VB.NET将EXCEL中的数据导入到SQL SERVER

'获取sheet名，其中(0)(1)...(N): 按名称排列的表单元素

Dim tableName As String = dataTable.Rows(0)(2).ToString().Trim()

tableName = "[" & tableName.Replace(" ' "," ") & "]"

'利用SQL语句从Excel文件里获取数据

Dim query As String = "SELECT c1,c2,c3 FROM " & tableName

Dim dataset As DataSet = New DataSet()

Dim oleAdapter As OleDbDataAdapter = New OleDbDataAdapter(query,sConnectionString)

oleAdapter.Fill(dataset,"Rwb")

'可读取EXCEL中的记录数

MessageBox.Show(dataset.Tables(0).Rows.Count)

'SQL数据库连接

Dim sqlcon As SqlClient.SqlConnection = New SqlClient.SqlConnection("Data Source=./sqlexpress;Initial Catalog=test;User ID=sa;Password=123")

sqlDA1.Fill(dataTable1)

Dim dataRow11 As DataRow

For Each dataRow11 In dataset.Tables("Rwb").Rows

'sql里数据dataRow1
