I got you and the code you want is :

 public void saveIdentity(string username, string password, bool impersonate)
    {
        Configuration objConfig = WebConfigurationManager.OpenWebConfiguration("~");
        IdentitySection identitySection = (IdentitySection)objConfig.GetSection("system.web/identity");
        if (identitySection != null)
        {
            identitySection.UserName = username;
            identitySection.Password = password;
            identitySection.Impersonate = impersonate;
        }
    objConfig.Save();
}
