//如果DropDownList1的Text和Value值一致
this.DropDownList1.SelectedIndex= this.DropDownList1.Items.IndexOf(new ListItem(指定项));
//如果Text和Value值不一致
this.DropDownList1.SelectedIndex= this.DropDownList1.Items.IndexOf(this.DropDownList1.Items.FindByText(指定项));//指定Text值
this.DropDownList1.SelectedIndex= this.DropDownList1.Items.IndexOf(this.DropDownList1.Items.FindByValue(指定项));//指定Value值
