c# - 如何将数据从 texboxes 插入到 datagridview？

Question

我想做一个电话本，需要把文本框里的联系方式添加到数据 GridView 。

下面是我的代码

它的问题是每次在第一行填满后 - 它不再是新行。

 class information
{
    public string firstname { get; set; }
    public string surname { get; set; }
    public int phonenumber { get; set; }
    public int cellphone { get; set; }
    public string email { get; set; }

}

如何在我的代码中使用这个类？

DataTable dt = new DataTable();
DataRow dr;

dt.Columns.Add("Firstname");
dt.Columns.Add("Lastname");
dt.Columns.Add("PhoneNumber");

dr = dt.NewRow();
dr["Firstname"] = tb1.Text;
dr["Lastname"] = tb2.Text;
dr["PhoneNumber"] = tb3.Text;

dt.Rows.Add(dr);
dataGridView1.DataSource = dt; 

Answer 1

我会这样做:

private void PopulateGridView()
{
    var myRecords = new List<PhoneBookRecord>();
    myRecords.Add(new PhoneBookRecord { FirstName = "blah", LastName = "Blah", PhoneNumber = "1234" });
    myRecords.Add(new PhoneBookRecord { FirstName = "New", LastName = "Song", PhoneNumber = "132134" });
    temper.DataSource = myRecords; 
}

class PhoneBookRecord
{
    public string FirstName { get; set; }
    public string LastName { get; set; }
    public string PhoneNumber { get; set; }
}
