C# 5 - asynch method callback with Task.ContinueWIth? [migrated]
- by user1142433
I have a method that pulls some HTML via the HttpClient like so:
public static HttpClient web = new HttpClient();
public static async Task<string> GetHTMLDataAsync(string url)
{
string responseBodyAsText = "";
try
{
HttpResponseMessage response = await web.GetAsync(url);
response.EnsureSuccessStatusCode();
responseBodyAsText = await response.Content.ReadAsStringAsync();
}
catch (Exception e)
{
// Error handling
}
return responseBodyAsText;
}
I have another method that looks like so:
private void HtmlReadComplete(string data)
{
// do something with the data
}
I would like to be able to call GetHTMLDataAsync and then have it call HtmlReadComplete on the UI thread when the html has been read. I naively thought this could somehow be done with something that looks like
GetHTMLDataAsync(url).ContinueWith(HtmlReadComplete);
But, I can't get the syntax correct, nor am I even sure that's the appropriate way to handle it.
Thanks in advance!
