你直接传一个数组进去，而且是一个结构体数组，array.sort怎么知道根据结构中的哪一个属性进行排序？放一个c#的代码你看看，VB和C#很相似的
class Program
{
static void Main(string[] args)
{
People[] p = new People[3]
{
new People{name="张三"},
new People{name="李四"},
new People{name="张二名"}
};
//重点传一个实现了IComparer接口的类进去，告诉Array.Sort怎么排序
Array.Sort(p, new PeopleCompare());
foreach (var item in p)
{
Console.WriteLine(item.name);
}
Console.ReadKey();
}
}
//People结构体，换成类一样的
public struct People
{
public string name { get; set; }
}
//实现了IComparer接口的类
public class PeopleCompare : IComparer
{
public int Compare(object x, object y)
{
People p1 = (People)x ;
People p2 = (People)y;
return p1.name.CompareTo(p2.name);
}
}
