我有一个具有以下属性的电影对象
public class Movie {
private string title;
...other similar properties...
}
如何实现在二叉树中使用的CompareTo（）类？
我到目前为止所做的是
public int CompareTo(object obj)
{
Movie m1 = (Movie)obj;
return this.title.CompareTo(m1.title);
}
By trying to use the pre-existing CompareTo() function in string, but it won't work.
这就是实现CompareTo的方式
static void Main(string[] args)
{
var m1 = new Movie() { title = "a1" };
var m2 = new Movie() { title = "a0" };
if (m1.CompareTo( m2) == 0)
{
Console.WriteLine("equal");
}
else
{
Console.WriteLine("not equal");
}
}
public class Movie: IComparable
{
public string title;
public int CompareTo(object obj)
{
Movie m1 = (Movie)obj;
return this.title.CompareTo(m1.title);
}
}
