.BeginInit();
bitmap.StreamSource = bufferPasser;
bitmap.EndInit();
//I set the source of the image control type as the new BitmapImage created earlier.
childEdit.imgImageCanvas.Source = bitmap;
childEdit.Activate();

我基本上将我在这些页面上找到的内容与我发现的关于如何将bmp传递给memstream的一些信息相结合。我让它100％工作：）

有没有办法在存储在内存中的WPF中显示图像？
