Topic: web api how to use Request.Files
below is the piece of code for referrence developed in .net framework api but, the same code is not working in .net core api projects. especially Request.Files since, in .net core there is no such a propery called Request.Files. From google some people said to include
Microsoft.AspNetCore.App but, then also its not working. Could you please suggest a work around wtih sample code?
[HttpPost]
public HttpResponseMessage UploadFile()
{
foreach (string file in Request.Files)
{
var FileDataContent = Request.Files[file];
if (FileDataContent != null && FileDataContent.ContentLength > 0)
{
// take the input stream, and save it to a temp folder using the original file.part name posted
var stream = FileDataContent.InputStream;
var fileName = Path.GetFileName(FileDataContent.FileName);
var UploadPath = Server.MapPath("~/App_Data/uploads");
Directory.CreateDirectory(UploadPath);
string path = Path.Combine(UploadPath, fileName);
try
{
if (System.IO.File.Exists(path))
System.IO.File.Delete(path);
using (var fileStream = System.IO.File.Create(path))
{
stream.CopyTo(fileStream);
}
// Once the file part is saved, see if we have enough to merge it
Shared.Utils UT = new Shared.Utils();
UT.MergeFile(path);
}
catch (IOException ex)
{
// handle
}
}
}
return new HttpResponseMessage()
{
StatusCode = System.Net.HttpStatusCode.OK,
Content = new StringContent("File uploaded.")
};
}
