这里就是我有问题的方法：从XML文件读入现有的dataTable C＃ASP.NET核心
[HttpPost]
public async Task<IActionResult> XmlPage(IFormFile xmlFile)
{
var uploads = hostingEnvironment.WebRootPath;
if (xmlFile.ContentType.Equals("application/xml") || xmlFile.ContentType.Equals("text/xml"))
{
try
{
using (var fileStream = new FileStream(Path.Combine(uploads, xmlFile.FileName), FileMode.Create))
{
await xmlFile.CopyToAsync(fileStream);
XDocument xDoc = XDocument.Load(fileStream);
List<DmgRegister> dmgRegistterList = xDoc.Descendants("Claim").Select(dmgReg =>
new DmgRegister
{
Uwyear = dmgReg.Element("UWYear").Value,
ClaimNo = dmgReg.Element("ClaimNo").Value,
PolicyNo = dmgReg.Element("PolicyNo").Value,
PolicyName = dmgReg.Element("PolicyHolder").Value,
Address1 = dmgReg.Element("Address1").Value,
Address2 = dmgReg.Element("Addresstype").Value,
PostalLocation = dmgReg.Element("City").Value,
Country = dmgReg.Element("Country").Value,
PostalCode = dmgReg.Element("Postalzone").Value
}).ToList();
context.SaveXmlToDb(dmgRegistterList);
}
catch
{
//Here where i come when i try to upload and parse the data
ViewBag.Error = "Converting fail";
return View("Export");
}
}
else
{
ViewBag.Error = "Uploading fail";
return View("Index");
}
return View();
}
我试着上传一个XML文件，然后解析到一个SQL表（SQL数据表命名DmgRegister），我是一个ASP.Net的初学者，如果代码看起来像意大利式细面条，那么我就会滥用我。
// SaveXmlToDb method in context
foreach (var item in dmgRegistterList)
{
DmgRegister.Add(item);
}
SaveChanges();
}
现在，我想从XML绑定的数据并将其保存到数据表

这里的模型是XML例子，即时通讯试图上传

</ns0:Claims>
我尝试它甚至可以将XML从XML转换为JSON，但它可以跳跃式捕捉到
public async Task<IActionResult> XmlPage(IFormFile xmlFile)
{
var uploads = hostingEnvironment.WebRootPath;
var filePath = Path.Combine(uploads, xmlFile.FileName);
if (xmlFile.ContentType.Equals("application/xml") || xmlFile.ContentType.Equals("text/xml"))
{
try
{
using (var xReader = XmlReader.Create(new StringReader(filePath)))
{
// This line skips the XML declaration, eg "<?xml version=\"1.0\" encoding=\"UTF-8\"?>" - you can skip this if you don't have declaration as in your case
xReader.MoveToContent();
// Gets the actual XMLElement, if any
xReader.Read();
// Convert the xReader to an XNode for the Json serializer
XNode node = XNode.ReadFrom(xReader);
// Json output
string jsonText = JsonConvert.SerializeXNode(node);
}
}
catch
{
ViewBag.Error = "Converting fail";
return View("Export");
}
}
else
{
ViewBag.Error = "Uploading fail";
return View();
}
return View("Index");
}
请注明你是它未能建立experiencing.Is或者是与你所得到的结果的问题的问题？ AFAIK dotnet核心还没有太多的Xml支持。您可以通过使用Json来避开这个问题。 – CountZero
我得到的是在wwwroot上传的xml文件，但是它假设从这个文件读入列表失败，并且程序运行到Catch –
这将有助于抛出异常。更新try语句捕获它：尝试{} catch（Exception e）{}。 e中的错误是什么？ – CountZero
