C # reads the TXT configuration file and can update the configuration file

First, the configuration is delimited by the = sign, preceded by the expression of the configuration item, followed by the configured value

Function: Can read TXT configuration file and modify TXT configuration file

We can understand the form of key=value, above, can explain some, no nonsense, the code below it.

Private Static string_path_config = Application.startuppath +"\\config.txt";//configuration file        Private voidForm1_Load (Objectsender, EventArgs e) {            //reading configuration Fileslist<string[]> config =Readfromtxt (); if(Config! =NULL)            {                Try                {                    foreach(string[] Strinchconfig) {                        stringtemp = str[0]; Switch(temp.
