Vb.net 将Excel数据导入Access数据库

我想像这样将数据从Excel导入Access，当我的Access数据库没有密码时它工作，但当它有密码时它不工作。 我从网上复制了这个代码

我必须将访问密码放在哪里

Dim Access As String = "C:\FWS\Database1.accdb"
Dim Excel As String = "C:\New folder\2h.xlsx"
' Dim connect As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & Excel & ";Extended Properties=Excel 8.0;"

Dim connect As String = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + Excel + ";Extended Properties=""Excel 12.0 Xml;HRD=NO"""


    Using conn As New OleDbConnection(connect)
        Using cmd As New OleDbCommand()
            cmd.Connection = conn
            cmd.CommandText = "INSERT INTO [MS Access;Database=" & Access & "].[Password=frozbit].[tb_voucher2] SELECT * FROM [2hari$]"
            If conn.State = ConnectionState.Open Then
                conn.Close()
            End If
            conn.Open()
            cmd.ExecuteNonQuery()
        End Using
    End Using

通过快速搜索：

或

注意：这些未经测试。

将

cmd.commandText

更改为：

cmd.CommandText = "INSERT INTO [MS Access;Database=" & Access & ";
    PWD=frozbit].[tb_voucher2] SELECT * FROM [2hari$]"

请像使用我的密码一样使用您的db密码。我的密码是123

    Using cmd As New OleDbCommand()
    cmd.Connection = conn
    cmd.CommandText = "INSERT INTO [MS Access;Database=" & Access & ";PWD=**123**].[Sheet1] SELECT * FROM [Sheet1$]"
    If conn.State = ConnectionState.Open Then
       conn.Close()
    End If
    conn.Open()
    cmd.ExecuteNonQuery()
    MessageBox.Show("succussfully updated")
    Form4.Show()
    Me.Hide()

Taka mala sugestia“C:\FWS\Database1.accdb，False，False”，MS访问；PWD=密码“）

"Provider=Microsoft.Jet.OLEDB.4.0; Data Source=c:\App1\Your_Database_Name.mdb; User Id=admin; Password="

cmd.CommandText = "INSERT INTO [MS Access;Database=" & Access & ";
    PWD=frozbit].[tb_voucher2] SELECT * FROM [2hari$]"

    Using cmd As New OleDbCommand()
    cmd.Connection = conn
    cmd.CommandText = "INSERT INTO [MS Access;Database=" & Access & ";PWD=**123**].[Sheet1] SELECT * FROM [Sheet1$]"
    If conn.State = ConnectionState.Open Then
       conn.Close()
    End If
    conn.Open()
    cmd.ExecuteNonQuery()
    MessageBox.Show("succussfully updated")
    Form4.Show()
    Me.Hide()
