什么是这个奇怪的VB语法的c#等价物？

Question

我发现以下语法作为VB.NET属性,我试图将其转换为c#,但我不知道如何实现.

Public Property SomeText(ByVal someEnumThing as SomeEnum) As String
    Get
        Select Case someEnumThing
            //figure out what string to return
        End Select
    End Get
    Set(ByVal Value as String)
        Select Case someEnumThing
            //figure out what string to set
        End Select
    End Set
End Property

我以前从未见过这样的房产,有什么想法吗？

我想你是指这个属性的论据.好吧,据我所知,C#只支持索引器,它们没有名称(例如this[SomeEnum someEnumThing] {}).

如果要获得类似的行为,可以创建一个带有索引器属性的帮助器类,并使用它来公开属性的"名称":

public class YourClass {
    public struct SomeTextProperty {
        private readonly YourClass owner;

        internal SomeTextProperty(YourClass owner) {
            this.owner = owner;
        }

        public string this[SomeEnum someEnumThing] {
            get {
                return owner.GetSomeText(someEnumThing);
            }
            set {
                owner.SetSomeText(someEnumThing, value);
            }
        }
    }

    public SomeTextProperty SomeText {
        get {
            return new SomeTextProperty(this);
        }
    }

    private string GetSomeText(SomeEnum someEnumThing) {
        // implementation to get it
    }

    private void SetSomeText(SomeEnum someEnumThing, string value) {
        // implementation to set it
    }
}
