No, there is no such thing. The closest you can get is this:

foreach( string line = File.ReadLines(fileName) )
{
    foreach( string value in line.Split(new[] { ' ' }, StringSplitOptions.RemoveEmptyEntries);
    {
        someInt = Convert.ToInt32(value);
    }
}

Which could be very memory-intensive if the file contains very long lines.

There may be third party libraries that are better at this, but I wouldn't know any off-hand.
