如何修復Windows窗體設計器中的設計時錯誤？C＃Visual Studio 2008 - Windows窗體設計器中的設計時錯誤

當我MyMainForm.cs點擊[設計]頁，彈出的WinForms我得到以下錯誤：

To prevent possible data loss before loading the designer, the following errors must be resolved: 
    The class name '?' is not a valid identifier for this language.  

    Instances of this error (1)

以下是MainForm.Designer.cs我的錯誤：

讓我知道如果你需要看我的一些代碼，以幫助我

這裏是MainForm.Designer.cs文件代碼：

    protected override void Dispose(bool disposing) 
    { 
     if (disposing && (components != null)) 
     { 
      components.Dispose(); 
     }

嘗試關閉解決方案，重新打開它，然後打開表單。根據我的經驗，這個錯誤可能會消失，只會在以後再次出現。

如果錯誤沒有消失，然後根據
http://connect.microsoft.com/VisualStudio/feedback/details/497218/the-class-name-is-not-a-valid-identifier-for-this-language-can-reproduce-w-vs-2008
和
http://social.msdn.microsoft.com/Forums/en/winformsdesigner/thread/f2c1a027-3e49-4f7f-a4c2-c91a8fde25fc
你可能有太多的右括號的地方。

@JudagSali，謝謝你的迴應。我從MainForm.cs文件中刪除了一個括號，關閉了該文件，並重新打開它，所有的錯誤消失了，設計器加載好了！謝謝！ – 2011-03-22 13:08:52

我有這個錯誤，這是因爲我有一個無效的變量名稱（以數字開始）。希望這可以幫助任何人解決這個問題。

嘗試關閉解決方案，清潔液和重建的解決方案，並將其proble會去，主窗體設計器將可見...

，如果仍然是there..just去n檢查最後修改ü在代碼中完成..在那裏你可能有太多的右括號。

希望這會爲你工作..

通常的做法是在設計代碼中查找錯誤，但我發現這是無益的，因爲在那裏一切都正確（設計器生成的良好代碼，我沒有觸及它）。

該錯誤原來是在我自己的代碼中（一個嘗試失去了花括號）。有趣的是，我的代碼中的錯誤破壞了Designer。我預計它是獨立的（在一定程度上）。
