Have this code
FileUploadSample
works perfectly well on 2.0 but is I implement it in 1.0 (version 1.1.7) project throws "'System.IO.IOException' in mscorlib.dll" exception.
Here controller
[HttpPost]
[DisableFormValueModelBinding]
[ValidateAntiForgeryToken]
public async Task<IActionResult> Upload()
{
if (!MultipartRequestHelper.IsMultipartContentType(Request.ContentType))
{
return BadRequest($"Expected a multipart request, but got {Request.ContentType}");
}
// Used to accumulate all the form url encoded key value pairs in the
// request.
var formAccumulator = new KeyValueAccumulator();
string targetFilePath = null;
var boundary = MultipartRequestHelper.GetBoundary(
MediaTypeHeaderValue.Parse(Request.ContentType),
_defaultFormOptions.MultipartBoundaryLengthLimit);
var reader = new MultipartReader(boundary, HttpContext.Request.Body);
var section = await reader.ReadNextSectionAsync(); //<===Exception hereSorry if I forgot to set temp path somewhere but I am far before reading data to my stream or temp file
