用vb.net啊

可以使用以下代码将Excel数据导入Access数据库：

'连接Access数据库
Dim conn As New OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\myFolder\myAccessFile.accdb;")
conn.Open()

'读取Excel数据
Dim connExcel As New OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\myFolder\myExcelFile.xlsx;Extended Properties='Excel 12.0 Xml;HDR=YES;'")
Dim cmdExcel As New OleDbCommand("SELECT * FROM [Sheet1$]", connExcel)
Dim daExcel As New OleDbDataAdapter(cmdExcel)
Dim dtExcel As New DataTable()
daExcel.Fill(dtExcel)

'将Excel数据插入Access数据库
For Each row As DataRow In dtExcel.Rows
    Dim cmdAccess As New OleDbCommand("INSERT INTO myTable (field1, field2, field3) VALUES (@field1, @field2, @field3)", conn)
    cmdAccess.Parameters.AddWithValue("@field1", row("Column1"))
    cmdAccess.Parameters.AddWithValue("@field2", row("Column2"))
    cmdAccess.Parameters.AddWithValue("@field3", row("Column3"))
    cmdAccess.ExecuteNonQuery()
Next

'关闭连接
conn.Close()

在上面的代码中，您需要将Access数据库文件路径和Excel文件路径替换为您自己的路径，并将表名和字段名替换为您自己的表名和字段名。
