你可以做一个foreach通过字符串 - foreach（char中的a） - 或者做
a for循环并使用字符串'的索引器。无论哪种方式，您都可以检查每个

字符，并将Char.ToUpper（）应用于

空格（Char.IsWhiteSpace（））之后的任何字符。你不能修改

的单个字符当然不会创建一个新的字符串，这不是有效的;

你可能想要将每个字符附加到一个StringBuilder并在例程结束时返回

StringBuilder的ToString（）。或者，将字符串转换为字符数组可能会更快
，调整必要的

字符，然后将其转换回字符串。你的里程数

可能会因典型的字符串长度而有所不同。


另一种方法可能是使用string的split（）方法将其转换为

成一个字符串数组的单词，每个单词都是正确的情况，然后将它们放回原来

一起变成一个字符串。这在概念上很简单，但如果你想要调用这个例程，可能会太慢。


最后，可以构造一个正则表达式做一些或全部这个

工作。

You could do a foreach through the string -- foreach (char c in a) -- or do
a for loop and use the string''s indexer. Either way you can examine each
character that way and apply Char.ToUpper() to any character following
whitespace (Char.IsWhiteSpace()). You can''t modify individual characters of
the string of course without creating a new string, which isn''t efficient;
you might want to append each character to a StringBuilder and return the
StringBuilder''s ToString() at the end of the routine. Or, it might be
faster to convert the string to a character array, tweak the necessary
characters, and then convert it back to a string at the end. Your mileage
will likely vary depending on typical string lengths.

Yet another approach might be to use the Split() method of string to turn it
into a string array of words, proper case each word, then put them back
together into a string. That is conceptually simple but may be too slow if
you''re going to call this routine alot.

Finally, a regular expression could be constructed to do some or all of this
work.

如果你是使用VB.Net，查看StrConv（）函数及其转换

参数。根据文档，VbStrConv.ProperCase将每个单词的大写字母

。


我不知道C＃等价物。

If you''re using VB.Net, check out the StrConv() function and its Conversion
argument. VbStrConv.ProperCase, according to the docs, capitalizes each word
of a string.

I''m not aware of a C# equivalent.
