栗克2024-07-31 9:02

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>();

cs 复制代码

  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
