我正在使用LibreOffice執行郵件合併的C＃應用程序。
我可以執行郵件合併並將結果保存爲pdf，但在撥打xDesktop.terminate()後發生崩潰，並且在下次打開LibreOffice時出現崩潰報告。在C＃中執行郵件合併時LibreOffice崩潰
每次我使用com.sun.star.text.MailMerge服務並關閉LibreOffice時，用作郵件合併基礎的模型都不會從臨時文件夾中刪除。
例如文件：
%TEMP%\lu97964g78o.tmp\lu97964g78v.tmp
%TEMP%\lu97964g78o.tmp\SwMM0.odt
看來，我沒有正確關閉郵件合併服務。
最少的代碼來重現作家崩潰：
// Program.cs
using System;
using System.IO;
namespace LibreOffice_MailMerge
{
class Program
{
static void Main(string[] args)
{
// LibreOffice crash after calling xDesktop.terminate().
// The crash reporting appear when the second itaration begins.
int i;
for (i = 0; i < 2; i++)
{
//Minimal code to reproduce the crash.
using (var document = new TextDocument())
{
document.MailMerge();
}
}
}
}
}
// TextDocument.cs
using Microsoft.Win32;
using System;
using unoidl.com.sun.star.frame;
using unoidl.com.sun.star.lang;
using unoidl.com.sun.star.uno;
namespace LibreOffice_MailMerge
{
class TextDocument : IDisposable
{
private XComponentContext localContext;
private XMultiComponentFactory serviceManager;
private XDesktop xDesktop;
public TextDocument()
{
InitializeEnvironment(); // Add LibreOffice in PATH environment variable.
localContext = uno.util.Bootstrap.bootstrap();
serviceManager = localContext.getServiceManager();
xDesktop = (XDesktop)serviceManager.createInstanceWithArgumentsAndContext("com.sun.star.frame.Desktop", new uno.Any[] { }, localContext);
}
public void MailMerge()
{
// #############################################
// # No crash if these two lines are commented #
// #############################################
var oMailMerge = serviceManager.createInstanceWithArgumentsAndContext("com.sun.star.text.MailMerge", new uno.Any[] { }, localContext);
((XComponent)oMailMerge).dispose();
}
public void Dispose()
{
if (xDesktop != null)
{
xDesktop.terminate();
}
}
}
}
操作系統：Windows 10和64位的Windows 7 32位
的LibreOffice和SDK版本：5.3.0.3 86 （還測試了5.2.4.2和5.2.5.1 x86）
LibreOffice快速啓動：禁用
Crashreport
Complete Visual Studio project在GitHub上。
非常感謝任何能告訴我我錯在哪裏的人。
編輯：更新代碼並提交錯誤報告。
編輯2：希望做一些有用的事情，我發佈了一個解決上述問題的解決方法。
基本上，我通過傳遞一個參數來創建一個新的用戶配置文件來啓動LibreOffice進程。
我還將僅用於LibreOffice進程的tmp環境變量的路徑更改爲指向上一個目錄。
當我完成工作時，我刪除了該目錄，其中包含由LibreOffice API錯誤創建的崩潰報告和臨時文件。

它看起來像代碼缺少關閉文檔的命令。例如'xCloseable.close（true）;'如下所示：https：//wiki.openoffice.org/wiki/Documentation/DevGuide/OfficeDev/Closing_Documents。 –
@JimK謝謝，但我已經看到了這個鏈接，我已經在使用xCloseable關閉郵件合併創建的文檔。 我在github上創建了一個存儲庫，並提供了我使用的更完整的代碼示例。 郵件合併的作品，但總是發生我提到的崩潰。 – Simone
