The Console.SetError(TextWriter) Method sets the Error property of the specified StreamWriter i.e., it redirects the standard error stream to a file. As the console is set with this StreamWriter object, the WriteLine() method can be called to write the error into the file.
Syntax: public static void SetError (System.IO.StreamWriter newError);
newError: It is a stream which is the new standard error output.
Exception: This method will throw the ArgumentNullException if the parameter passed is null. Also, since it uses the StreamWriter object, it’s exceptions should also be taken care of.
Example: In this example, the SetError() method is used to set the StreamWriter object to the console, and the error messages will be written into a log file from the Console.
Output: The gfg_error.log file will now have the error messages in it.
