无法将特殊字符串转换为整数 [英] Can't convert special string to integer

问题描述

Hi


如何将以下字符串转换为整数或普通ASCII字符串



string input =3285 ; //3285不等于3285

int no = Convert.ToInt32（输入）;



它会抛出异常< br $>




谢谢



我尝试了什么：



string input =3285; //3285不等于3285

int no = Convert.ToInt32（输入）;



它会抛出异常

Hi
How to convert the following string to integer or to normal ASCII string

string input = "３２８５"; //"３２８５" not equal to "3285"
int no = Convert.ToInt32(input);

It will threw exception


Thanks

What I have tried:

string input = "３２８５"; //"３２８５" not equal to "3285"
int no = Convert.ToInt32(input);

It will threw exception

推荐答案

当然它会抛出异常。字符串中的每个数字之间都有空格。首先删除空格，然后使用int.TryParse进行转换。

Of course it will throw an exception. You have white space between each digit in the string. First remove the white space then use the int.TryParse to do your convertions.

引用：

/ /3285不等于3285

//"３２８５" not equal to "3285"

全部在注释中，第二个3285是由数字组成的整数，但是一个是一些看起来像数字但不是数字的unicode。

3用utf-8编码为EF BC 93

2编码为utf-8为EF BC 92

8在utf-8中编码为EF BC 98

5在utf-8中编码为EF BC 95



3也被解码为U + FF13 FULLWIDTH DIGIT THREE，这不是C＃视角的数字。



如果这是典型的数据你必须处理，你应该首先将unicode字符转换为传统数字。

All is in the comment, the second 3285 is an integer made of digits, but the one is some unicode that look like digits but is not made of digits.
the "３" is coded in utf-8 as EF BC 93
the "２" is coded in utf-8 as EF BC 92
the "８" is coded in utf-8 as EF BC 98
the "５" is coded in utf-8 as EF BC 95

the "３" is also decoded as U+FF13 FULLWIDTH DIGIT THREE, which is not a digit from the C# point of view.

If this is typical of data you have to handle, you should convert unicode chars to traditional digits first.
