Question

hi,
Please answer me.

System.Windows.Markup.XamlParseException when starting WPF Application?

Answer 1

Try this.

string connStr = ConfigurationManager.AppSettings[Constants.appSettingsDataFolderPath].ToString();

Or, you can try this if you have your database connection information in web.config connectionStrings section.

string connStr = ConfigurationManager.ConnectionStrings[Constants.appSettingsDataFolderPath].ConnectionString;

Answer 2

Try:

string connectionString = (string)Application[Constants.appSettingsDataFolderPath];
