Question

List<String> lstHeaders = new List<string>(new String[]{"str","str1","str2"}); 

I a want a way to join all that elemenet with an specific format to get something like this

<td>str</td><td>str1</td><td>str2</td>

but get this just in online of code , something like this

"<th>"+lstHeaders.functionToGetFormated()+"</th>"

Answer 1

Using Linq and String.Concat:

string result = string.Concat(lstHeaders.Select(s => string.Format("<td>{0}</td>", s)));

Perhaps clearer with query syntax:

string result = string.Concat(from s in lstHeaders select string.Format("<td>{0}</td>", s));
