Calling a void async. - Event based pattern, or another method?
- by alex
I have a class that basically stores files in amazon s3.
Here is what it looks like (simplified)
public class S3FileStore
{
public void PutFile(string ID, Stream content)
{
//do stuff
}
}
In my client app, I want to be able to call:
var s3 = new() S3FileStore();
s3.PutFile ("myId", File.OpenRead(@"C:\myFile1"));
s3.PutFile ("myId", File.OpenRead(@"C:\myFile2"));
s3.PutFile ("myId", File.OpenRead(@"C:\myFile3"));
I want this to be an asynchronous operation - I want the S3FileStore to handle this (i don't want my caller to have to execute PutFile asynchronously so to speak) but, i want to be able to trap exceptions / tell if the operation completed for each file.
I've looked at event based async calls, especially this:

However, I can't see how to call my PutFile (void) method?
Are there any better examples?
