清除自定义数组 [英] Clearing a custom array

问题描述

而不是ZeroMemory API在VB.NET中使用什么来使用自定义结构来清理数组？


.clear isn' '默认是它的成员。


有什么建议吗？


谢谢，

亚当

Instead of the ZeroMemory API what would one use in VB.NET to
clean an array using a custom structure?

The .clear isn''t a member of it by default.

Any suggestions?

Thanks,
Adam

私人结构测试

公共名称为字符串

公共号码为整数


Public Sub New（_

ByVal Name As String，_

ByVal Number As Integer _

）

Me.Name = Name

Me.Number =数字

结束次级

结束结构

....

Dim a（）As Test = _

{_

New Test（Hello，12），New Test（Bla，2）_ < br $>
}

Array.Clear（a，0，a.Length）

嗯，


它不是VB.NET阵列。


这是一个结构（VB6类型），因此被放入一个数组：


结构HelloWorld

dim消息为字符串

暗日期为字符串

结束结构


public Lets尝试HellowWorld（）


它将编译如下，但在尝试运行该代码时会失败：


''在我们开始填写电子邮件帐户数组之前，请确保它很好

和清洁

Array.Clear（LetsTry，0，LetsTry.Length）


我想这是因为我是没有做{}数组格式你的例子

显示。

Hmmm,

It''s not a VB.NET array.

It''s a structure (VB6 Type) that gets put into an array hence:

Structure HelloWorld
dim Message as string
dim date as string
end structure

public LetsTry as HellowWorld()

It will compile as below but fall over when it tries to run that code:

''Before we start filling the email accounts array lets make sure it''s nice
and clean
Array.Clear(LetsTry, 0, LetsTry.Length)

I guess it''s because I''m not doing the {} array format your example below
shows.

当我尝试dec把它称为新它简单地说数组不能用

来表示新。关键词。

When I try declare it as "New" it simply says arrays cannot be delcared with
the "New" keyword.
