为什么我的 WPF 窗口大小默认很大 [英] Why are my WPF window sizes defaulting to be huge

问题描述

我有一个带有几个表单的 wpf 应用程序.在设计时它们很小，并且它们没有设置为自动大小.然而在运行时它们是巨大的，即使它们中没有内容使它们变大.

I have a wpf application with a few forms. At design time they are small, and they are not set to auto size. However at run time they are giant, even with no content in them to make them big.

为什么会这样?

这是其中一种形式

推荐答案

如果您使用此代码创建 :

If you create a <Window/> with this code:

<Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" />

然后，当您从 Visual Studio 运行它时，它将显示一个与您在问题中放置的窗口大小相同的窗口.所以这不是你明确做的任何事情.

Then when you run that from Visual Studio it will display a window the same size as the one you put in your question. So this isn't anything you explicitly did.

您遇到的是 WPF Window 的默认计算大小.对于不同的结果，请在窗口上指定 SizeToContent 参数，正如 paxdiablo 指出的那样，或者使用 MinHeight、MaxHeight 明确设置窗口的大小>、Height、MinWidth、MaxWidth 和/或 Width 属性.

What you've encountered is the default computed size of a WPF Window. For different results, specify a SizeToContent parameter on the Window, as paxdiablo pointed out, or explicitly set the size of your window with the MinHeight, MaxHeight, Height, MinWidth, MaxWidth, and/or Width properties.
