Remove spaces

[shapper]

Hello,

I have the following string:

str = " string , hello,something ,new object, london city "

How can I remove all the spaces before and after a comma but never the
ones between words?

So I get my string as follows:
str = "string,hello,something,new object,london city"

Thanks,

Miguel

I'm sure there are much cleverer and more efficient ways of doing this,
maybe with Regular Expressions, but the following will do it for you:

string str = " string , hello,something ,new object, london city ";
while (str.Contains(" ,"))
{
str = str.Replace(" ,", ",");
}
while (str.Contains(", "))
{
str = str.Replace(", ", ",");
}
str = str.Trim();
