退出應用程序（無例外）從C＃

引用64位的DLL當我compiled lzo2.dll 64 bit現在看在C＃程序中使用它：退出應用程序（無例外）從C＃

我使用下面的類測試（類似的代碼可用於32位LZO .DLL）：

[DllImport("lzo2.dll")] 
private static extern string lzo_version_string(); 
static void Main(string[] args) 
{ 
    try 
    { 
     if (Environment.Is64BitProcess) 
     { 
      Console.WriteLine(lzo_version_string());//application exits here, no exceptions caught 
     }     
    } 
    catch (Exception e) 
    { 
     Console.WriteLine(e); 
    } 
    Console.ReadLine(); 
}

在點指示的應用程序崩潰，所以我掏出WinDBG的，這裏是的，輸出：

我當時一看（抱歉冗長）在這一點上仍然無法確定問題的暗示。我相信它對符號的抱怨，即使是堆棧跟蹤看起來像它確實有名稱，因此提供了一些含義。有人可以暗示可能是什麼問題或者指向接下來的方向嗎？

它在CFF Explorer和Dependency Walker中打開確定。

還有不是似乎是lzo2.dll本身的問題，因爲測試應用程序作爲構建過程（lzotest.exe -mlzo COPYING）的一部分提供。

一個64位的DLL引用CRT的32位版本的確似乎錯了，幾乎肯定會阻止它加載 – stijn

這是構建過程中的問題呢？我也嘗試重新安裝x64版本的C++ Redistributable軟件包並重新編譯lzo沒有成功 – wal

構建過程可能沒有問題（除非你完全搞砸了你的VS設置，它沒有辦法生成一個64位dll鏈接到32位crt）。我的猜測是Dependency Walker找不到相應的MSVCR100.dll，因此不知道它是64位的，因此不會顯示'64'數字。您的系統路徑可能有問題（即使運行lzo工具？）。重新安裝redist將永遠不會解決這個問題，如果你有VS正確安裝，你不需要單獨的redist：否則你將無法運行由VS創建的任何exe。 – stijn

沒有堆棧跟蹤，但我可以猜測，你可以在那裏看到CoTaskMemFree（）。這是pinvoke編組器調用釋放函數返回的字符串緩衝區的內容。問題是，字符串緩衝區未被CoTaskMemAlloc（）分配。 Vista和Windows 7有更嚴格的內存管理器，它們不允許程序釋放它沒有分配的內存。它在XP上工作，它只是忽略不良的緩衝區指針。

返回字符串的C函數是一個內存管理問題。然而，它可能在這種特定情況下工作，它可能會返回一個不需要釋放的字符串文字。你必須從試圖釋放字符串停止編組，聲明函數是這樣的：

[DllImport("lzo2.dll")] 
private static extern IntPtr lzo_version_string();

，並使用它像這樣：

IntPtr strPtr = lzo_version_string(); 
string version = Marshal.PtrToStringAnsi(strPtr);

中刪除圖像，謝謝，修復它，並感謝詳細的解釋。只是爲了澄清一下，當你說'沒有堆棧跟蹤'時，似乎有一堆有意義名稱的windbg堆棧。缺少什麼讓你說沒有堆棧？（是'CoTaskMemFree'在堆棧跟蹤上） – wal

沒關係，我忘了滾動。 –
