【问题描述】：
这是我遇到问题的方法：
[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();
}
我正在尝试上传一个 xml 文件，然后解析成一个 SQL 表（名为 DmgRegister 的 Sql 数据表），我是 ASP.Net 的初学者，如果代码看起来像意大利面条，请见谅。
// SaveXmlToDb method in context
foreach (var item in dmgRegistterList)
{
DmgRegister.Add(item);
}
SaveChanges();
}
现在我正在尝试从 XML 绑定数据并将其保存到 DataTable 的模型

[Serializable()]
[XmlRoot("Claims")]
public class Claims

这是我尝试上传的 Xml 示例

<TotalAmountOfClaimOrigCurr>3680.00</TotalAmountOfClaimOrigCurr>
<Status>Active</Status>
</Claim>
</ns0:Claims>
我什至尝试将它从 XML 转换为 JSON，但它会跳起来捕捉
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");
}
【问题讨论】：
-
请包括您遇到的问题。是构建失败还是您获得的结果有问题？ AFAIK dotnet core 还没有太多的 Xml 支持。您可以改用 Json 来回避这个问题。
-
我正在将 xml 文件上传到 wwwroot，但是它假设从该文件读取到列表中的点失败并且程序提前运行到 Catch
-
抛出异常会很有帮助。更新 try 语句 catch 它：try { } catch(Exception e){ }。 e中的错误是什么？
-
“缺少根元素”
-
当我改变时--- XDocument xDoc = XDocument.Load(fileStream);---- to----- XDocument xDoc = XDocument.Load(filePath);--- 然后我收到此错误消息 该进程无法访问文件“C:\Users\Housam\Desktop\LIA\CapinPhase1\CapinSolutions\CapinSolutions\wwwroot\Solvency2_Insurance_Schema_examples_If_20160208.xml”，因为它正被另一个进程使用。
