使用C＃Excel11進行範圍驗證

Question

我一直在網上查找4個小時，我無法做到。

我的目標：創建一個組合，在那裏我可以對物品進行分類，當我點擊其中一個物品時，該物品將單獨出現。

在Excel中，很容易做到，但我無法在C＃中完成。

我找到了這個答案：Other topic，但我不明白「this.Controls」來自哪裏。

感謝您的幫助

Answer 1

我真的不能幫你的Excel的問題，但this.Controls談到最有可能從Windows窗體應用程序。請參閱MSDN上的this文章。 您可以通過創建一個空的Windows窗體應用程序然後在Form1.cs中輸入this.Controls來嘗試它。

Answer 2

我發現我自己，試圖隨機的東西：

範圍m_範圍= Sheet.get_Range（ 「A1」， 「F9」）; m_range.AutoFilter（1， Missing.Value，XlAutoFilterOperator.xlAnd， Missing.Value，true）;

我真的不知道爲什麼，但結果是完美的，最上面一行作爲標題，並添加所有其他細胞...酷

Answer 3

，如果你想使用爲此目的下面的方法是由我寫的驗證添加驗證，當用戶點擊該小區出現一個小的信息框：

/// <summary> 
/// Adds a small Infobox and a Validation with restriction (only these values will be selectable) to the specified cell. 
/// </summary> 
/// <param name="worksheet">The excel-sheet</param> 
/// <param name="rowNr">1-based row index of the cell that will contain the validation</param> 
/// <param name="columnNr">1-based column index of the cell that will contain the validation</param> 
/// <param name="title">Title of the Infobox</param> 
/// <param name="message">Message in the Infobox</param> 
/// <param name="validationValues">List of available values for selection of the cell. No other value, than this list is allowed to be used.</param> 
/// <exception cref="Exception">Thrown, if an error occurs, or the worksheet was null.</exception> 
public static void AddDataValidation(Worksheet worksheet, int rowNr, int columnNr, string title, string message, List<string> validationValues) 
{ 
    //If the message-string is too long (more than 255 characters, prune it) 
    if (message.Length > 255) 
     message = message.Substring(0, 254); 

    try 
    { 
     //The validation requires a ';'-separated list of values, that goes as the restrictions-parameter. 
     //Fold the list, so you can add it as restriction. (Result is "Value1;Value2;Value3") 
     //If you use another separation-character (e.g in US) change the ; appropriately (e.g. to the ,) 
     string values = string.Join(";", validationValues); 
     //Select the specified cell 
     Range cell = worksheet.Cells[rowNr, columnNr]; 
     //Delete any previous validation 
     cell.Validation.Delete(); 
     //Add the validation, that only allowes selection of provided values. 
     cell.Validation.Add(XlDVType.xlValidateList, XlDVAlertStyle.xlValidAlertStop, XlFormatConditionOperator.xlBetween, values, Type.Missing); 
     cell.Validation.IgnoreBlank = true; 
     //Optional put a message there 
     cell.Validation.InputTitle = title; 
     cell.Validation.InputMessage = message; 

    } 
    catch (Exception exception) 
    { 
     //This part should not be reached, but is used for stability-reasons 
     throw new Exception(String.Format("Error when adding a Validation with restriction to the specified cell Row:{0}, Column:{1}, Message: {2}", rowNr, columnNr, message), exception); 

    } 
} 

如果您不需要的信息框，只留下了部分變量標題或消息出現在哪裏。
