如何用C#设计学生成绩统计器

1、双击软件，启动Visual Studio 2017

3、打开工具箱，将对应的控件一一的拖放到Form窗体上，摆放好对应位置，修改其Text属性

5、在事件中输入如下代码： static int n = 0; static float[] ascoresum = new float[100]; private void button1_Click(object sender, EventArgs e) { ascoresum[n] = Convert.ToSingle(textBox1.Text); n = n + 1; textBox1.Text = ""; textBox1.Focus(); }

7、在事件中输入如下代码： float bscoresum = 0; for (int i = 0; i <= ascoresum.Length - 1; i++) { bscoresum = ascoresum[i] + bscoresum; } float avescore = bscoresum / n; textBox2.Text = Convert.ToString(avescore); int m = 0; for (int i = 0; i <= ascoresum.Length - 1; i++) { if (ascoresum[i] > avescore) m = m + 1; } textBox3.Text = Convert.ToString(m);
