oledbdatareader中的行列不存在任何数据

我尝试加载Excel数据列表在这里即时通讯使用oledbdatareader加载数据这里是我的代码

[HttpPost] public ActionResult GetExcelData() { List<ExcelData> exData = new List<ExcelData>(); string status; string fileparth; string json; using (var reader = new StreamReader(Request.InputStream)) { json = reader.ReadToEnd(); } JObject jo = (JObject)JsonConvert.DeserializeObject(json); fileparth = jo.Value<string>("uplaodFile"); string conString = string.Empty; string extension = Path.GetExtension(fileparth); switch (extension) { case ".xls": //Excel 97-03 conString = String.Format("Provider=Microsoft.Jet.OLEDB.4.0;Data Source={0};Extended Properties='Excel 8.0;HDR=YES'", fileparth); break; case ".xlsx": //Excel 07 or higher conString = String.Format("Provider=Microsoft.ACE.OLEDB.12.0;Data Source={0};Extended Properties='Excel 12.0;HDR=YES'", fileparth); break; } using (OleDbCommand cmd = new OleDbCommand()) { excel_con.Open(); string sheet1 = excel_con.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null).Rows[0]["TABLE_NAME"].ToString(); cmd.CommandText = "SELECT * FROM [" + sheet1 + "]"; cmd.Connection = excel_con; using (OleDbDataReader reader = cmd.ExecuteReader()) { int nFields = reader.FieldCount; ExcelData curLine = new ExcelData(); curLine.Actualkm = Convert.ToDecimal(reader[1]); curLine.TRRequestID = reader[0].ToString(); curLine.Amount = Convert.ToDecimal(reader[2]); exData.Add(curLine); } excel_con.Close(); return Json(new { result = "success", data = exData }); // excel_con.Close(); } } 

我得到curLine.Actualkm = Convert.ToDecimal（阅读器1 ）的错误;

这里是我的getters和setter

  public class ExcelData { private string _TRRequestID; public string TRRequestID { get { return _TRRequestID; } set { _TRRequestID = value; } } private decimal _Actualkm; public decimal Actualkm { get { return _Actualkm; } set { _Actualkm = value; } } private decimal _Amount; public decimal Amount { get { return _Amount; } set { _Amount = value; } } } 

这里是我的excel文件

请帮助我，谢谢

代码正试图读取第11行。

我想你不需要空行，所以使用这个

if（！string.IsNullOrEmpty（reader [1] .ToString（））{}

在你使用的代码。
