C# - Convert Multiple Spaces into Single Spaces within a string

[cyberdrugs]

Hi guys 'n gals,

I have a string which contains multiple spaces, and I would like to convert the multiple spaces into single spaces.

Example Input:
the quick brown fox jumps over the lazy dog

Example Output:
the quick brown fox jumps over the lazy dog

Anybody able to help me out please?

Ah, when I went to quote you, I realized that you actually intended there to be noticable differences between the two strings. Reading it on the post was decieving...

Have you tried

InputString.Spl it(' ');

And then looked at what it returns? I believe you will get a lot of strings that return true when passed through:

String.IsNullOr Empty(InputStri ng.Split(' ')[indexToBeChecke d]);

And if so, you can just pull out the strings that actually have something in them (the words) and then put it back together with a space in between each one.

I was able to accomplish this two different ways:

string initstring = "the  quick brown   fox          jumped.";
string rn = initstring.Replace("  ", " ");
while (rn.IndexOf("  ") > -1)
{
    rn = rn.Replace("  ", " ");
}
//rn now contains only single spaces
 
string[] bits = initstring.Split(" ".ToCharArray(),StringSplitOptions.RemoveEmptyEntries );
string sn = "";
foreach (string bp in bits)
{
    if (sn != "")
       sn += " ";
    sn +=bp.Trim();
}
//sn now contains only single spaces

Hi TRScheel,

I'd prefer not to have to break the string apart to get what I am after if possible...


Hi Plater,

Just tried for you first solution, and it does the charm, and it's quite fast as well (at least for what I am doing)


Thanks for the replies! :o)

Ya, after looking at Plater's solution, it is much more elegant.
