String[] lines = File.ReadAllLine("filename");
Array.Sort(lines);
File.WriteAllLines("filename", lines);

50 MB is nothing to a modern computer. In memory sorting will be faster than anything else. As a test I created a 54 MB file consisting of 1,470,588 strings. It took 1.729 seconds to read the file, 17.487 seconds to sort it and 0.690 seconds to write the file back to the disk.
