由鍵盤輸入資料 • Console. Read(); • Console. Read. Line(); 13

範例1：輸入與輸出 任務）請使用者輸入姓名與年齡。 static void Main(string[] args) { string Your. Name; int age; Console. Write("請輸入你的名字："); Your. Name = Console. Read. Line(); Console. Write. Line("Hello, {0}", Your. Name); Console. Write("請輸入你的年齡："); age = Int. Parse(Console. Read. Line()); Console. Write. Line("{0}您好！您是{1}歲", Your. Name, age); Console. Read. Line(); } 29

範例2：檔案讀取 任務）讓使用者輸入一個成績，判斷是否及格。 using System. IO; File. Info file = new File. Info("c: \grade. txt"); Stream. Reader sr = file. Open. Text(); int score 1, score 2, score 3; double average; score 1 = int. Parse(sr. Read. Line()); score 2 = int. Parse(sr. Read. Line()); score 3 = int. Parse(sr. Read. Line()); average = (score 1 + score 2 + score 3) / 3. 0; Console. Write. Line("平均是{0: f}分", average); Console. Read(); sr. Close(); 30

範例4：重複結構 任務）讀入檔案的10個分數。使用for語法。 using System. IO; File. Info file = new File. Info("c: \grade. txt"); Stream. Reader sr = file. Open. Text(); for (int i=1; i<=10; i++) { 　Console. Write. Line(sr. Read. Line()); } Console. Read(); sr. Close(); 32

範例5：重複結構 任務）讀入檔案的不定個數的分數。使用while語法。 using System. IO; File. Info file = new File. Info("c: \grade. txt"); Stream. Reader sr = file. Open. Text(); while (sr. Peek() > 0) 　Console. Write. Line(sr. Read. Line()); } Console. Read(); sr. Close(); 33

範例6：陣列 任務）讀入檔案中的10個分數。 using System. IO; File. Info file = new File. Info("c: \grade. txt"); Stream. Reader sr = file. Open. Text(); int[ ] score = new int[10]; for (int i=0; i<10; i++) { 　score[i]= int. Parse(sr. Read. Line()); } Console. Read(); sr. Close(); 34

範例7：陣列 任務）讀入檔案中的不定個數的分數。 using System. IO; File. Info file = new File. Info("c: \macdonald. txt"); Stream. Reader sr = file. Open. Text(); Array. List score = new Array. List(); while (sr. Peek() > 0) { score. Add(sr. Read. Line()); } 35
