How can I change the app.config file at run time?
I want to change the connection string:
<add name="WiconEstoqueDataContextConnectionString" connectionString="User Id=USER;Password=PASS;Host=HOST;Database=wicon_estoque;Persist Security Info=True" />
Hello, try this:
var config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
var connectionStringsSection = (ConnectionStringsSection)config.GetSection("connectionStrings");
connectionStringsSection.ConnectionStrings["WiconEstoqueDataContextConnectionString"].ConnectionString = "sua nova conexão";
config.Save();
ConfigurationManager.RefreshSection("connectionStrings");
I hope this can help you.
