運行時錯誤被宣佈靜態

我的代碼中插入數據如下它的工作原理是第一次，如果我試圖插入第二次數據我收到錯誤運行時錯誤被宣佈靜態

發生異常的線是什麼？ – 2010-09-24 14:29:02

錯誤發生在哪一行？ – egrunin 2010-09-24 14:29:52

它在代碼中的評論「在這一行我得到錯誤」 – 2010-09-24 14:30:37

我沒有看到它在這個代碼，所以它可能在其他地方發生;但是因爲你從來沒有真正清除過sb，所以你最好還是先在sb = new StringBuilder();之前。

是的，我知道這是一個黑客。

編輯

這是從OP的後續評論明確表示，這個問題是外部顯示的代碼。 @Kirk Woll提出的調試問題的建議是一個好的開始，但考慮到OP的反應，我懷疑某種結構性問題。

是的，這是一個黑客。這是非常溫和的。 – 2010-09-24 14:36:30

問題是，在第二次調用之前Append.sb被設置爲null;因爲它是一個公共成員，所以可以在你的代碼中的任何地方。 – 2010-09-24 14:40:48

因爲很顯然，「SB」是空的，你不知道爲什麼，你可以做最簡單的事情是改變一個屬性，並設置在二傳手斷點等待空賦值：

public static class Append 
{ 
    .... 
    private static StringBuilder _sb = new StringBuilder(); 
    public static StringBuilder sb { 
     get { return _sb; } 
     set { 
      _sb = value; 
     } 
    } 
    .... 
}

放就行了斷點，_sb = value;，看看當/如果它曾經被炒魷魚。當它發生時，看看它是否設置爲空。如果是，請檢查該堆棧以識別違規者。還要在「_sb = new StringBuilder（）;」上放置一個斷點看看什麼時候會被解僱。可以想象的是，在之後，您的方法saveEntry被燒掉了。

即使它顯示相同的錯誤 – Dotnet 2010-09-24 14:47:03

@Dorababu，你是什麼意思？你試過我的建議嗎？它是否停止在任何一個斷點？ – 2010-09-24 15:07:53

在保存條目本身，它正在停止並引發錯誤 – Dotnet 2010-09-24 15:13:48
