我正在使用WPF通過混合和Visual Studio 2012。每次我嘗試使用某些代碼時，都會收到類似這樣的錯誤。對於我的生活，我無法弄清楚。任何幫助表示讚賞，任何解釋都會很棒。'FormWindowState'在當前上下文中不存在

這裏是一個屏幕截圖：

編輯：要看到圖像更清晰，右鍵單擊它並選擇「在新標籤中打開」（如果可用）。

謝謝，我更新了我的代碼。現在它給了我一個新的錯誤。

您可能需要粘貼整個類，所以我們可以看到它的名字。 – 2015-03-18 22:07:48

這不是一個WinForms的東西嗎？你使用WinForms或WPF？ – 2015-03-18 22:08:46

這是一個Winforms類。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

這是WPF。不是Windows窗體。因此，使用像

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

FormWindowState是Windows枚舉窗體應用程序

你可能會從Windows遷移將窗體開發WPF，這就是爲什麼你困惑

下一個錯誤是在這線

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

在這裏

Click="WindowMaximizeButton"

在這裏，您必須在類中指定一個方法名稱，當您單擊該按鈕時將觸發該方法名稱。

但是你給按鈕的本身

您需要設置它像

Click="WindowMaximizeButton_Click"

非常感謝！這工作完美。抱歉，這個平庸的問題。感謝所有的SO貢獻。 – Jake 2015-03-18 22:49:12

但你沒有接受答案。至少請註冊 – Sayka 2015-03-18 22:50:03
