How to trim whitespace between characters

Question

How to remove whitespaces between characters in c#?

Trim() can be used to remove the empty spaces at the beginning of the string as well as at the end.

Answer 1

Use String.Replace to replace all white space with nothing.

eg

string newString = myString.Replace(" ", "");

Answer 2

//Remove spaces from a string just using substring method and a for loop 
static void Main(string[] args)
{
    string businessName;
    string newBusinessName = "";
    int i;

    Write("Enter a business name >>> ");
    businessName = ReadLine();

    for(i = 0; i < businessName.Length; i++)
    {
        if (businessName.Substring(i, 1) != " ")
        {
            newBusinessName += businessName.Substring(i, 1);
        }
    } 

    WriteLine("A cool web site name could be www.{0}.com", newBusinessName);
}

Answer 3

If you want to keep one space between every word. You can do it this way as well:

string.Join(" ", inputText.Split(new char[0], StringSplitOptions.RemoveEmptyEntries).ToList().Select(x => x.Trim()));
