学习记录

   今天在家里学习了C#基础知识，为了不使自己忘记，方便以后复习，特作一些笔记记录。

 我做的内容如下图：

代码是：

 private void btncalulate_Click(object sender, EventArgs e)
        {
            int sum = 0;
            Dictionary<string, int> dic = new Dictionary<string, int>();
            string s = txtscore.Text;
            string[] na = s.Split('|');
            foreach( var im in na)
            {
                Console.WriteLine(im);
            }
            for (int i = 0; i < na.Length ; i++)
            {
                //MessageBox.Show(na[i]);
                string[] nab = na[i].Split('=');
                dic.Add(nab[0], int.Parse(nab[1]));
            }
            foreach (var item in dic)
            {
                sum = sum + item.Value;
               // MessageBox.Show(sum.ToString());
            }
            txtscore.Text ="总和是："+ sum.ToString();
            label3.Text = "总和是：" + sum.ToString();
            Console.WriteLine(dic.Count.ToString()+"dsskkkk");

        }

        private void btntwo_Click(object sender, EventArgs e)
        {
            btncalulate_Click( sender,e);
            string[] na = txttwo.Lines;
            Dictionary<string, int> dic = new Dictionary<string, int>();
            for (int i = 0; i < na.Length; i++)
            {
               // MessageBox.Show(na[i]);
                string[] nab = na[i].Split('=');
                dic.Add(nab[0], int.Parse(nab[1]));
            }
            int max = -1;
            string name = "";
            /*foreach(string l in na)
            {
                string [] naa = l.Split('=');
                string named = naa[0];
                int score =Convert.ToInt32( naa[1].ToString());
                if(score>max)
                {
                    max = score;
                    name = named;
                }
            }*/
            foreach( var item in dic)
            {
                if (item.Value > max)
                {
                    max = item.Value;
                    name = item.Key;
                }
               // MessageBox.Show(item.Key+" adddd "+item.Value);
            }
            label4.Text="最高的是"+name+",数值是："+max.ToString();
            MessageBox.Show("最高的是"+name+",数值是："+max.ToString()+"");

           /* for (int index = 0; index < dic.Count; index++)
            {
                KeyValuePair<string, int> item = dic.ElementAt(index);
              //  item.GetType();
               // var item = dic.ElementAt(index);
                //var itemKey = item.Key;
               // var itemValue = item.Value;
                string itemKey = item.Key;
                 int itemValue = item.Value;
                MessageBox.Show("他是" + itemKey + ",数值是：" + itemValue.ToString() + "");
            }*/
        }

运行后的结果是

做这个记录，是为了理解一些方法的使用，一些知识点的灵活运用。
