Question

当我创建角色时，我只能传递一个参数RoleName。如果我传递多个参数，则显示错误。如何传递多个参数来插入表。

[HttpPost]
        [MyExceptionHandler]
        [ValidateAntiForgeryToken]
        public ActionResult RoleCreate([Bind(Include = "RoleName,Status,CreatedBy,CreatedDate,ModifiedBy,ModifiedDate")]Role role)
        {
            if (ModelState.IsValid)
            {
                if (Roles.RoleExists(role.RoleName))
                {
                    ModelState.AddModelError("Error", "Rolename already exists");
                    return View(role);
                }
                else
                {
                    Roles.CreateRole(role.RoleName, role.Status,role.CreatedBy,role.CreatedDate,role.ModifiedBy,role.ModifiedDate);
                    return RedirectToAction("ViewRole", "Account");
                }
            }
            else
            {
                ModelState.AddModelError("Error", "Please enter Username and Password");
            }
            return View(role);
        }

如果我添加Roles.CreateRole(role.RoleName, role.Status,role.CreatedBy,role.CreatedDate,role.ModifiedBy,role.ModifiedDate);多个参数显示错误

假设您具有枚举角色。唯一的方法是。

foreach (Role role in Enum.GetValues(typeof(Role)))
{
    Roles.CreateRole(role);
}

根据MSDS CreateRole Method (String)只接受一个参数。它没有过载。
