Wait for Workbook.RefreshAll() (C#)

Question

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

Workbook.RefreshAll();

How can I wait for the <

Answer 1

If you go through your Workbook and set the the BackgroundQuery property of all of your QueryTables to false, RefreshAll should finish before moving on.

foreach (Worksheet worksheet in workbook.Worksheets)
{
    foreach (QueryTable table in worksheet.QueryTables)
        table.BackgroundQuery = false;
}

//This will finish executing before moving on
workbook.RefreshAll();
