c#datagridview数据绑定list

以下是C#中使用DataGridView控件绑定List的示例代码：

1. 首先定义一个数据类Class1，包含两个属性Name和Age：

public class Class1
{
    public string Name { get; set; }
    public int Age { get; set; }

    public Class1(string name, int age)
    {
        Name = name;
        Age = age;
    }
}

2. 在Form中定义一个List<Class1>类型的变量list，并在构造函数中初始化：

public partial class Form1 : Form
{
    private List<Class1> list;

    public Form1()
    {
        InitializeComponent();
        list = new List<Class1>();
    }
}

3. 在DataGridView控件的DataBindingComplete事件中绑定数据源：

private void dataGridView1_DataBindingComplete(object sender, DataGridViewBindingCompleteEventArgs e)
{
    dataGridView1.Columns["Name"].HeaderText = "姓名";
    dataGridView1.Columns["Age"].HeaderText = "年龄";
}

private void button1_Click(object sender, EventArgs e)
{
    list.Add(new Class1("张三", 18));
    list.Add(new Class1("李四", 20));
    dataGridView1.DataSource = list;
}

4. 在DataGridView控件的CellEndEdit事件中更新数据源：

private void dataGridView1_CellEndEdit(object sender, DataGridViewCellEventArgs e)
{
    int rowIndex = e.RowIndex;
    DataGridViewRow row = dataGridView1.Rows[rowIndex];
    string name = row.Cells["Name"].Value.ToString();
    int age = int.Parse(row.Cells["Age"].Value.ToString());
    list[rowIndex].Name = name;
    list[rowIndex].Age = age;
}
