The specific method of C # operation config file

The following is the definition of app.config or web.config, which 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>

The following is the method definition for the read and write config file:

Write:

Copy Code code as follows:


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:

Copy Code code as follows:


Internal string Settingapp_read (string key)


{


var val = Configurationmanager.appsettings[key];


return Val;


}

How to use:

Write test:

Settingapp_write ("Isinit", "true");

To remove a 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.
