To specify a different encoding, use a different overload of the WriteAllText method. If the specified file does not exist, it is created. If the specified encoding does not match the existing encoding of the file, the specified coding is ignored. The WriteAllText method opens a file, writes to it, and then closes it. Remarks. Use the File class for typical operations such as copying, moving, renaming, creating, opening, deleting, and appending to a single file at a time. You can also use the File class to get and set file attributes or DateTime information related to the creation, access, and writing of a file.
