在C＃中使用软连字符

Question

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

Thisisatest => Thisisatest

'-' 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);

Answer 2

No LINQ required (but .NET 4.0 needed for the object[] overload in String.Join ):

var test = "Thisisatest";
String.Join("­", test.ToCharArray());

For poor souls on previous versions:

String.Join("­", test.Select(x => x.ToString()));

If you happen to use .NET 2.0 (as the OP has now stated), then please see another response as it doesn't need to be typed again.

Answer 3

try this

.net 3.5

Console.WriteLine( String.Join("­","Thisisatest".ToCharArray().Select(r=>r.ToString()).ToArray()));

.net 4.0+

Console.WriteLine(String.Join("­", "Thisisatest".ToCharArray()));

Answer 4

Below is a simple helper method that you can use to add the hyphen between each letter for a given string.

    static string Hyphenify(string text)
    {
        return string.Join("-", text.ToArray());
    } 

You could also add another parameter to enable you to give the separator to use, see below.

    static string SpaceLetters(string text, string separator)
    {
        return string.Join(separator, text.ToArray());
    } 

Answer 5

here is the solution: ASPX page:

<asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent">
    <asp:TextBox ID="txtOriginalString" runat="server"></asp:TextBox>
    <asp:TextBox ID="txtFormattedString" runat="server"></asp:TextBox>
    <asp:Button ID="btnFormat" Text="Format" runat="server" OnClick="btnFormat_Click" />
</asp:Content>

C# Code:

protected void btnFormat_Click(object sender, EventArgs e)
{
    string formattedString = "";
    foreach (char c in this.txtOriginalString.Text.ToCharArray())
        formattedString += c + "-";
    this.txtFormattedString.Text = formattedString;
}

Answer 6

Is this what you wanted?

var r = new Regex( @"([A-Za-z0-9])(?!$|\s)" );
var text = "Thisisatest";
var text2=r.Replace( text,"$1-" );

Another version:

    string AddHyphens(string s)
    {
        string ret="";
        foreach(char c in s.ToCharArray())
            ret += ret != "" ? "-" + c : c.ToString();
        return ret;
    }

Answer 8

string str = "sometext";
string output="";
if(str.Length>0)
{
    output=""+str.ElementAt(0);

    for(int i =1; i< str.Length;i++)
        output += "-"+str.ElementAt(i); 
}
