blocks|key|760396|text|答案是查看Unicode+Code+Charts+-您将在其中找到Latin-1+supplement+chart；这表明U%2B00A0+(根据您的标题是160，而不是根据主体是167+)是一个不间断的空格。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|760397|entityMap|0|LINK|mutability|MUTABLE|url|http://unicode.org/charts|1|http://www.unicode.org/charts/PDF/U0080.pdf^0|5|J|0|X|O|1|0^^$0|@$1|2|3|4|5|6|7|N|8|@]|9|@$A|O|B|P|1|Q]|$A|R|B|S|1|T]]|C|$]]|$1|D|3|-4|5|6|7|U|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]|L|$5|G|H|I|C|$J|M]]]]

The answer is to look in <a href="http://unicode.org/charts" rel="noreferrer">Unicode Code Charts</a> - where you'll find the <a href="http://www.unicode.org/charts/PDF/U0080.pdf" rel="noreferrer">Latin-1 supplement chart</a>; this shows that U+00A0 (160 as per your title, not 167 as per the body) is a non-breaking space.

Maybe you could to use a regex to replace those empty chars:

<pre><code>Regex.Replace(input, @"\p{Z}", "");
</code></pre>

This will remove <a href="http://www.regular-expressions.info/unicode.html" rel="noreferrer">"any kind of whitespace or invisible separator"</a>.

This is a fast (and fairly readable) way of removing any characters classified as white space using <a href="http://msdn.microsoft.com/en-us/library/t809ektx.aspx" rel="nofollow noreferrer"><code>Char.IsWhiteSpace</code></a>:

<pre><code>StringBuilder sb = new StringBuilder (value.Length);
foreach (char c in value)
{
 if (!char.IsWhiteSpace (c))
 sb.Append (c);
}
string value= sb.ToString();
</code></pre>

As <a href="https://stackoverflow.com/users/253984/dbemerlin">dbemerlin</a> points out, if you know you will only need numbers from your data, you would be better use <a href="http://msdn.microsoft.com/en-us/library/yk2b3t2y.aspx" rel="nofollow noreferrer"><code>Char.IsNumber</code></a> or the even more restrictive <a href="http://msdn.microsoft.com/en-us/library/7f0ddtxh.aspx" rel="nofollow noreferrer"><code>Char.IsDigit</code></a>:

<pre><code>StringBuilder sb = new StringBuilder (value.Length);
foreach (char c in value)
{
 if (char.IsNumber(c))
 sb.Append (c);
}
string value= sb.ToString();
</code></pre>

If you need numbers and decimal seperators, something like this should suffice:

<pre><code>StringBuilder sb = new StringBuilder (value.Length);
foreach (char c in value)
{
 if (char.IsNumber(c)|c == System.Globalization.NumberFormatInfo.CurrentInfo.NumberDecimalSeparator )
 sb.Append (c);
}
string value= sb.ToString();
</code></pre>

blocks|key|987708|text|使用扩展方法的解决方案：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|987709|public+static+class+ExtendedMethods

blocks|key|759883|text|用Rubens已经发布的Regex方法替换所有的空字符(这也是提问者想要做的)，不是更好的方法吗？|type|unstyled|depth|inlineStyleRanges|entityRanges|data|759884|Regex.Replace(input,+@"\p{Z}",+"");|code-block|syntax|javascript|759885|或者Expresso的建议：|759886|Regex.Replace(input,+@"\p{Zs}",+"");|759887|这里的不同之处在于，\p{Z}替换任何类型的空格或不可见分隔符，而\p{Zs}替换不可见的空格字符，但会占用空间。您可以在此处阅读(+Unicode类别一节)：|759888|http://www.regular-expressions.info/unicode.html|offset|length|759889|使用RegEx的好处是，只需要一个命令就可以替换正常的空格，而不仅仅是上面一些答案中解释的不间断空格。|759890|如果只考虑性能，那么当然应该考虑其他方法，但这超出了本文的讨论范围。|759891|entityMap|0|LINK|mutability|MUTABLE|url^0|0|0|0|0|0|0|1C|0|0|0|0^^$0|@$1|2|3|4|5|6|7|11|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|12|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|13|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|14|8|@]|9|@]|A|$E|F]]|$1|K|3|L|5|6|7|15|8|@]|9|@]|A|$]]|$1|M|3|N|5|6|7|16|8|@]|9|@$O|17|P|18|1|19]]|A|$]]|$1|Q|3|R|5|6|7|1A|8|@]|9|@]|A|$]]|$1|S|3|T|5|6|7|1B|8|@]|9|@]|A|$]]|$1|U|3|-4|5|6|7|1C|8|@]|9|@]|A|$]]]|V|$W|$5|X|Y|Z|A|$10|N]]]]

Wouldn't be the preferred method to replace all empty characters (and this is what the questioner wanted to do) with the Regex Method which Rubens already posted?

<pre><code>Regex.Replace(input, @"\p{Z}", "");
</code></pre>

or what Expresso suggests:

<pre><code>Regex.Replace(input, @"\p{Zs}", "");
</code></pre>

The difference here is that \p{Z} replaces any kind of whitespace or invisible separator whereas the \p{Zs} replaces a whitespace character that is invisible, but does take up space.
You can read it here (Section Unicode Categories):

<a href="http://www.regular-expressions.info/unicode.html" rel="nofollow">http://www.regular-expressions.info/unicode.html</a>

Using RegEx has the advantage that only one command is needed to replace also the normal whitespaces and not only the non-breaking space like explained in some answers above.

If performance is the way to go then of course other methods should be considered but this is out of scope here.

I am formatting numbers to string using the following format string "# #.##", at some point I need to turn back these number strings like (1 234 567) into something like 1234567. I am trying to strip out the empty chars but found that 

<pre><code>value = value.Replace(" ", ""); 
</code></pre>

for some reason and the string remain 1 234 567. After looking at the string I found that 

value[1] is 160. 

I was wondering what the value 160 means?

What does char 160 mean in my source code?

我使用以下格式字符串"# #.##“将数字格式化为字符串，在某些情况下，我需要将这些数字字符串( 1234567 )转换为类似于1234567的内容。我试着去掉空字符，但发现value = value.Replace(" ", "");  由于某种原因，字符串仍然是1 234 567。在查看字符串后，我发现value1是160。我想知道160这个值是什么意思？
