如果您读取查询字符串，则可以对从那里提取的数据进行任何操作.

If you read the query string, you can do whatever you like with the data you pull from there.

protected void Page_Load(object sender, EventArgs e)
{
dropDownList1.SelectedValue = Request.QueryString[querystring];
}

前提是将DropDownList的值"字段属性设置为您通过查询字符串传递的状态的值.

This is provided that the Value field property of the DropDownList is set to values of the status(s) you are passing thru the querystring.
