通過Microsoft.Office.Interop.Excel確定Excel版本/文化

Question

如何在.NET/C＃中實現這一目標？

Answer 1

閱讀您的app.config文件，因爲它會放置在那裏的參考：

<compilation debug="false"> 
    <assemblies> 
     <add assembly="Office, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71E9BCE111E9429C"/> 
    </assemblies> 
</compilation> 

通過「閱讀」，您可能需要打開文件並讀取其中的內容，因爲我不認爲你可以專門讀取組件。

Answer 2

你可以使用此代碼段：（從我的一個項目採取的，所以不能保證工作的開箱）

Microsoft.Office.Interop.Excel.Application tExcel = new Application(); 
CultureInfo cSystemCulture = Thread.CurrentThread.CurrentCulture; 
CultureInfo cExcelCulture = new CultureInfo(tExcel.LanguageSettings.get_LanguageID(
    Microsoft.Office.Core.MsoAppLanguageID.msoLanguageIDUI)); 

try 
{ 
    Thread.CurrentThread.CurrentCulture = cExcelCulture; 
    double tVersion; 
    bool tParseSucceded = double.TryParse(tExcel.Version, out tVersion); 

    // 12 is the first version with .xlsx extension 
    if (tVersion > 11.5) 
     cDefaultExtension = ".xlsx"; 
    else 
     cDefaultExtension = ".xls"; 

} 
catch (Exception aException) 
{ 
    cLogger.Debug("error retrieving excel version.", aException); 
    cLogger.Error("error retrieving excel version."); 
} 
finally 
{ 
    Thread.CurrentThread.CurrentCulture = cSystemCulture; 
}

void Method1() 
    { 
     string strEVersionSubKey = "\\Excel.Application\\CurVer"; //HKEY_CLASSES_ROOT/Excel.Application/Curver 
     string strValue = null; 
     string strVersion = null; 
     RegistryKey rkVersion = null; 

     rkVersion = Registry.ClassesRoot.OpenSubKey(strEVersionSubKey, false); 


     strValue = (string)rkVersion.GetValue(string.Empty); 

     strValue = strValue.Substring(strValue.LastIndexOf(".") + 1); 


     switch (strValue) //Determine Version 
     { 
      case "7": 
       strVersion = "95"; 
       break; 

      case "8": 
       strVersion = "97"; 
       break; 

      case "9": 
       strVersion = "2000"; 
       break; 

      case "10": 
       strVersion = "2002"; 
       break; 

      case "11": 
       strVersion = "2003"; 
       break; 

      case "12": 
       strVersion = "2007"; 
       break; 

      case "14": 
       strVersion = "2010"; 
       break; 

      case "15": 
       strVersion = "2013"; 
       break; 

      case "16": 
       strVersion = "2016"; 
       break; 
     } 

     MessageBox.Show("Excel " + strVersion + " Installed!"); 



    }
