我用Microsoft Interop生成一些Excel文件,没问题,我可以创建文件,工作表,文件,密码保护。但我想:
你知道怎么做吗?
谢谢,

花了一段时间,但我想我明白了。我假设你正在使用Excel 2007.我也假设你已经引用了一个范围。这是一个简单的例子。
Excel.Worksheet sheet = this.Application.ActiveSheet as Excel.Worksheet;
Excel.Range range = sheet.get_Range("A1", "A5") as Excel.Range;
//delete previous validation rules
range.Validation.Delete();
range.Validation.Add(Excel.XlDVType.xlValidateWholeNumber,
Excel.XlDVAlertStyle.xlValidAlertStop,
Excel.XlFormatConditionOperator.xlBetween,
0, 1);
这将在 0 和 A5 <之间的特定范围内添加 0 和 1 之间的数字验证/强>
您还可以进一步使用验证对象来创建自定义错误消息等。
希望这有帮助。

如果要验证单元格中的条目,请查看Validation.Add方法。
你的第二个是:
aRange.Validation.Add(XlDVType.xlValidateWholeNumber, XlDVAlertStyle.xlValidAlertStop, XlFormatConditionOperator.xlBetween, 0, 1);

以为我会发布一些可能有用的代码,包括所需的MS命名空间。
using System;
using Excel = Microsoft.Office.Interop.Excel;
using Microsoft.Office.Interop.Excel;
/// <summary>
/// setup this cell to validate (and report error) as decimal value input
/// </summary>
void SetupCellValidation_decimal(Excel.Range cell)
{
try
{
// Delete any previous validation
cell.Validation.Delete();
// Add validation that allows any decimal value
cell.Validation.Add(Excel.XlDVType.xlValidateDecimal, Excel.XlDVAlertStyle.xlValidAlertStop,
Excel.XlFormatConditionOperator.xlBetween, decimal.MinValue, decimal.MaxValue);
cell.Validation.IgnoreBlank = true; // allow blank entries
cell.Validation.ErrorTitle = "Invalid Entry";
cell.Validation.ErrorMessage = "You must enter a valid number";
}
catch (Exception ex)
{
System.Windows.Forms.MessageBox.Show("validate error: " + ex.Message);
}
}
/// <summary>
///
/// </summary>
void exampleCellValidator(Excel.Range cell)
{
try
{
//Delete any previous validation
cell.Validation.Delete();
// for integers:
cell.Validation.Add(Excel.XlDVType.xlValidateWholeNumber, Excel.XlDVAlertStyle.xlValidAlertStop,
Excel.XlFormatConditionOperator.xlBetween, 0, 120);
// for decimal:
cell.Validation.Add(Excel.XlDVType.xlValidateDecimal, Excel.XlDVAlertStyle.xlValidAlertStop,
Excel.XlFormatConditionOperator.xlBetween, decimal.MinValue, decimal.MaxValue);
cell.Validation.IgnoreBlank = true;
// error messaging
cell.Validation.ErrorMessage = "Entry is not a valid number";
cell.Validation.ErrorTitle = "Error - invalid entry";
// use these if you want to display a message each time user activates this cell
cell.Validation.InputTitle = "Entry Rule"; // a message box title
cell.Validation.InputMessage = "You must enter a valid number"; // message to instruct user what to do
}
catch (Exception ex)

System.Windows.Forms.MessageBox.Show("validate error: " + ex.Message);
}
}
