Question

我正在执行邮件合并之后要关闭文件然后关闭单词应用程序。这是我执行邮件合并的地方

Application myWordApp = new Application();
Word.Document myWordDoc = new Word.Document();
myWordDoc = myWordApp.Documents.Add(ref fileDocTempl, ref oMissing, ref oTrue);
myWordApp.Visible = false;
Word.MailMerge wrdMailMerge = myWordDoc.MailMerge;
List<object> listTable = GetTableName();
const string cmdText = "Select * from [{0}]";
Object oQuery = string.Format(cmdText, listTable[0]);
wrdMailMerge.OpenDataSource(excelSource, oMissing, oMissing, oMissing, oMissing, oMissing, oMissing,oMissing, oMissing, oMissing, oMissing, oMissing, oQuery);
myWordApp.MailMergeAfterRecordMerge += myWordApp_MailMergeAfterRecordMerge;
myWordDoc.MailMerge.Execute(ref oFalse);

这是我关闭文件的地方

object doNotSaveChanges = WdSaveOptions.wdDoNotSaveChanges;
myWordDoc.Close(ref doNotSaveChanges, ref oMissing, ref oMissing);
myWordApp.Quit(ref doNotSaveChanges, ref oMissing, ref oMissing);

但是当我关闭myWordDoc时出现以下错误：

RPC_E_CALL_REJECTED COMexeption

只有当我进行大量邮件合并时才会发生这种情况，如果我尝试使用50，一切正常，如果我尝试使用2000，我会收到报告的错误。

可能的解决方法是将块放在while循环中出现错误的位置，并继续循环直到动作实际完成。

var ready = false;
var liCount = 0;
var pDelayBetweenRetry = 500;
var amountOfRetries = 10;
while(!ready)
{
  try
  {
    myWordDoc.Close(ref doNotSaveChanges, ref oMissing, ref oMissing);
    ready = true;
  }
  catch (System.Runtime.InteropServices.COMException loE)
  {
    liCount++;
    if ((uint)loE.ErrorCode == 0x80010001)                      
    {
      // RPC_E_CALL_REJECTED - sleep half sec then try again
      System.Threading.Thread.Sleep(pDelayBetweenRetry);
    }
  }
  finally
  {
    if(liCount == amountOfRetries)
    {
      ready = true;
      //Write error to file or database so you can follow up it didn't worked out 
      //as planned
    }
  }
}

然后再说;这是一种解决方法，这也意味着代码可能仍然存在于循环中==＆gt;继续抛出异常==＆gt;我添加了一个Finally循环来捕捉这种情况。
