Generic List

[shapper]

Hello,

How can I convert a Generic.List(Of String) to a single string where
all elements are separated by a comma?

My string would become:

"item1,item2,it em3"

Thanks,

Miguel

Re: Generic List

C# example

List<stringStrl ist = new List<string>();

StrList.Add("1" );
StrList.Add("2" );
StrList.Add("3" );

string SingleString = "";
foreach(string s in Strlist.ToArray ())
SingleString += s + ",";

You can then either remove the last ","
or in the loop work out which is the first item or last

Re: Generic List

Howdy,

I'd would not recommend this approach as is inefficient (first copy to
array, and then string concatenation). This is much faster:

public static string ConcatList<T>(
System.Collecti ons.Generic.ILi st<Tlist, char separator)
{
System.Text.Str ingBuilder text =
new System.Text.Str ingBuilder();

for (int i = 0; i < list.Count; i++)
{
text.Append(lis t[i]);
text.Append(sep arator);
}

if (text.Length 0)
text.Length -= 1;

return text.ToString() ;
}

Re: Generic List

thanks for a more efficient method.

I'll be sure to use that in future
