c# - 在ASP.NET中发布GridView

我只想知道最后两行之间的区别

protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
 if (GridView1.Rows[e.RowIndex].RowType == DataControlRowType.DataRow)
  {
   GridViewRow row = (GridViewRow)GridView1.Rows[e.RowIndex];

   string lstnme = ((TextBox)row.Cells[2].FindControl("txtLstNme")).Text;

和

   string lstnme=((TextBox)row.Cells[2].Controls[0]).Text;
}

最佳答案

没有区别，但我建议您在分配Text值之前检查控件是否为null

string lstnme = string.Empty;
var control = ((TextBox)row.Cells[2].FindControl("txtLstNme"));
if ( control != null )
{
     lstnme = control.Text
}
