This method is used to acquire a standard error stream. This method can be used to reacquire the standard error stream after it has been changed by the SetError method.
public static System.IO.Stream OpenStandardError ();
Returns: This method returns the standard error stream.
Example: The below code first checks for the string to be GeeksForGeeks and if not so then the program calls the SetError method to redirect error information to a file, calls the OpenStandardError method in the process of reacquiring the standard error stream, and indicates that error information was written to a file. The StreamWriter.AutoFlush property is set to true before reacquiring the error stream. This ensures that output will be sent to the console immediately rather than buffered.
