windows forms and cmd issue. ( arguments )

good afternoon -

been trying for a while now to get my argements passed to cmd i know it uses only one string arguments so i done a string join

        public void searchartist(string search)  
        {  
            if (search == string.Empty)  
            {  
                XtraMessageBox.Show("Please Provide search term ");  
            }  
            else  
            {  
                System.Diagnostics.Process p = new System.Diagnostics.Process();  
                p.StartInfo.UseShellExecute = false;  
                p.StartInfo.FileName = "cmd.exe";  
                string[] myargs = { "/c spotdl download ", "'", search, "'" };  
                string elfen = string.Join("", myargs);  
                XtraMessageBox.Show(elfen);  
                p.StartInfo.Arguments = string.Join("",elfen);  
                p.StartInfo.RedirectStandardError = true;  
                p.StartInfo.RedirectStandardInput = true;  
                p.StartInfo.RedirectStandardOutput = true;  
                p.StartInfo.CreateNoWindow = true;  
  
                p.Start();  
  
                StreamReader outputWriter = p.StandardOutput;  
                //String errorReader = p.StandardError.ReadToEnd();  
                String line = outputWriter.ReadLine();  
                while (line != null)  
                {  
                    XtraMessageBox.Show(line);  
                }  
                p.WaitForExit();  
            }  
        }  

the string join shows,

however this is not working well its just showing in the line

Searching Spotify for song named "download"...

but have no idea why its doing this when the arg passed is one string

any help would be much appreiated
