新手代求指一下
Dim connectionstring As String = ".........."
Dim querystring As String = "select * from 申表"
Dim conn As New OleDb.OleDbConnection(connectionstring)
Try
conn.Open()
Dim cmd As New OleDb.OleDbCommand(querystring, conn)
Dim reader As OleDb.OleDbDataReader
Dim dt1 As OleDb.OleDbDataReader
reader = cmd.ExecuteReader()
dt1 = reader

下面我想再接著行第二查然後把二果集合,再DataGridView1,要如何下去
dt1.Merge(reader)'句可以？
DataGridView1.DataSource = dt1

[解决办法]
dt1.Merge()方法需要什么参数，智能提示里有的。
