Assign different values ​to a string using a for

I have the following structure for

for (int i = 0; i < lstArquivosRetorno.Items.Count; i++)
{
    lstArquivosRetorno.SetSelected(i, true);

    string nomeArquivo = string.Format(
      "{0}{1}", 
       Funcoes.IncludeBackSlash(edtPathArquivo.Text),
       lstArquivosRetorno.SelectedItem.ToString());

    _relacaoArquivos.Add(nomeArquivo);
}

What I’m doing is the following: I have a List<string> _relacaoArquivos and I add the filename to that list using that structure, however, if I have more than one file selected, it only stores and adds the first file.

How can I go through my for structure to store and add the names of all files to the list?

>Solution :

lstArquivosRetorno looks like a select list or similar. When creating the nomeArquivo string, the SelectedItem is being used to create the string. That is why you’re getting only one item added to the _relacaoArquivos list.

lstArquivosRetorno.SelectedItem should be lstArquivosRetorno.Items[i]

string nomeArquivo = string.Format(
      "{0}{1}", 
       Funcoes.IncludeBackSlash(edtPathArquivo.Text),
       lstArquivosRetorno.Items[i]); // no need to call ToString()
