自定义FxCop规则来检查MVC应用程序中的属性

Question

是否有一个合理的简单的方法来让FxCop检查是否有任何使用ViewBag, ViewData在MVC应用程序

Answer 1

最简单的方法是筛选名称为"ViewBag"或"ViewData"(带有get_和set_前缀)的MemberBinding实例。这可能会导致相当多的误报，因此下一个复杂性/完整性级别将是检查MemberBinding目标的类型，看看它是视图还是控制器。例如:

private readonly string[] _forbiddenNames = new string[] { "get_ViewBag", "set_ViewBag", "get_ViewData", "set_ViewData" };
public override ProblemCollection Check(Member member)
{
    var method = member as Method;
    if (method != null)
    {
        this.Visit(method.Body);
    }
    return this.Problems;
}
public override void VisitMemberBinding(MemberBinding memberBinding)
{
    base.VisitMemberBinding(memberBinding);
    var memberName = memberBinding.BoundMember.Name.Name;
    if (this._forbiddenNames.Contains(memberName))
    {
        this.Problems.Add(new Problem(this.GetResolution(memberBinding.BoundMember), memberBinding, memberName));
    }
}
