asp.net C＃变量

Question

This is probably super simple and I'm sorry if I seem totally stupid but... 这可能是非常简单的，如果我看起来完全愚蠢，对不起，...

I'm coding my first asp.net web page for a class and I'm used to PHP 我正在为类编写我的第一个asp.net网页，并且习惯了PHP

in PHP when you create a variable in one block of code you can use it in all the others (as long as it has already be initialized) 在PHP中，当您在一个代码块中创建变量时，可以在所有其他代码块中使用它（只要它已被初始化）

Here is an example of what I mean: 这是我的意思的示例：

<?php $myVariable = "Hello World!" ?>

(later on in the code:) （稍后在代码中：）

<?php echo $myVariable; ?>

and In PHP that will work fine 并且在PHP中可以正常工作

Now the equivilant in asp as I understand it is: 现在，据我所知，asp中的等价物是：

<% String myVariable = "Hello World!"; %>

But when I try to use it in another block of code, the variable myVariable is not accessible 但是，当我尝试在另一个代码块中使用它时，变量myVariable无法访问

Am I doing something wrong? 难道我做错了什么？

Answer 1

The problem here is the scope of the variable. 这里的问题是变量的范围。 I would suggest you to go through this article at http://www.informit.com/articles/article.aspx?p=25467&seqNum=5 我建议您阅读http://www.informit.com/articles/article.aspx?p=25467&seqNum=5的这篇文章。
