C# 7.表格 dataGridView

工具箱使用dataGridView(表格)

右键属性 找到Columns(集合)

添加 页眉文本更改名称；类型可以设置表格类型

代码：

设置不可编辑

dataGridView1.ReadOnly = true;

取消自动创建列

dataGridView1.AllowUserToAddRows = false;

添加数据

创建

List<Student> list = new List<Student>();

  public Form1(){
List<Student> list = new List<Student>();list = new List<Student>();for (int i = 0; i < 10; i++){list.Add(new Student(){Name = "女朋友" + i + "号",Age = i * 10,Sex = i % 2 == 0 ? "男" : "女",Job = "开挖掘机",});}dataGridView1.DataSource = ToDataTable(list);
}

作业表格展示学生三门成绩 最后展示总成绩

类添加三个科目

方法1：

for (int i = 0; i < 10; i++)
{
    Student s1 = new Student();
    s1.Name = "女朋友" + i + "号";
      s1.Age = i * 10;
         s1.Sex = i % 2 == 0 ? "男" : "女";
         s1.Job = "开挖掘机";
         s1.tiyu = i * 2;
         s1.sql = i * 3;
        s1.cshap = i * 4;
         s1.sum = s1.tiyu+s1.sql+s1.cshap;
    list.Add(s1);
    dataGridView1.DataSource = ToDataTable(list);
}
 

方法2：

 for (int i = 0; i < 10; i++)
 {
     list.Add(new Student()
     {
         Name = "女朋友" + i + "号",
         Age = i * 10,
         Sex = i % 2 == 0 ? "男" : "女",
         Job = "开挖掘机",
         tiyu = i * 2,
         sql = i * 3,
         cshap = i * 4,
         sum = i * 2 + i * 3 + i * 4
     });

dataGridView1.DataSource = ToDataTable(list);
 }

只有添加累的循环
