.NET 2.0 : File.AppendAllText(…) - Thread safe implementation

Question

As an exercise in idle curiosity more than anything else, consider the following simple logging class:

internal static class Logging
{
    private static object          


        

Answer 1

It is thread safe in the sense that it opens the file with Read sharing, so assuming your filesystem honors file locks, only one thread will be allowed to write to the file at a time. Other threads may, however, get dirty reads if they are attempting to read the same file.
