app.config files..

[Chizl]

I can read .config files all day, but for some reason I cant write to them..
After searching for a few days, there are some that have code showing to
write, but none of them seem to work. Someone explain to me what could be
the problem?

I'm admin of the machine, I'm writting local, and this is the code I've
tried..

Way #1
--------------
Configuration config;
config =
ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
config.AppSettings.Settings[strKey].Value = strValue; //error, Object
reference not set to an instance of an object
config.Save(ConfigurationSaveMode.Modified);
ConfigurationManager.RefreshSection("appSettings");

Way #2

Hi,

we are performing such a tasks with the following:
string sPath = System.IO.Path.Combine(Environment.CurrentDirectory,
"your_exe_name.exe");

Configuration config = ConfigurationManager.OpenExeConfiguration(sPath);

config.AppSettings.Settings["test_key"].Value = "test_value";

config.Save(ConfigurationSaveMode.Modified);

If your <appSettings> section doesn't contain "test_key" you should add it
first (othewise you get null reference exception)

config.AppSettings.Settings.Add("test_key", "test_value");

and than save it.

This should work.
