int.Parse（）与领先的零

问题描述

我如何prevent的code从下方投掷出现FormatException 。我希望能够分析具有前导零的字符串转换为整数。有没有干净的方式做到这一点？

 字符串值=01;
INT I = int.Parse（值）;
 

解决方案

您code运行对我来说，没有一个出现FormatException （一旦你正确把握方法）

 字符串值=01;
INT I = int.Parse（值）;
 

但这环的老钟;一个问题，我几年前，微软接受反的Windows（不是.NET）的本地化组件的错误。为了测试是否你看到的是，运行此code，让我们知道你是否得到一个出现FormatException：

 字符串值=0; //只是一个零
INT I = int.Parse（值）;
 

修改：这里是从新闻组我的文章，从早在2007年看症状是否符合你的

...和这里的有关问题在Microsoft Connect上报告：

How do I prevent the code below from throwing a FormatException. I'd like to be able to parse strings with a leading zero into ints. Is there a clean way to do this?

string value = "01";
int i = int.Parse(value);

解决方案

Your code runs for me, without a FormatException (once you capitalize the method properly):

string value = "01";
int i = int.Parse(value);

But this does ring an old bell; a problem I had years ago, which Microsoft accepted as a bug against localization components of Windows (not .NET). To test whether you're seeing this, run this code and let us know whether you get a FormatException:

string value = "0"; // just a zero
int i = int.Parse(value);

EDIT: here's my post from Usenet, from back in 2007. See if the symptoms match yours.
