Question

我正在制作一个项目，我必须与房间相互比较，如果房间有变化则打印。

我制作了这段代码，工作正常。但代码真的很难看，我想优化代码。有没有办法可以将变量收集在一起，所以我没有14行变量？也许我以后必须使用变量，所以我不想内联变量。

<th class="callout-inner secondary no-changes-reservation-bgcolor">
    <h5>Reservationsnummer:</h5>

        @{
            var orderfirstName = Model.Order.FirstName.ToString();
            var order2firstName = Model.Order2.FirstName.ToString();
            var orderlastName = Model.Order.LastName.ToString();
            var order2lastName = Model.Order2.LastName.ToString();
            var orderaddress = Model.Order.Address.ToString();
            var order2address = Model.Order2.Address.ToString();
            var orderpostCode = Model.Order.PostCode.ToString();
            var order2postCode = Model.Order2.PostCode.ToString();
            var orderCity = Model.Order.City.ToString();
            var order2City = Model.Order2.City.ToString();
            var orderPhone = Model.Order.Phone.ToString();
            var order2Phone = Model.Order2.Phone.ToString();
            var orderEmail = Model.Order.Email.ToString();
            var order2Email = Model.Order2.Email.ToString();
        }
        <table align="center" class="wrapper header float-center">
            <tr>
                <td class="wrapper-inner background-color__yellow">
                    <span>
                        @renderOrderPropertyBlock("Fornavn", orderfirstName, order2firstName)
                        <br />
                        @renderOrderPropertyBlock("Efternavn", orderlastName, order2lastName)
                        <br />
                        @renderOrderPropertyBlock("Adresse", orderaddress, order2address)
                        <br />
                        @renderOrderPropertyBlock("Postnummer", orderpostCode, order2postCode)
                        <br />
                        @renderOrderPropertyBlock("City", orderCity, order2City)
                        <br />
                        @renderOrderPropertyBlock("Phone", orderPhone, order2Phone)
                        <br />
                        @renderOrderPropertyBlock("Email", orderEmail, order2Email)
                    </span>
                </td>
            </tr>
        </table>
     </th>

Answer 1

您不必将这些变量，简单传递属性值定义到您的html帮助器：

@renderOrderPropertyBlock("Fornavn", Model.Order.FirstName.ToString(), Model.Order2.FirstName.ToString())

您还可以使用反射迭代属性，但代码执行速度会慢得多。

Answer 2

你可以这样做：

@{
     var order1 = Model.Order;
     var order2 = Model.Order2;
}

在你的范围内：

<span>
      @renderOrderPropertyBlock("Fornavn", order1.FirstName.ToString(), order2.FirstName.ToString())
      <br />

// and so on ...

</span>

收集变量并缩短代码
