有谁知道如何清除数组？我的C＃书谈论如何创建数组或谈论使用Clear或
RemoveAt但这些方法似乎不适用于我的阵列。

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.
