清除数组 [英] Clearing arrays
问题描述
有谁知道如何清除阵列？我的C＃书谈了
关于创建数组或谈论使用Clear或
RemoveAt但这些方法似乎不可用
for我的数组。
我有一组客户端对象叫aClients
如果我试试aClients.Remove我得到一个错误
" System.Array"不包含定义
forRemoveAt。
如果我尝试aClients.Clear（）我收到错误
方法中没有过载清除取0参数
有GUI博士关于使用数组的文章在.NET中称为
" Dr。 GUI .NET＃7
Conway'作为Windows窗体应用程序的生命游戏
您可以在MSDN Library上找到这篇文章。 />

我有一个名为aClients的客户端对象数组
如果我尝试aClients.RemoveAt我收到错误
System.Array对于RemoveAt不包含定义
。
如果我尝试aClients.Clear（）我收到错误
方法没有重载清除取0参数
这本书正在谈论ArrayList
ArrayList aClients = new ArrayList（）;
aClients.Add（client1）;
aClients.Add（client2）;
aClients.Add（ client3）;
aClients.Remove（client3）;
aClients.RemoveAt（0）;
aClients.Clear（） ;

你确定他们在讨论数组而不是ArrayLists吗？很难在阵列上使用这些操作。
我有一组客户端对象叫做aClients
如果我试试aClients。删除我收到错误
System.Array不包含RemoveAt的定义
。
如果我尝试aClients.Clear（）我收到错误
方法没有重载清除取0参数
从数组中删除项目（或清除数组）并不是真的有意义，因为数组有固定的长度。但是，您*可以*通过
执行此操作，首先输入IList类型的引用 - Array使用显式接口实现实现各种各样的IL $成员。

Does anyone know how to clear arrays? My C# books talk
about creating arrays or talk about using Clear or
RemoveAt but these methods don''t appear to be available
for my array.
I have an array of client objects called aClients
if I try aClients.RemoveAt I get an error
"System.Array" does not contain a definition
for "RemoveAt".
if I try aClients.Clear() I get an error
No overload for method "Clear" takes "0" Arguments
Hi,
There''s a Dr. GUI''s article on using arrays in .NET called
"Dr. GUI .NET #7
Conway''s Game of Life as a Windows Forms Application"
You can find this article on the MSDN Library.

The book is talking about ArrayList
ArrayList aClients = new ArrayList();
aClients.Add(client1);
aClients.Add(client2);
aClients.Add(client3);
aClients.Remove(client3);
aClients.RemoveAt(0);
aClients.Clear();

Are you sure they''re talking about arrays rather than ArrayLists? It''s
rare to use those operations on arrays.
I have an array of client objects called aClients
if I try aClients.RemoveAt I get an error
"System.Array" does not contain a definition
for "RemoveAt". if I try aClients.Clear() I get an error

Removing an item from an array (or clearing the array) doesn''t really
make sense, as arrays have fixed lengths. However, you *can* do it by
casting the reference to type IList first - Array implements various
IList members using explicit interface implementation.
