I want to remove all space in a string;
I use :

sMyString="a b c";

sMyString=sMyString.Replace(' ',null);

But it fail when compiling.

How can I do that?

That won't work, as '' isn't a character. In this case, the OP wants (I
believe) to replace the existence of a character with *no* character at
all - so you need to use strings instead. See Chad's reply for how to
do it.
 
In addition to Jon's and Chad's replies, rather that using the double quotes
to represent an empty string, it would be better practice to use
string.Empty as thus...

newString = originalString.Replace(" ", string.Empty);

There is no real difference between the two methods Except readability of
code (and potential for accidental typos -i.e. spaces between quotes).

Br,

Mark.

I think its is strongly a matter of personal preference, both are certainly fine. Most of use have
been using "" for 10, or even 20 years as an empty string. I can see your point that it could be goofed
up, but to be honest I have never ever had a bug because of this. "" is pretty easy to spot.

Likewise - I'm definitely a fan of "" over String.Empty.
