我一直在网上搜索,但找不到将单元格变成组合框(或有时似乎被称为下拉菜单)的方法?我正在使用 Microsoft.Office.Interop.Excel 14.0 版(运行时版本 2.0.50727)。

这是我试图实现的解决方案:

Excel.Application App = null;
Excel.Workbook Book = null;

Excel.Worksheet Sheet = null;

object Missing = System.Reflection.Missing.Value;

try
{
    App = new Excel.Application();
    Book = App.Workbooks.Add();

    Sheet = (Excel.Worksheet) Book.Worksheets[1];

    Excel.Range Range = Sheet.get_Range("B2", "B2");

    Range.Validation.Add(Excel.XlDVType.xlValidateList
        , Excel.XlDVAlertStyle.xlValidAlertStop
        , Excel.XlFormatConditionOperator.xlBetween
        , "Item1,Item2,Item3"
        , Type.Missing);
    Range.Validation.InCellDropdown = true;
    Range.Interior.Color = System.Drawing.ColorTranslator.ToOle(System.Drawing.Color.FromArgb(255, 217, 217, 0)); 

    App.Visible = true;
}
finally
{
    Base.ReleaseObject(Sheet);
    Base.ReleaseObject(Book);
    Base.ReleaseObject(App);
}

好吧,肯定存在一个 Excel 可托管的 .Net 组合框。帖子中的示例代码有用吗?

http://msdn.microsoft.com/en-us/library/ee259140(v=vs.100).aspx

Private Sub ExcelRangeAddComboBox()

    Dim ComboBox1 As Microsoft.Office.Tools.Excel. _
        Controls.ComboBox = Me.Controls.AddComboBox( _
        Me.Range("A1", "B1"), "ComboBox1")
    ComboBox1.Items.Add("First Item")
    ComboBox1.Items.Add("Second Item")
    ComboBox1.SelectedIndex = 0

End Sub

如果您不熟悉开发加载项,以下内容可能有助于您入门: http: //msdn.microsoft.com/en-us/library/cc442981 (v=vs.100).aspx
