我在整个项目中使用 C# 将 Excel 单元格填充为行和列,如下所示。现在有在特定单元格中添加下拉列表的新要求。
var oXl = new Microsoft.Office.Interop.Excel.Application {DisplayAlerts = false};
var oWb = oXl.Workbooks.Open(excelFileName);
Microsoft.Office.Interop.Excel._Worksheet oSheet = oWb.Sheets[2];
oSheet.Cells[row, 1] = changeName + "\t";
oSheet.Cells[row, 2] = newName + "\t";
oSheet.Cells[row, 3] = (i + 1) + "\t";
oSheet.Cells[row, 4] = filename;
oSheet.Cells[row, 5] = type;
oSheet.Cells[row, 8] = dropdown; // Here I need to add a dropdown list
我该怎么做?
最佳答案
首先为下拉列表制作一个列表
var list = new System.Collections.Generic.List<string>();
list.Add("Charlie");
list.Add("Delta");
list.Add("Echo");
var flatList = string.Join(",", list.ToArray());
然后将此列表添加为特定单元格中的下拉列表,如下所示
var cell = (Microsoft.Office.Interop.Excel.Range)oSheet.Cells[row, 8];
cell.Validation.Delete();
cell.Validation.Add(
XlDVType.xlValidateList,
XlDVAlertStyle.xlValidAlertInformation,
XlFormatConditionOperator.xlBetween,
flatList,
Type.Missing);
cell.Validation.IgnoreBlank = true;
cell.Validation.InCellDropdown = true;
