Hi,
Could anyone tell me how to remove the multiple spaces in a string

Hi bluesky,

Use the regular expression to remove multiple spaces in a string

// i have a variable amount of spaces between each word in this string
string test = "Womens and mens in a palace";
// replaces runs of multiple spaces with a single space
test = Regex.Replace(test, @"\s{2,}", " ");
// displays new string
MessageBox.Show(test);

I hope this would help for u

removing double-spaces from strings
// input string
string s = "blah blah";
// temporary for holding the string prior to replacing
string olds;

// repeatedly replace strings of 2 spaces with a single space
// until the result after replacement is the same as before,
// which implies that all spaces must be single spaces
do {
olds = s;
s = s.Replace(" ", " ");
} while (olds != s);
// now, s == "blah blah"

What bothers me about this solution is that it would be rather inefficient, particular for long strings, due to the way the .Net runtime deals with strings (given my current understanding anyway.) Some sort of StringBuilder or char array solution would probably be better I think.

public static string RemoveWhiteSpace(string line)
{
return Regex.Replace(line, "\\s+", " ");
}

private void button5_Click(object sender, EventArgs e)
{
string line = "This is ksdfj an example.";
Content.Text = Form1.RemoveWhiteSpace(line);
}
