Question

在下面的代码中，我在min = 0, max = 99方法中重复了Html.EditorFor()个值。使其更干燥的最佳方法是什么？

<div id="Team1PlayerScores">
    @for (int i = 0; i < Model.Team1.Players.Count; i++)
    {
        @Html.DisplayFor(m => Model.Team1.Players[i].Name)
        @Html.EditorFor(m => Model.Team1.Players[i].GoalsForCurrentGame, new { htmlAttributes = new { min = 0, max = 99, onchange = "updateTeamScore('Team1PlayerScores', 'Team1_GoalsForCurrentGame')" } })
    }
</div>

<div id="Team2PlayerScores">
    @for (int i = 0; i < Model.Team2.Players.Count; i++)
    {
        @Html.DisplayFor(m => Model.Team2.Players[i].Name)
        @Html.EditorFor(m => Model.Team2.Players[i].GoalsForCurrentGame, new { htmlAttributes = new { min = 0, max = 99, onchange = "updateTeamScore('Team2PlayerScores', 'Team2_GoalsForCurrentGame')" } })
    }
</div>

如果您要删除代码中“魔术数字”的重复项，而不是生成的HTML，则可以用模型中的值替换数字：

\b(?<![.\d])([1-9][0-9]{1,2}\.[1-9]|[1-9][0-9]{1,2})(?=inch)

对视图进行更新以利用它：

public class IndexModel
{
    public Team Team1 { get; set; }
    public Team Team2 { get; set; }

    public int MinimumGoals => 0;
    public int MaximumGoals => 99;
}

我已将值作为只读属性放入，但是如何将其实现到模型中由您决定。
