C#——DataGridView选中行，在TextBox中显示选中行的内容

C#——DataGridView选中行，在TextBox中显示选中行的内容，在DataGridView的SelectionChanged实践中设置如下代码

private
void
dataGridView1_SelectionChanged(object
sender, EventArgs
e)

{

int
index
=
dataGridView1.SelectedRows[0].Index; //获取选中行的行号

textBox1.Text
=
dataGridView1.Rows[index].Cells[0].Value.ToString();

textBox2.Text
=
dataGridView1.Rows[index].Cells[1].Value.ToString();

 

this.textBox_ID.Text
=
this.dataGridView1.SelectedRows[0].Index.ToString();

this.textBox_CityName.Text=this.dataGridView1.CurrentRow.Cells[1].Value.ToString();//按照这种写法也可以

this.textBox_CityCode.Text
=
this.dataGridView1.CurrentRow.Cells[2].Value.ToString();

this.textBox_District.Text
=
this.dataGridView1.CurrentRow.Cells[3].Value.ToString();

this.textBox_Population.Text
=
this.dataGridView1.CurrentRow.Cells[4].Value.ToString();

}
