c# excel在excel工作表上创建一个按钮

Question

我正在尝试在 Excel 工作表上添加一个按钮。
根据来自互联网的示例，我正在尝试执行以下代码。

  using Excel = Microsoft.Office.Interop.Excel;
  using VBIDE = Microsoft.Vbe.Interop;


 private static void excelAddButtonWithVBA()
{
Excel.Application xlApp = new Excel.Application();
Excel.Workbook xlBook = xlApp.Workbooks.Open(@"PATH_TO_EXCEL_FILE");
Excel.Worksheet wrkSheet = xlBook.Worksheets[1];
Excel.Range range;

try
{
    //set range for insert cell
    range = wrkSheet.get_Range("A1:A1");

    //insert the dropdown into the cell
    Excel.Buttons xlButtons = wrkSheet.Buttons();
    Excel.Button xlButton = xlButtons.Add((double)range.Left, (double)range.Top, (double)range.Width, (double)range.Height);

    //set the name of the new button
    xlButton.Name = "btnDoSomething";
    xlButton.Text = "Click me!";
    xlButton.OnAction = "btnDoSomething_Click";

    buttonMacro(xlButton.Name, xlApp, xlBook, wrkSheet);
}
catch (Exception ex)
{
    Debug.WriteLine(ex.Message);
}
xlApp.Visible = true;

}
但它一直说“Excel不包含按钮”
使用 Button 属性时应该包含哪些引用？

Answer 1

据我所知，Excel.Buttons 和 Excel.Button 不存在。相反，建议正确的引用是 Microsoft.Office.Tools.Excel.Controls.Button(不是您使用的 Microsoft.Office.Interop.Excel)。此示例来自以下来源

    Excel.Application xlApp = new Excel.Application();
    Excel.Workbook xlBook = xlApp.Workbooks.Open(@"PATH_TO_EXCEL_FILE");
    Excel.Worksheet worksheet = xlBook.Worksheets[1];

    Excel.Range selection = Globals.ThisAddIn.Application.Selection as Excel.Range;
    if (selection != null)
    {
        Microsoft.Office.Tools.Excel.Controls.Button button =
            new Microsoft.Office.Tools.Excel.Controls.Button();
        worksheet.Controls.AddControl(button, selection, "Button");
    }
