Visual Studio的只是把這個警告屏幕看着我：想不通爲什麼變量是未分配或未申報
我知道這意味着什麼，但我無法弄清楚如何解決它。當我查看「InitializeComponent（）」方法時，一切似乎都很好。這是一個由表格和大量文本框組成的自定義控件。該程序仍然可以毫無錯誤地編譯。我在網上找了一遍找到解決方案，但沒有一個例子真的適合我，我試過的「修補程序」並沒有真正解決任何問題。
變量：
private BiologiskFamiliePanel sdBiologiskFamiliePanel;
的InitializeComponent：
...
this.sdBiologiskFamiliePanel = new Smart_Journal.Controls.BiologiskFamiliePanel();
...
this.sdGroupBox.Controls.Add(this.sdBiologiskFamiliePanel); // Where the Error Message put me
...
this.sdBiologiskFamiliePanel.Location = new System.Drawing.Point(6, 338);
this.sdBiologiskFamiliePanel.Name = "sdBiologiskFamiliePanel";
this.sdBiologiskFamiliePanel.Size = new System.Drawing.Size(329, 272);
this.sdBiologiskFamiliePanel.TabIndex = 2;
你能點的東西，我已經錯過了明顯？

任何時候我在使用WinForms和設計器時都會遇到這些無法解釋的錯誤，因此「微軟修復」一直將其清除。關閉並重新打開Visual Studio，或者刪除並重新添加變量。可能會刪除.suo或.csproj.user文件以清除可能卡住的內容。 –
'this.sdGroupBox' null？ –
我現在已經添加了該類的所有代碼。 – OmniOwl
