在将excel数据导入到mvc中的db时出错“外部表格不是预期的格式”

我收到一个错误

外部表格不是预期的格式

同时在mvc中导入excel数据到db中。

来自entity framework的表

namespace MyCRS { using System; using System.Collections.Generic; using System.Linq; using System.Web; public partial class tblStoreRequest { public int TransactionId { get; set; } public string DocumentNo { get; set; } public System.DateTime RequestedDate { get; set; } public int StoreId { get; set; } public int ArticleId { get; set; } public int RequestedQty { get; set; } public string Remarks { get; set; } public string EnteredBy { get; set; } public System.DateTime EnteredOn { get; set; } public string UpdatedBy { get; set; } public Nullable<System.DateTime> UpdatedOn { get; set; } public virtual AspNetUser AspNetUser { get; set; } public virtual AspNetUser AspNetUser1 { get; set; } public virtual tblArticle tblArticle { get; set; } public virtual tblStore tblStore { get; set; } } } 

Request.xlsx

（在文本中的数据格式就像进入List<string> ）

 ## DocumentNo RequestedDate StoreId ArticleId RequestedQty Remarks ## ## REQ-5 02-09-2016 4 4 100 ##
