C# File is in Use By Another Program

System.IO.File.CreateText(@"C:\\ProgramData\\Password Manager\\pwd.dat");

This makes the file perfectly.

System.IO.File.WriteAllLines(@"C:\\ProgramData\\Password Manager\\pwd.dat", pwd);

But this line gets an error

"The process cannot access the file 'C:\ProgramData\Password Manager\pwd.dat' because it is being used by another process."

Is there a way to close the file before writing to it?

File.CreateText not only create the file, but open it and returns a stream to write the file.
Your subsequent call finds the file blocked by yourself

Try

StreamWriter sw = File.CreateText(@"C:\\ProgramData\\Password Manager\\pwd.dat");
sw.Close();
sw.Dispose();

or simply

using(File.CreateText(@"C:\\ProgramData\\Password Manager\\pwd.dat"))  {}

(The using statement takes care to close and dispose the file)

however, this is completely unnecessary seeing your code because File.WriteAllLines creates the file if it doesn't exist.

You don't need to use CreateText. Simply call WriteAllLines and that will create the file for you. At the moment the stream returned by CreateText is holding onto the file it created which is the reason why the error is thrown.
