在 Excel 文件中获取带有公式的单元格

问题描述:

我正在尝试阅读单元格的公式,我正在阅读工作表中的所有单元格,这需要太多时间.我怎样才能只选择那些有公式的单元格.

I am trying to read formulas of cells currently I am reading all cells in sheet which takes too much time. How can I only select those cells which have formulas.

这是我使用的代码

foreach (Excel.Worksheet workSht in xWorkBook.Worksheets)
{
    for (int rCnt = 1; rCnt <= workSht .Rows.Count; rCnt++)
    {
        for (int cCnt = 1; cCnt <= workSht .Columns.Count; cCnt++)
        {
            string str = (string)(workSht.Cells[rCnt, cCnt] as Excel.Range).Formula;
            if (str.Contains("_R*"))
            {
                if (File.Exists(excelFilePath))
                {
                    File.Delete(excelFilePath);
                }
                CloseExcelObject(ref xWorkBook, ref xApp);
                return "UnReviewedFile";
            }
        }
    }
}

在 VBA 中,您可以使用以下语句选择所有包含公式的单元格:

In VBA you can select all the cells containing formulas with the following statement:

Sheet1.Cells.SpecialCells(xlCellTypeFormulas, 23).Select

其中 Sheet1 是对当前工作表的引用,xlCellTypeFormulas = -4123

where Sheet1 is a reference to the current sheet and xlCellTypeFormulas = -4123

这意味着您应该能够使用类似于以下代码(未测试)的公式搜索单元格:

That means you should be able to search through the cells with formulas with something like the following code (not tested):

foreach (Excel.Worksheet workSht in xWorkBook.Worksheets)
{
    foreach (var cell in workSht.Cells.SpecialCells(-4123, 23)) {
        // your code here
    }  
}
