Question

In C#, it seems the following method works which will allow you to
call Streamreader.readline() and then access that very same line in the next loop.

   string line;
    double score = 0;
    count = 0;
    while ((line = sr.ReadLine()) != null)
    {
        score += double.Parse (line);
        count++;
    }
    averageScore = (double)inValue / count;

This does not work in vb.net though, even with all the converters which I tried.

this one completely bombs out and throws “page not found”

this one:

http://www.developerfusion.com/tools/convert/csharp-to-vb/?batchId=3356dd81-818a-43d1-8c23-be584e40d15e
results in :

Dim line As String
Dim score As Double = 0
count = 0
While (InlineAssignHelper(line, sr.ReadLine())) IsNot Nothing
    score += Double.Parse(line)
    count += 1
End While
averageScore = CDbl(inValue) / count

where InlineAssignHelper is something I dont have.

If you have the filename, instead of just a stream, you can use System.IO.File.ReadLines for the neatest way:

Dim score As Double = 0
count = 0

For Each line In File.ReadLines(filename)
    score += Double.Parse(sr.ReadLine())
    count += 1
Next

averageScore = CDbl(inValue) / count

Or use LINQ:

Dim averageScore = File.ReadLines(filename).Average(AddressOf Double.Parse)
