【问题描述】：

如何从我的 access 数据库 "contacts.accdb" 填充组合框中组合 "Firstname" "Lastname" 列？我已经将dataset +datagridview 加载到项目中的另一个表单中..

【参考方案1】：

一个简单但完整的例子：

Dim con as New OledbConnection = connectionstringhere
Dim cmd as New OleDbCommand("Select * from tablenamehere",con)
Dim dr as OledbDataReader=cmd.ExecuteReader
While dr.read
Dim FnameAndLname as string = dr(0).ToString + " " + dr(1).ToString 'Assuming the FirstName is the 1st and the LastName is the 2nd Column of the table
MyConboBox.Items.Add(FnameAndLname)
End while

希望这会有所帮助:)

【讨论】：

我想您可能想在名字和姓氏之间添加 & " " &。

@Mary，是的，添加了它，以防 OP 想要一个 SPACE

Dim cn As New OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=|DataDirectory|\Contactos.accdb;Persist Security Info=False;") cn.Open() Dim cm As New OleDbCommand("select * from ContactosTabla", cn) Dim dr As OleDbDataReader = cm.ExecuteReader While dr.Read ComboBox3.Items.Add(dr(1).ToString + " " + dr(2).ToString) 'Assuming the FirstName is the 1st and the LastName is the 2nd Column of the table End While dr.Close() cn.Close()
