"IndexOutOfRangeException : 인덱스가 배열 경계를 벗어났습니다." SqlDb ASP.NET MVC 6

Question

2 열이있는 CSV 파일을 업로드해야합니다. 1.Key 2.Value 및 변환 테이블의 DB에 저장해야하지만 오류가 발생합니다. "IndexOutOfRangeException : 인덱스 배열의 범위를 벗어난 것입니다." 내 코드는 다음과 같습니다. 여기

[HttpPost("application/UploadCSV/{id}")] 
    public async Task<ActionResult> UploadCSV(UploadCSVModelView uploadFileMV, int Id) 
    {  
     var csvReader = new StreamReader(uploadFileMV.UploadedFile.OpenReadStream()); 

     var values = new List<string>(); 
     var appId = _applicationlanguageService.GetAll().Where(x => x.ApplicationId == Id).Select(x => x.Id).FirstOrDefault(); 
     List<Translation> listTrans = new List<Translation>(); 

     while (!csvReader.EndOfStream) 
     { 
      string abc = csvReader.ReadLine(); 
      var item = abc.Split(','); 
      listTrans.Add(new Translation(){ KeyName= item[0], Value = item[3], State = (int)EnumState.Created, ApplicationLanguageId = appId, CreatedBy = User.Identity.Name, CreatedOn = DateTime.UtcNow}); 

     } 
     if (ModelState.IsValid) 
     { 
      await _translationService.CreateAsync(listTrans); 
     } 


     return RedirectToAction("Index"); 
    } 

내 번역 모델

public class Translation : BaseEntity 
{ 
    [DatabaseGenerated(DatabaseGeneratedOption.Identity)] 
    public int Id { get; set; } 
    public string KeyName { get; set; } 
    public string Value { get; set; } 
    public int State { get; set; } 

    [ForeignKey("ApplicationLanguageId")] 
    public int ApplicationLanguageId { get; set; } 
    public virtual ApplicationLanguage ApplicationLanguage { get; set; } 
}

 while (!csvReader.EndOfStream) 
     { 
      try 
      { 
       string abc = csvReader.ReadLine(); 
       var item = abc.Split(','); 
       if (item != null) 
       { 
        listTrans.Add(new Translation() 
        { 
         KeyName = item[0], 
         Value = item[3], 
         State = (int)EnumState.Created, 
         ApplicationLanguageId = appId, 
         CreatedBy = User.Identity.Name, 
         CreatedOn = DateTime.UtcNow 
        }); 
       } 
      } 
      catch (Exception ex) 
      { 

      } 
     } 

그것은 지금 작동하고, 문제는 내가
