C# : Adding items to comboBox error

Question

我有一个 League.cs 文件，其中包含一个项目的所有联赛

当我尝试在组合框中显示此数据时，它显示“App.Toolkit.Parameter”而不是联赛名称。

我将这段代码用于组合:

foreach (League item in League.GetAll()) { comboBox1.Items.Add(item); }

和 league.cs 文件:

using System.Collections.Generic;

namespace App.Toolkit.Parameter
{
    public class League : SearchParameterBase<uint>
    {
        public const uint BarclaysPremierLeague = 13;

        public const uint Bundesliga = 19;

        public const uint LigaBbva = 53;

        public const uint Ligue1 = 16;

        public const uint SerieA = 31;

        private League(string description, uint value)
        {
            Description = description;
            Value = value;
        }

        public static IEnumerable<League> GetAll()
        {
            yield return new League("Barclays Premier League", BarclaysPremierLeague);
            yield return new League("Bundesliga", Bundesliga);
            yield return new League("Liga BBVA", LigaBbva);
            yield return new League("Ligue 1", Ligue1);
            yield return new League("Serie A", SerieA);
        }
    }
}

感谢副词:)

Answer 1

您可以设置 ComboBox 的 DisplayMember:

comboBox1.DisplayMember = "Description";

或者您可以在您的 League 类中覆盖 ToString:

public override string ToString()
{
 return Description;
}
