復制代碼 代碼如下:

Person p1 = new Person( " " , 18 );
Person p2 = new Person( " " , 19 );
Person p3 = new Person( " " , 20 );
Person[] persons = ... { p1, p2, p3 } ;
// 查找p2所在數組中的位置
Array.IndexOf < Person > (persons, p2);

復制代碼 代碼如下:

Person p1 = new Person( " " , 18 );
Person p2 = new Person( " " , 19 );
Person p3 = new Person( " blog.my400800.cn/400電話 " , 20 );
Person[] persons = ... { p1, p2, p3 } ;
Person p4 = new Person(p2.Name, p2.Age);
// 查找數組中與p4相同的元素所在的位置
Array.IndexOf < Person > (persons, p4);

復制代碼 代碼如下:

public override bool Equals( object obj)
... {
Person person = obj as Person;
if (person == null ) return false ;
return ( this .name == person.name && this .age == person.age);
}

復制代碼 代碼如下:

public int CompareTo( object obj)
... {
Person person = obj as Person;
if (person == null )
throw new Exception( " The method or operation is not implemented. " );
// 先從年齡開始比較
int ageResult = this .age.CompareTo(person.age);
if (ageResult == 0 )
... {
// 如果年齡相等在坐姓名比較
return this .name.CompareTo(person.name);
}
else
... {
return ageResult;
}
}

復制代碼 代碼如下:

// 得到 person 在 persons 中有相同值的下標
// 如果多個相同的值,BinarySearch將取最后
// 一個有相同值的數組下標
Array.BinarySearch < Person > (persons, person);

復制代碼 代碼如下:

// 必需使比較的對象實現IComparable接口
Array.Sort < Person > (persons);
