C# 组合框值成员

我使用此代码填充组合框，但可以在第2列的第1列ex:name处关联；身份证件使用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(); 
                    } 
                } 
            } 
        } 

纽扣

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

关于Combobox的DisplayMember和ValueMember属性，这可能会有帮助：
