Question

我面临着从数据库中获取组合框的价值的问题

 `String stri = "Select [Interest] from tbl_Interests";
            SqlCommand command = new SqlCommand(stri, con);
            SqlDataAdapter da = new SqlDataAdapter(command);
            DataSet ds = new DataSet();
            da.Fill(ds,"tbl_Interests");
            cmbTypeofList.DataSource = ds.Tables["tbl_Interests"];
            cmbTypeofList.ValueMember = "Interest";`

打电话给它 string intr = cmbTypeofList.SelectedItem.ToString(); string intr = cmbTypeofList.SelectedValue.ToString(); 在上述两种情况下，我将所选值作为System.Data.DataRowView

string intr = cmbTypeofList.SelectedText; 如果我给出上述方式我得到“”空值
