请教：DropDownList控件问题

Question

DropDownList1.SelectedIndex=DropDownList1.Items.IndexOf(new ListItem(text值,value值));

Answer 1

如果text和value不一样
DropDownList1.SelectedIndex=DropDownList1.Items.IndexOf(DropDownList1.Items.FindByText("abc"));
或
DropDownList1.SelectedIndex=DropDownList1.Items.IndexOf(DropDownList1.Items.FindByValue("abc"));

Answer 2

还是报同样的错。
即使我写成DropDownList1.SelectedIndex=3;
