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

var str="  c sharp  "; str = str.Trim();
        str = Regex.Replace(str, @"\s+", " ");  ///"c sharp"

Answer 2

If you want to keep one space between every word. this should do it..

 public static string TrimSpacesBetweenString(string s)
    {
        var mystring  =s.RemoveTandNs().Split(new string[] {" "}, StringSplitOptions.None);
        string result = string.Empty;
        foreach (var mstr in mystring)
        {
            var ss = mstr.Trim();
            if (!string.IsNullOrEmpty(ss))
            {
                result = result + ss+" ";
            }
        }
        return result.Trim();

    }

it will remove the string in between the string so if the input is

var s ="c           sharp";
result will be "c sharp";

Answer 3

string myString = "C Sharp".Replace(" ", "");

Answer 4

You could use String.Replace method

string str = "C Sharp";
str = str.Replace(" ", "");

or if you want to remove all whitespace characters (space, tabs, line breaks...)

string str = "C Sharp";
str = Regex.Replace(str, @"\s", "");

Answer 5

if you want to remove all spaces in one word:

input.Trim().Replace(" ","")

And If you want to remove extra spaces in the sentence, you should use below:

input.Trim().Replace(" +","")

the regex " +", would check if there is one ore more following space characters in the text and replace them with one space.

Answer 6

I found this method great for doing things like building a class that utilizes a calculated property to take lets say a "productName" and stripping the whitespace out to create a URL that will equal an image that uses the productname with no spaces. For instance:

    namespace XXX.Models
    {
        public class Product
        {
            public int ProductID { get; set; }
            public string ProductName { get; set; }
            public string ProductDescription { get; set; }

            public string ProductImage
            {
                get { return ProductName.Replace(" ", string.Empty) + ".jpg"; }
            }
        }
    }

So in this answer I have used a very similar method as w69rdy, but used it in an example, plus I used string.Empty instead of "". And although after .Net 2.0 there is no difference, I find it much easier to read and understand for others who might need to read my code. I also prefer this because I sometimes get lost in all the quotes I might have in a code block.
