使用ClosedXML写入Excel单元格后数据无效

我试图向单元格“10.1”中写入一个值,但在写入单元格后,我得到了值:“43110”

class Program
{
    static void Main( string[] args )
    {
        var workbook = new XLWorkbook();
        var worksheet = workbook.Worksheets.Add( "Sample Sheet" );
        worksheet.Cell( "A1" ).Value = "10,1";
        worksheet.Cell( "A1" ).DataType = XLDataType.Text;

        string testValue = worksheet.Cell( "A1" ).Value.ToString();
        Console.WriteLine( testValue );

        workbook.SaveAs( "testSheet.xlsx" );

        Console.ReadKey();
    }
}

如果要运行此示例中的代码,请在此之前从NuGet安装ClosedXML包
