Using ThreadPool.QueueUserWorkItem - thread unexpectedly exits
- by alex
I have the following method:
public void PutFile(string ID, Stream content)
{
try
{
ThreadPool.QueueUserWorkItem(o => putFileWorker(ID, content));
}
catch (Exception ex)
{
OnPutFileError(this, new ExceptionEventArgs { Exception = ex });
}
}
The putFileWorker method looks like this:
private void putFileWorker(string ID, Stream content)
{
//Get bucket name:
var bucketName = getBucketName(ID)
.ToLower();
//get file key
var fileKey = getFileKey(ID);
try
{
//if the bucket doesn't exist, create it
if (!Amazon.S3.Util.AmazonS3Util.DoesS3BucketExist(bucketName, s3client))
s3client.PutBucket(new PutBucketRequest { BucketName = bucketName, BucketRegion = S3Region.EU });
PutObjectRequest request = new PutObjectRequest();
request.WithBucketName(bucketName)
.WithKey(fileKey)
.WithInputStream(content);
S3Response response = s3client.PutObject(request);
var xx = response.Headers;
OnPutFileCompleted(this, new ValueEventArgs { Value = ID });
}
catch (Exception e)
{
OnPutFileError(this, new ExceptionEventArgs { Exception = e });
}
}
I've created a little console app to test this.
I wire up event handlers for the OnPutFileError and OnPutFileCompleted events.
If I call my PutFile method, and step into this, it gets to the "//if the bucket doesn't exist, create it" line, then exits. No exception, no errors, nothing.
It doesn't complete (i've set breakpoints on my event handlers too) - it just exits.
If I run the same method without the ThreadPool.QueueUserWorkItem then it runs fine...
Am I missing something?
