Need C# Regex for replacing spaces inside of strings

Using C#, I need a some code to use regular expressions to replace spaces inside of quotes with a pipe character (|). problem is that the string could contain multiple quoted expressions and I only want the spaces inside of quotes .

I tried a few things but I am struggling with how to handle the variable number of words that could be inside of quotes, amongst other things.

Here is some examples of what may be input, and the required output:

"word1 word2"
-> "word1|word2"

"word1 word2" word3 "word4 word5"
-> "word1|word2" word3 "word4|word5"

word1 "word2 word3"
-> word1 "word2|word3"

Any help greatly appreciated, and hopefully I will learn about regular expressions.

使用正则表达式查找引号，并使用普通的替换来替换空格：

str = Regex.Replace(str, @"""[^""]+""", m => m.Value.Replace(' ', '|'));

There is a helpful webiste to test stuff like this, it's called reFiddle

What i would do is to use this

http://refiddle.com/288

/["][^"]+["]/g

To get the strings that are inside of quotes, then just do a replace on those returned strings, and you should be golden.
