Answer 1

You can accelerate a bit by comparing the first character before invoking StartsWith:

char first = prefixText[0];

foreach(string a in ) 
    {    
         if (a[0]==first)
         {        
            if(a.StartsWith(prefixText, true, null)) 
            { 
                newlist.Add(a);                    
            }
         }             
    }
