Combobox ValueMember

Question

我使用此代码填充组合框但是可能在第2列ex1上的column1 ex：name处关联; ID？使用cmbbox.valuemember =

private DataTable BindData() 
        { 
            using (var conn = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0; Data Source=C:\YOURDB.mdb; PersSecurity Info=False;")) /your connectionsting 
            { 
                using (var dAd = new OleDbDataAdapter("select column1 from Table ", conn)) //select query from your DB 
                { 

                    var dSet = new DataTable(); 
                    try 
                    { 
                        conn.Open(); 

                        dAd.Fill(dSet); 

                        return dSet; 

                    } 
                    catch 
                    { 
                        throw; 
                    } 
                    finally 
                    { 
                        if (conn.State == ConnectionState.Open) conn.Close(); 
                    } 
                } 
            } 
        }

var dt = BindData(); 
        cmbBox.DataSource = dt; 
        cmbBox.DisplayMember = "column1"; //Display Table Column on your DB
