Hi,
I'm using PushStreamContent in asp.net web api to stream data to the client, I have derived from ExceptionFilterAttribute to capture all the exceptions and return standard HttpError to client. However,
I found that exception thrown inside PushStreamContent won't be caught by ExceptionFilterAttribute, it will return a "text/html" error message to client.
Below is the sample code:
response.Content = new PushStreamContent(
async (outputStream, httpContent, transportContext) =>
{
try
{
// do something and throw exception here
}
catch (Exception ex)
{
throw;
}
finally
{
outputStream.Close();
}
});
Comments: There are a couple of issues here. One is when you are using async delegates with PushStreamContent, PushStreamContent never awaits on the delegate. So any exceptions thrown inside are never caught and are unhandled.
