C#, How to delete copy-pase with handlers

C#, How to delete copy-pase with handlers

Please say about "How optimally" rewrite this code without copy-paste. Now
I have two handlers with equivalent lambda handlers... Sorry for more code
and bad style ((
wc.DownloadStringCompleted += (sender, args) =>
{
try
{
res = (T)(object)args.Result;
var cook = Regex.Matches(wc.ResponseHeaders.ToString(),
"Set\\-Cookie:\\s*([\\w\\-_\\.]+\\s*=\\s*[^;]+)",
RegexOptions.IgnoreCase | RegexOptions.Compiled |
RegexOptions.Singleline);
foreach (Match val in cook)
cookies += val.Groups[1].Value.Trim() + "; ";
isComplited = true;
}
catch (Exception e)
{
lastError = e.InnerException.Message;
}
};
wc.UploadDataCompleted += (sender, args) =>
{
try
{
res = (T)(object)args.Result;
var cook = Regex.Matches(wc.ResponseHeaders.ToString(),
"Set\\-Cookie:\\s*([\\w\\-_\\.]+\\s*=\\s*[^;]+)",
RegexOptions.IgnoreCase | RegexOptions.Compiled |
RegexOptions.Singleline);
foreach (Match val in cook)
cookies += val.Groups[1].Value.Trim() + "; ";
isComplited = true;
}
catch (Exception e)
{
lastError = e.InnerException.Message;
}
};
