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:)
