C # How to manipulate the config file

The following is the definition of app. Config or Web. config, defines a parameter, the key is Isinit, and the value is False
<?xml version= "1.0"?>
<configuration>
<appSettings>
<add key = "Isinit" value= "false"/>
</appSettings>
</configuration>

Here is the method definition for reading and writing the config file:

Write:

internal void Settingapp_write (string key, String val)  {      System.Configuration.Configuration config = Configurationmanager.openexeconfiguration (configurationuserlevel.none);  Config. appsettings.settings["Isinit"]. Value = val;  Config. Save (configurationsavemode.modified);  Configurationmanager.refreshsection ("appSettings");  }

Read:

Internal string Settingapp_read (string key) {     var val = configurationmanager.appsettings[key];     return Val; }

How to use:

Write test:

Settingapp_write ("Isinit", "true");

Remove test:

var setting = Settingapp_read ("Isinit");

This level of modification is the project-level config file modification, which is the operation of the config file in your final program Bin directory.
