Determine Excel Version/Culture via Microsoft.Office.Interop.Excel
14,301
You could use this code snippet: (taken from one of my projects, so not guaranteed to work out of the box)
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;
}

How can I achieve that in .NET/C#?

Jay almost 14 yearsInstead of reading the app.config file you could use reflection name space with Assembly myAss = Assembly.GetAssembly(type) where type is a type of object from the Excel assembly. The FullPath property would return the same information as is stored in the app.config and you could just parse that.

DonKotlino almost 14 yearsUsing reflection I could determine the Excel version and culture but I still need to know the Office/Excel installation language. How can I discover that?
