blocks|key|1160848|text|使用Regex+/+MatchEvaluator路由，您可以在|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1160849|"[.:?!]\s[a-z]"|code-block|syntax|javascript|1160850|把整场比赛都资本化了。|1160851|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

Using the Regex / MatchEvaluator route, you could match on

<pre><code>"[.:?!]\s[a-z]"
</code></pre>

and capitalize the entire match.

Try this:

}|code-block|syntax|javascript|1138322|使用：|offset|length|style|BOLD|1138323|string+capitalized+=+s.CapitalizeAfter(new[]+{+'.',+':',+'?',+'!'+});|1138324|entityMap^0|0|0|0|3|0|0^^$0|@$1|2|3|4|5|6|7|Q|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|R|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|S|8|@$I|T|J|U|K|L]]|9|@]|A|$]]|$1|M|3|N|5|D|7|V|8|@]|9|@]|A|$E|F]]|$1|O|3|-4|5|6|7|W|8|@]|9|@]|A|$]]]|P|$]]

Fast and easy:

<pre><code>static class Ext
{
 public static string CapitalizeAfter(this string s, IEnumerable&lt;char&gt; chars)
 {
 var charsHash = new HashSet&lt;char&gt;(chars);
 StringBuilder sb = new StringBuilder(s);
 for (int i = 0; i &lt; sb.Length - 2; i++)
 {
 if (charsHash.Contains(sb[i]) &amp;&amp; sb[i + 1] == ' ')
 sb[i + 2] = char.ToUpper(sb[i + 2]);
 }
 return sb.ToString();
 }
}
</code></pre>

Usage:

<pre><code>string capitalized = s.CapitalizeAfter(new[] { '.', ':', '?', '!' });
</code></pre>

blocks|key|1138343|text|我使用扩展方法。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1138344|public+static+string+CorrectTextCasing(this+string+text)
{
++++//++/[.:?!]\\s[a-z]/+matches+letters+following+a+space+and+punctuation,
++++//++/%5E(?:\\s%2B)?[a-z]/++matches+the+first+letter+in+a+string+(with+optional+leading+spaces)
++++Regex+regexCasing+=+new+Regex("(?:[.:?!]\\s[a-z]%7C%5E(?:\\s%2B)?[a-z])",+RegexOptions.Multiline);

++++//++First+ensure+all+characters+are+lower+case.++
++++//++(In+my+case+it+comes+all+in+caps;+this+line+may+be+omitted+depending+upon+your+needs)++++++++
++++text+=+text.ToLower();

++++//++Capitalize+each+match+in+the+regular+expression,+using+a+lambda+expression
++++text+=+regexCasing.Replace(text,+s+=>+(s.Value.ToUpper));

++++//++Return+the+new+string.
++++return+text;

}|code-block|syntax|javascript|1138345|然后我可以做以下几件事：|1138346|string+mangled+=+"i'm+A+little+teapot,+short+AND+stout.+here+IS+my+Handle.";
string+corrected+=+s.CorrectTextCasing();
//++returns+"I'm+a+little+teapot,+short+and+stout.++Here+is+my+handle."|1138347|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|N|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|O|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|K|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|L|$]]

I use an extension method.

<pre><code>public static string CorrectTextCasing(this string text)
{
 // /[.:?!]\\s[a-z]/ matches letters following a space and punctuation,
 // /^(?:\\s+)?[a-z]/ matches the first letter in a string (with optional leading spaces)
 Regex regexCasing = new Regex("(?:[.:?!]\\s[a-z]|^(?:\\s+)?[a-z])", RegexOptions.Multiline);

 // First ensure all characters are lower case. 
 // (In my case it comes all in caps; this line may be omitted depending upon your needs) 
 text = text.ToLower();

 // Capitalize each match in the regular expression, using a lambda expression
 text = regexCasing.Replace(text, s =&gt; (s.Value.ToUpper));

 // Return the new string.
 return text;

}
</code></pre>

Then I can do the following:

<pre><code>string mangled = "i'm A little teapot, short AND stout. here IS my Handle.";
string corrected = s.CorrectTextCasing();
// returns "I'm a little teapot, short and stout. Here is my handle."
</code></pre>

blocks|key|1160876|text|其中，文本变量包含字符串。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1160877|++++++++string+text+=+"I+ate+something.+but+I+didn't:+instead,+no.+what+do+you+think?+i+think+not!+excuse+me.moi";

Where the text variable contains the string

<pre><code> string text = "I ate something. but I didn't: instead, no. what do you think? i think not! excuse me.moi";
 string[] punctuators = { "?", "!", ",", "-", ":", ";", "." };
 for (int i = 0; i&lt; 7;i++)
 {
 int pos = text.IndexOf(punctuators[i]);
 while(pos!=-1)
 {
 text = text.Insert(pos+2, char.ToUpper(text[pos + 2]).ToString());
 text = text.Remove(pos + 3, 1);
 pos = text.IndexOf(punctuators[i],pos+1);
 }
 }
</code></pre>

I'm trying to find an efficient way to take an input string and capitalize the first letter after every punctuation mark (<code>. : ? !</code>) which is followed by a white space.

Input: 

<blockquote>
 "I ate something. but I didn't:
 instead, no. what do you think? i
 think not! excuse me.moi"
</blockquote>

Output: 

<blockquote>
 "I ate something. But I didn't:
 Instead, no. What do you think? I
 think not! Excuse me.moi"
</blockquote>

The obvious would be to split it and then capitalize the first char of every group, then concatenate everything. But it's uber ugly. What's the best way to do this? (I'm thinking <code>Regex.Replace</code> using a <code>MatchEvaluator</code> that capitalizes the first letter but would like to get more ideas)

Thanks!
