如何使用bool contains打印出排序列表中的项和键的值？我只想打印出那个匹配钥匙的那个。提前致谢！

正如你所说，我宣布了排序列表中我有一个类，而一个艺术家的密钥来自gui的文本文本。

我们这样说

   string artsearch = something;
   bool contains = list.ContainsKet(artsearch);    
   SortedList<string, Artist> list = new SortedList<string, Artist>();
    Artist a = new Artist(artist, members, albm1);
        a.Name = artist;
        a.Members = members;
        list.Add(artist, a);

   public class Artist : IComparable
{
    public string name;
    public string members;
    public string album;
    public Guid artistID;
    public LinkListGen<string> albums;

    public Artist()
    {
        artistID = new Guid();
    }

    public Artist(string name, string members, LinkListGen<string> albums)
    {
        this.name = name;
        this.members = members;
    }

    public string Name
    {
        get { return name; }
        set { name = value; }
    }

    public string Albums
    {
        get { return album; }
        set { album = value; }
    }


    public string Members
    {
        get { return members; }
        set { members = value; }
    }



    public int CompareTo(object obj)
    {
        if (obj is Artist)
        {
            Artist other = (Artist)obj;
            return name.CompareTo(other.name);
        }
        if (obj is string)
        {
            string other = (string)obj;
            return members.CompareTo(other);
        }
        else
        {
            return -999;
        }
    }

}

您可以使用索引器获取值：

if(contains)
{
   Console.WriteLine("{0} -> {1}", artsearch, list[artsearch]);
}

您可以使用TryGetValue：

组合这些内容

Artist value;
if(list.TryGetValue(artsearch, out value))
{
    Console.WriteLine("{0} -> {1}", artsearch, value);
}

请注意，这适用于任何实现IDictionary<TKey, TValue>的类，而不仅仅是SortedList<TKey, TValue>。
