推荐答案

if (DropDownList1.SelectedIndex == 1)
    GridView1.DataSourceID = "SqlDataSource2";
else
    GridView1.DataSourceID = "SqlDataSource1";
GridView1.DataBind();



或者使用三元运算符


Or use the ternary operator thus

GridView1.DataSourceID = DropDownList1.SelectedIndex == 1 ? "SqlDataSource2" : "SqlDataSource1";
GridView1.DataBind();
