用c#写入电子表格活动单元格

Question

我编写了一个 C# winforms 程序，它打开一个 excel 电子表格并将整数值 "total" 写入一个单元格（在本例中为 I9）。有什么方法可以让我在电子表格中选择一个单元格，然后在当前活动的单元格中写入我的整数值？

这是与我的问题相关的代码：

    private static Excel.Workbook MyBook = null;
    private static Excel.Application excelApp = null;
    private static Excel.Worksheet MySheet = null;
    private void button4_Click(object sender, EventArgs e)
    {
        OpenFileDialog openb = new OpenFileDialog();
        if (openb.ShowDialog() == DialogResult.OK)
        {
            var name = openb.FileName;
            String filename = DialogResult.ToString();

            excelApp = new Excel.Application();
            excelApp.Visible = true;
            MyBook = excelApp.Workbooks.Open(name);
            MySheet = (Excel.Worksheet)MyBook.Sheets[1]; // Explicit cast is not required here
            MySheet.Cells[9, 9] = total;
            MyBook.Save();
        }
    }

您需要第二个按钮。

第一个打开（并保持打开）您需要的文件，因为您已经拥有它：

private void button4_Click(object sender, EventArgs e)
{
    OpenFileDialog openb = new OpenFileDialog();
    if (openb.ShowDialog() == DialogResult.OK)
    {
        var name = openb.FileName;
        String filename = DialogResult.ToString();

        excelApp = new Excel.Application();
        excelApp.Visible = true;
    }

第二个按钮在用户选择的单元格中写入 total 的值：

    private void button5_Click(object sender, EventArgs e)
    {
        if (excelApp != null && MyBook != null) //sanity check
        {
            MySheet = (Worksheet)MyBook.Sheets[1]; // Explicit cast is not required here
            MySheet.Cells[excelApp.ActiveCell.Row, excelApp.ActiveCell.Column] = total;
            MyBook.Save();
        }
    }
