C# WPF 在AllowTransparency="true" 的窗口上显示WebBrowser 不显示

我正在显示一个带有 WebBrowser 控件的窗口。 我希望窗户是无框的，所以我设置了 WindowStyle="None" 这有效，但在窗口周围显示彩色边框。 Allowstransparency="true" 删除此设置，但不再显示 Web 浏览器（按钮）

我已经发现http://www.neowin.net/forum/topic/646970-c%23-wpf-window-with-transparency-makes-windowsformshost-disappear/ http://www.neowin.net/forum/topic/646970-c%23-wpf-window-with-transparency-makes-windowsformshost-disappear/但我无法让它工作（SetWindowsLong 参数错误）

我知道这是一个老问题，但我今天遇到了完全相同的问题，我使用它解决了它

ResizeMode="NoResize"

代替

Allowstransparency="true"

ResizeMode 也确实删除了恼人的边框，并且不会影响 WebBrowser 控件。在这种情况下似乎是解决您的问题的最简单方法:)
