C# - Excel：删除行，取决于第一列中的值

Question

想象一下，你有 A 列。 有 100 行，单元格中有数字，例如 1、2、3 直到 100..

如何以编程方式 (C#) 删除特定行，例如：删除行 A 列中的值为 5..

我正在使用 Microsoft.Office.Interop.Excel，这就是相关代码：

        Microsoft.Office.Interop.Excel.Application xlApp = new Microsoft.Office.Interop.Excel.Application();
        Microsoft.Office.Interop.Excel.Workbook xlWorkbook = xlApp.Workbooks.Open(@"C:\Users\fre\Desktop\TestDatei.xls");
        Microsoft.Office.Interop.Excel._Worksheet xlWorksheet = xlWorkbook.Sheets[1];
        Microsoft.Office.Interop.Excel.Range xlRange = xlWorksheet.UsedRange;

        xlWorksheet.Select(Type.Missing);
        Microsoft.Office.Interop.Excel.Range range = xlWorksheet.get_Range("B1:B5", Type.Missing);
        range.Delete(Microsoft.Office.Interop.Excel.XlDeleteShiftDirection.xlShiftUp);

因为我也很感兴趣，所以我在网上做了一些调查并创建了一些示例代码。也许这可以帮助你：

    private void DeleteCells(object sender, EventArgs e)
    {
        // create excel-instance:
        Excel.Application excel = new Excel.Application();
        // open the concrete file:
        Excel.Workbook excelWorkbook = excel.Workbooks.Open(@"D:\test.xls");
        // select worksheet. NOT zero-based!!:
        Excel._Worksheet excelWorkbookWorksheet = excelWorkbook.Sheets[1];
        // create a range:
        Excel.Range usedRange = excelWorkbookWorksheet.UsedRange;

        // iterate range
        foreach (Excel.Range r in usedRange)
        {
            // check condition:
            if (r.Value2 == 5.0F)
                // if match, delete and shift remaining cells up:
                r.Delete(Excel.XlDeleteShiftDirection.xlShiftUp);
        }

        // save changes (!!):
        excelWorkbook.Save();

        // cleanup:
        if (excel != null)
        {
            Process[] pProcess;
            pProcess = System.Diagnostics.Process.GetProcessesByName("Excel");
            pProcess[0].Kill();
        }
    }

你好！

如果你想删除整行，试试这个吧

Range usedRanage=sheet.UsedRange;
foreach (Range r in usedRanage) 
{
    if (Convert.ToString(r.Value2)=="RETRIEVE") 
    {
        r.EntireRow.Delete(XlDeleteShiftDirection.xlShiftUp);
    }
}
