C#从ArrayList中删除对象

下面的代码详细演示了ArrayList如果通过各种方法删除集合内的单个或者多个对象

通过Remove方法直接删除指定的对象

ArrayList alcollect = new ArrayList();
 
// Add individual items to the collection
 
string str = "learn csharp";
alcollect.Add(str);
alcollecti.Remove(str);

通过RemoveAt方法根据索引号删除对象

ArrayList alcollect = new ArrayList();
 
// Removes first item in ArrayList
alcollect.RemoveAt(0);

RemoveRange方法根据索引范围删除对象

ArrayList alcollect = new ArrayList();
 
// Removes first four items in ArrayList
alcollect.RemoveRange(0, 4);

Clear方法直接干掉所有的对象

ArrayList alcollect = new ArrayList();
 
// Removes all objects in ArrayList
alcollect.Clear();
