Question

I would like to insert a soft hyphen between every letter in a word using C#. for example here is some text:

Thisisatest => T-h-i-s-i-s-a-t-e-s-t

‘-‘ is a soft hyphen. How might i do this in C#? I am going to use it in website.

Note: I am on .NET 2.0.

Answer 1

Use the HTML entity ­ for a soft hyphen:

theString = String.Join("­", theString.Select(c => c.ToString()));

For .NET 2.0:

string[] chars = new string[theString.Length];
for (int i = 0; i < theString.Length; i++) {
  chars[i] = theString[i].ToString();
}
theString = String.Join("&shy;", chars);

Or using a StringBuilder:

StringBuilder builder = new StringBuilder(theString.Length * 6);
foreach (char c in theString) {
  builder.Append(c).Append("­");
}
theString = builder.ToString(0, builder.Length - 5);
