var arr = [ "C", "c", "b", "B", "A" ]; 
 
var text =""; 
 
arr.forEach(function(val,index){ 
 
    if(index <= arr.length-2){ 
 
    text = text + val +","

Answer 2

請檢查下面

char [] data = { 'C', 'c', 'b', 'B', 'A' }; 
string joinString = string.Join(", ", data); 

string result = string.Format("your character is {0}", joinString.Insert(joinString.LastIndexOf(",")+1, " and"));
