System.Configuration.ConfigurationManager.AppSettings - question

[Thomas Bauer]

Hello,

I have a config file.

<?xml version="1.0" encoding="utf-8"?>
<configuration>
<appSettings>
<add key="Directory" value="C:\_Database\" />
<add key="CloseApplication" value="0" />
<add key="Extension" value="*.txt,*.log" />
</appSettings>
</configuration>


I read it.


string Directory;
bool CloseApplication;


Directory =
System.Configuration.ConfigurationManager.AppSettings["Directory"];
string help =
System.Configuration.ConfigurationManager.AppSettings["CloseApplication"];
Int32 ret = Convert.ToInt32( help );
// #####// CloseApplication = Convert.ToBoolean( help );


if ( ret == 0 )
CloseApplication = false;
else
CloseApplication = true;


A) Why can I not convert to bool? // #####// CloseApplication =
Convert.ToBoolean( help );
B) All values are string in ConfigurationManager?
C) It is possible in the direct way boolean, double, etc?


Regards Thomas

(Another Way to read/write configuration values)

You can make it a Bool right out of the gate by using the example, and you
can call the examples by name anything you want, like ConfigData --
ConfigSettings.

And with in the Configdata.cs

[ConfigurationProperty("closeapplication")]
public bool CloseApplication {

get { return (bool)this["closeapplication"]; }

set{ this["closeapplication"] = value; }

}
