如何从Excel中读取date列到C＃中的string？

我正在编写一个C＃控制台应用程序，它使用SmartXLS库从Excel电子表格中读取数据。 我能够读取“使用date”列以外的所有其他列数据。 请告诉我一个解决这个问题的方法。

Excel中的date列：

使用date

Oct-15 Oct-15 Oct-15 

function：

 public void GetData() { int count = 0; DeskTokens = new List<Token>(); string directory = Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location); string path = Path.Combine(directory, @"C:\projects\Product_Usage_Year.xlsx"); SmartXLS.WorkBook WB = new WorkBook(); WB.readXLSX(path); DataTable dt = WB.ExportDataTable(); string CurrentType = string.Empty; string CurrentCategory = string.Empty; DataRow dr; for (int i = 1; i < dt.Rows.Count; i++) { dr = dt.Rows[i]; var tkn = new Token(); tkn.Usagedate = dr[0].ToString(); //error in reading the date column tkn.Product_name = dr[1].ToString(); tkn.Product_Version = dr[2].ToString(); tkn.Userid = dr[3].ToString(); tkn.User_name = dr[4].ToString(); DeskTokens.Add(tkn); count++; Console.WriteLine("Read : " + count); Console.WriteLine(" Reading : " + tkn.Usagedate + "," + tkn.Product_name + "," + tkn.Product_Version + "," + tkn.Userid + "," + tkn.User_name); } } 

令牌类别：

  class Token { public string Usagedate { get; set; } public string Product_name { get; set; } public string Product_Version { get; set; } public string Userid { get; set; } public string User_name { get; set; } }

尝试使用DateTime.FromOADate方法在Excel和.net之间进行转换：

 DateTime.FromOADate(Double.Parse(dr[0].ToString()));
