c# - IComparable 需要对列进行排序

Question

我的 DevExpress xtragrid 中的一列没有排序、分组或过滤。类似问题的答案表明我需要实现 IComparable，但当我这样做时，它根本不再显示在列中。

public class Flow : System.IComparable<Flow>
{
  public Flow(int id, string name, string description)
  {
    this.ID = id;
    this.Name = name;
    this.Description = description;
  }

  public int ID { get; private set; }

  public string Name { get; private set; }

  public string Description { get; private set; }

  public override string ToString()
  {
    return Name;
  }

  public override bool Equals(object obj)
  {
    Flow flow = obj as Flow;
    if (flow == null) return false;
    return this.ID == flow.ID;
  }

  public static bool operator ==(Flow flow1, Flow flow2)
  {
    if (object.ReferenceEquals(null, flow1))
      return object.ReferenceEquals(null, flow2);
    return flow1.Equals(flow2);
  }

  public static bool operator !=(Flow flow1, Flow flow2)
  {
    return !(flow1 == flow2);
  }

  public override int GetHashCode()
  {
    return ID;
  }

  public int CompareTo(Flow other)
  {
    return this.Name.CompareTo(other.Name);
  }
}

我做错了什么？

消失的内容是一个不相关的问题 - 转移注意力。一旦我实现了 IComparable，该列就允许排序而不是 IComparable<Flow>

public int CompareTo(object obj)
{
  if (object.ReferenceEquals(null, obj))
    return 1;
  Flow flow = obj as Flow;
  if (flow == null)
    throw new ArgumentException("Object is not of type Flow");
  return this.Name.CompareTo(flow.Name);
}
