C#如何实现dataGridView动态绑定数据

DataGridView dgv = new DataGridView();
DataTable dt = new DataTable();//DataGridView未设置列名信息的时候可以直接指定DataSource
dt.Columns.Add("姓名", Type.GetType("System.String"));
dt.Columns.Add("性别", Type.GetType("System.String"));
dt.Columns.Add("年龄", Type.GetType("System.Int16"));
//====================添加行数据方法1============================
//dt.Rows.Add(new object[]{"张三","男",22});
//dt.Rows.Add(new object[]{"李四","女",20});
//====================添加行数据方法1============================
//====================添加行数据方法2============================
DataRow dr = dt.NewRow();
dr[0] = "张三";
dr[1] = "男";
dr[2] = 22;
dt.Rows.Add(dr); 
DataRow dr2 = dt.NewRow();
dr2[0] = "李四";
dr2[1] = "女";
dr2[2] = 20;
dt.Rows.Add(dr2);                                      
//====================添加行数据方法2============================ 
                 
dgv.DataSource = dt;

//DataGridView已经在可视化界面设置好列名后不能再指定DataSource(指定了显示会走样)
string[] names = { "张三", "李四" };
string[] sexs = { "男", "女" };
int[] ages = { 22, 20 };
for (int i = 0; i < names.Length; i++)
{
    dgv.Rows.Add();
    dgv.Rows[i].Cells[0].Value = names[i];
    dgv.Rows[i].Cells[1].Value = sexs[i];
    dgv.Rows[i].Cells[2].Value = ages[i];
}  
//====================添加单行可使用============================ 
 //DataGridViewRow dgr = new DataGridViewRow();
//int index = dgv.Rows.Add(dgr);
 //dgv.Rows.Add();
//dgv.Rows[index].Cells[0].Value = names[0];
 //dgv.Rows[index].Cells[1].Value = sexs[0];
//dgv.Rows[index].Cells[2].Value = ages[0];
//====================添加单行可使用============================
