等待Workbook.RefreshAll（）（C＃）

问题描述

我想循环使用目录（使用C＃）并刷新所有Excel表格。我使用：

I want to loop through a directory (using C#) and Refresh all Excel sheets in there. I use:

Workbook.RefreshAll();

如何等待 Workbook.RefreshAll（）语句完成？


问题是：我打开 FileA ， then Workbook.RefreshAll（） 然后打开 FileB - 刷新 FileA 终止。我找到的唯一解决方案是调用类似于

How can I wait for the Workbook.RefreshAll() statement to finish?

The problem is: I open FileA, then Workbook.RefreshAll() and then open FileB - Refresh for FileA is terminated. The only solution I found is to call something like

System.Threading.Thread.Sleep(20000);

我发现非常unlovely ...

which I found very unlovely...

有人知道更好的等待方式吗？

Does someone know a better way to wait?

感谢您的帮助。我找到以下解决方案：

Thanks for your help. I found the following solution:

foreach (MSExcel.WorkbookConnection cnn in wb.Connections)
{
    if (cnn.Type.ToString() == "xlConnectionTypeODBC")
    {
        cnn.ODBCConnection.BackgroundQuery = false;
    }
    else
    {
        cnn.OLEDBConnection.BackgroundQuery = false;
    }
}
