我正在使用CSV Helper库生成CSV文件,让用户填充并上传到系统中。我的问题是WriteHeader方法只写入类的属性,名称为"PropertyValue"之类的,这不太友好。是否有一种方法可以使生成的文本更加用户友好,但仍能成功映射类到文件数据?
我的代码如下:
public ActionResult UploadPropertyCSV(HttpPostedFileBase file)
{
List<PropertyModel> properties = new List<PropertyModel>();
RIMEDb dbContext = new RIMEDb();
bool success = false;
foreach (string requestFiles in Request.Files)
{
if (file != null && file.ContentLength > 0 && file.FileName.EndsWith(".csv"))
{
using(StreamReader str = new StreamReader(file.InputStream))
{
using(CsvHelper.CsvReader theReader = new CsvHelper.CsvReader(str))
{
while (theReader.Read())
{
RIMUtil.PropertyUploadCSVRowHelper row = new RIMUtil.PropertyUploadCSVRowHelper()
{
UnitNumber = theReader.GetField(0),
StreetNumber = theReader.GetField(1),
StreetName = theReader.GetField(2),
AlternateAddress = theReader.GetField(3),
City = theReader.GetField(4)
};
Property property = new Property();
property.UnitNumber = row.UnitNumber;
property.StreetNumber = row.StreetNumber;
property.StreetName = row.StreetName;
property.AlternateAddress = row.AlternateAddress;
property.City = dbContext.PostalCodes.Where(p => p.PostalCode1 == row.PostalCode).FirstOrDefault().City;
dbContext.Properties.Add(property);
try
{
dbContext.SaveChanges();
success = true;
}
catch(System.Data.Entity.Validation.DbEntityValidationException ex)
{
success = false;
RIMUtil.LogError("Ptoblem validating fields in database. Please check your CSV file for errors.");
}
catch(Exception e)
{
RIMUtil.LogError("Error saving property to database. Please check your CSV file for errors.");
}
}
}
}
}
}
return Json(success);
}
我想知道是否有一些元数据标签或其他东西,可以放在我的PropertyUploadCSVRowHelper类的每个属性上方,以便在文件中生成我所需的文本。
先行致谢。
