我正在使用WPF通过混合和Visual Studio 2012。每次我尝试使用某些代码时，都会收到类似这样的错误。对于我的生活，我无法弄清楚。任何帮助表示赞赏，任何解释都会很棒。'FormWindowState'在当前上下文中不存在

这里是一个屏幕截图：

编辑：要看到图像更清晰，右键单击它并选择“在新标签中打开”（如果可用）。

谢谢，我更新了我的代码。现在它给了我一个新的错误。

您可能需要粘贴整个类，所以我们可以看到它的名字。 – 2015-03-18 22:07:48

这不是一个WinForms的东西吗？你使用WinForms或WPF？ – 2015-03-18 22:08:46

这是一个Winforms类。使用WPF WindowState.Normal。 https://msdn.microsoft.com/en-us/library/system.windows.windowstate%28v=vs.110%29.aspx – 2015-03-18 22:09:05

这是WPF。不是Windows窗体。因此，使用像

this.WindowState = System.Windows.WindowState.Normal;

FormWindowState是Windows枚举窗体应用程序

你可能会从Windows迁移将窗体开发WPF，这就是为什么你困惑

下一个错误是在这线

<Button x:Name="WindowMaximizeButton" Content="Button" Width="14.333" HorizontalAlignment="Right" VerticalAlignment="Top" Style="{DynamicResource WindowMaximizeButton}" Click="WindowMaximizeButton" Margin="0,0,48.998,0">

在这里

Click="WindowMaximizeButton"

在这里，您必须在类中指定一个方法名称，当您单击该按钮时将触发该方法名称。

但是你给按钮的本身

您需要设置它像

Click="WindowMaximizeButton_Click"

非常感谢！这工作完美。抱歉，这个平庸的问题。感谢所有的SO贡献。 – Jake 2015-03-18 22:49:12
