Manipulating Configuration Parameters: For example Variables in web.config #.Net Web Applications

Leave a comment

Brought from (our old site): http://salearningschool.com/displayArticle.php?table=Articles&articleID=1324&title=Manipulating%20Configuration%20Parameters:%20For%20example%20Variables%20in%20web.config

To access a variable value, you can use the following type of code

   string statusr = WebConfigurationManager.AppSettings["userLoginStatus"].ToString();

   You will need to use: using System.Web.Configuration; or you can write as follows:
   string statusr = 
   System.Web.Configuration.WebConfigurationManager.AppSettings["userLoginStatus"].ToString();

What about if you want to change the values of the variables in the web.config file. Check the code below:


//Compiled
Configuration myConfig = System.Web.Configuration.WebConfigurationManager.OpenWebConfiguration("~");

//change values for the variables in the AppSettings section
myConfig.AppSettings.Settings["userLoginStatus"].Value = "1";

//change values for the connection strings section
myConfig.ConnectionStrings.ConnectionStrings["myDatabaseName"].ConnectionString = 
   "Data Source=....";

myConfig.Save();

//will return you the new value
string statusr = WebConfigurationManager.AppSettings["userLoginStatus"].ToString();

The above code used:
System.Web.Configuration;
using System.Configuration;
