remove white space and blank line from lines of comma text file

It should be more like this:

foreach (string line in File.ReadAllLines("C:\\TESTDATA.txt"))
{
    
    string line1;
    line1 = line.Replace("\t", "");
    line1 = line1.Replace("\r", "");
    line1 = line1.Trim();
    line1 = line1.Replace(" ", "");
}

Of course, it goes without saying that you have to actually *do something* (such as write

to a file) with the string "line1" before leaving that foreach code block or it will be

lost (destroyed when it goes out of scope).
