Question

gridview 某列值如何循环全部输出

Answer 1

for (int i = 0; i < GridView1.Rows.Count; i++)//遍历行
{

//string value = GridView1.Rows[i].Cells[0].Text //0为首列，以此类推
}

Answer 2

for (int i = 0; i < this.GVUserInfo.Rows.Count; i++)//GVUserInfo是你的GirdView，lblId是你该行要取的控件
{
int id = int.Parse((GVUserInfo.Rows[i].FindControl("lblId") as Label).Text);
}
