C # remote connection to the ORACLE database,
To use this method, you only need to input several necessary parameters to test the remote connection of the database. If the connection is successful, TRUE is returned, and false is returned if the connection fails. Note: The first parameter indicates the user in the database, and the second parameter indicates the user's password, the third parameter is not encrypted. It indicates the address of the login server. The fourth parameter indicates the port number of the login server. The fifth parameter indicates the name of the login database. Remember to reference the required parameter. // <summary>
