C# linq转datatable

以下是将一个List转换为DataTable的C# Linq代码示例：

List<Person> personList = new List<Person>()
{
    new Person() { Id = 1, Name = "Alice", Age = 20 },
    new Person() { Id = 2, Name = "Bob", Age = 25 },
    new Person() { Id = 3, Name = "Charlie", Age = 30 }
};

DataTable dataTable = new DataTable();
dataTable.Columns.Add("Id", typeof(int));
dataTable.Columns.Add("Name", typeof(string));
dataTable.Columns.Add("Age", typeof(int));

personList.ForEach(person => dataTable.Rows.Add(person.Id, person.Name, person.Age));

其中，Person是一个自定义的类，用于存储每个人的信息，如下所示：

public class Person
{
    public int Id { get; set; }
    public string Name { get; set; }
    public int Age { get; set; }
}
