StringBuilder, add Tab between Values

Question

I have a small problem:

I have a List of fields, with 3 Values. I want to build my String with these three Values, delimited by a "TAB"..

Code:

StringBuilder stringBuilder = new StringBuilder();
foreach (string field in fields)
{
    stringBuilder.Append(field).Append("\t");
}
stringBuilder.AppendLine();
return stringBuilder.ToString();

The Tab is only between the 3rd and 2nd Value (Between 1st and 2nd is a Space ?!)

So I tried this:

StringBuilder stringBuilder = new StringBuilder();
foreach (string field in fields)
{
    stringBuilder.Append(field + "\t").Append("\t");
}
stringBuilder.AppendLine();
return stringBuilder.ToString();

Then I have 2 Tabs between 3rd and 2nd, one Tab between 1st and 2nd and also a Space between 1st and 2nd..

(The Space is always there, how to avoid that?)

So what I have to do? Need only (without spaces..) a Tab between these Values..

How do you verify the tab is not there? By looking at where on the screen the text ends up? – Lesterlesya

At least I'm taking the String (return) and I copy it to Clipboard via Code, then I paste it in the Notepad – Incurve

Are you aware that Notepad sets tab stops at fixed points, and if your tab ends up close to such point, it will appear as narrow as a space? – Lesterlesya

just saw that now.. Tried it then in Word and there it works.. Well Problem solved ;D – Incurve

probably could do with looking in notepad++/vim or something with a binary editor to look at what you actually have – Kickback

should download it first hehe – Incurve

hmm, notepad++ shows the same like notepad, the false things, but Word shows it well... – Incurve

Answer 1

try

StringBuilder stringBuilder = new StringBuilder();
foreach (string field in fields)
{
    stringBuilder.Append(field.Trim()).Append("\t");
}
stringBuilder.AppendLine();
return stringBuilder.ToString();

Basically I would just use return string.Join ( "\t", fields ); .

just solved the problem, look at Question Comment, but the Idea with Trim is good, I'l mark that as answer :) – Incurve

Is this platform independent ? for example, Environment.Newline is platform independent while "\n" is not. – Quartzite

@blasto AFAIK there is only one character for "Tab" - so IMHO this is platform-independent... – Fugal

Answer 2

I think you are confusing with tab char and sapces.

Are you expecting fixed no of white spaces to be added in the end of every word?

\t -> is just a tab char

The following is generated by the code given by you.

Java    StackOverflow   Banyan
Javasun StackOverflow   Banyan

The above two lines have same tab char b/w the 1st & 2nd Word.

if you type one more char in the end of "Javasun" it will extend like the following

Answer 3

I would have thought you would want

StringBuilder stringBuilder = new StringBuilder();
foreach (string field in fields)
{
    stringBuilder.Append(field);
    stringBuilder.Append("\t");
}
stringBuilder.AppendLine();
return stringBuilder.ToString();

Kickback

although looking at MSDN, Append returns a reference to the stringbuilder anyway so shouldn't make a difference. – Kickback

it's the same.. but just solved the problem, look at Question Comment – Incurve

yep, I added a comment up there too – Kickback

Answer 4

Instead of looping, you can use string.Join:

StringBuilder stringBuilder = new StringBuilder();

stringBuilder.AppendLine(string.Join("\t", fields));

Note that you can pass in the string directly to AppendLine as well.

Sub WarningWindow(ByVal content As String)
    Dim sw As New StringWriter()
    Dim hw As New HtmlTextWriter(sw)
    Dim gridHTML As String = sw.ToString().Replace("""", "'").Replace(System.Environment.NewLine, "")
    Dim sb As New StringBuilder()
    Dim a As String = "Welcomeback"

call it like WarningWindow("write any thing") – Glasshouse
