Hello
I bind a textbox with a key in app.config file but when change value in the textbox. The changes not shown in the app.config file.
I tried to change value manually by using this line
System.Configuration.ConfigurationSettings.AppSettings.Set("FileSize","50");
It throws an exception that collection is read-only
So what i have to do to change values in the app.config file.
Thanks in advance
Take care
