阅读文字 [英] reading in text

问题描述

我想知道是否可以在文本文件中读取其他数据类型，而不是字符串。我想把它读作某种处理数字的类型，

就像是double，或者浮动。

像double或float。

你把每个部分都读成一个字符串（或者整行作为一个字符串，然后

分解），然后调用适当的Parse方法（或

Doule.TryParse）。

我的问题是它无法在我的机器上运行。我不知道

为什么，但是在解析文本时我的代码运行不正确。

我让其他人运行的代码完全相同它适用于

但不适合我。出于某种原因，当我解析文本时，我仍然得到空值的b $ b。但就像我说的那样，完全相同的代码，复制和粘贴，对其他人的工作方式不同。所以我试图找出如何解决这个问题。

你不能得到一个空的东西。一个int或一个double的值。


你能发一个简短但完整的程序来演示

问题，即使它只是在你的电脑？

I was wondering if it is possible to read in a text file as a data type other
than string. I would like to read it in as some type that handles numbers,
like double, or float.

You read each part as a string (or a whole line as a string and then
break it up), and then call the appropriate Parse method (or
Doule.TryParse).

My problem with that is that it is not working on my machine. I do not know
why, but my code is not running correctly when it comes to parsing the text.
I have had other people run the exact same code that I have and it works for
them but not for me. For some reason when I parse the text, I still get
empty values. But like I said, the exact same code, copied and pasted, works
differently for other people. So I am trying to find out how to get around
this problem.

You can''t get an "empty" value for an int or a double though.

Could you post a short but complete program which demonstrates the
problem, even if it only demonstrates it on your computer?

See http://www.pobox.com/~skeet/csharp/complete.html for details of
what I mean by that.
