使用Microsoft Interop格式化Excel單元

Question

我使用Microsoft Interop生成一些Excel文件，沒問題，我可以創建文件，工作表，文件，密碼保護。但我想：

• 特定範圍內只允許數字
• 爲其他特定的範圍，只允許數字，但只有0或1

你有一個想法如何做到這一點？

感謝，

Answer 1

了一段時間，但我認爲我得到了它。我假設你正在使用Excel 2007.我也假設你已經有一個範圍的參考。這是一個簡單的例子。

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); 

這將在這種情況下添加數的確認和之間，用於在特定的範圍A1和A5之間。

您也可以與驗證發揮進一步對象來創建自定義錯誤消息等

希望這有助於。

Answer 2

如果您想驗證的進入細胞，看Validation.Add方法。

MSDN Example

你的第二個是一樣的東西：

aRange.Validation.Add(XlDVType.xlValidateWholeNumber, XlDVAlertStyle.xlValidAlertStop, XlFormatConditionOperator.xlBetween, 0, 1);

想到我會發布一些可能有用的代碼，包括需要的MS命名空間。

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); 
    } 
}
