求一个将excel导入到access数据库的代码！！！谢谢了
刚才已经请教到先导入到dataset中，并通过gridview显示出来，现在想写到access里面，请问怎么写代码。已经读到dataset中的代码是这样的：
protected DataSet DSBind(string filePath)
{
String ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;" + "Data Source=" + filePath + ";" + "Extended Properties=Excel 8.0;";
//Create connection object by using the preceding connection string.
OleDbConnection objConn = new OleDbConnection(ConnectionString);
objConn.Open();
OleDbCommand objCmdSelect = new OleDbCommand("SELECT * FROM [Sheet1$]", objConn);
OleDbDataAdapter objAdapter1 = new OleDbDataAdapter();
objAdapter1.SelectCommand = objCmdSelect;
DataSet objds = new DataSet();
objAdapter1.Fill(objds, "ExcelDataSet");
return objds;
objConn.Close();
}
protected void btnInputData_Click(object sender, EventArgs e)
{
gvData.DataSource = DSBind(fuFile.PostedFile.FileName);
gvData.DataBind();
请问怎么导入到数据库？（还有如果excel有几个sheet，请问怎么解决） --------------------编程问答-------------------- access 讀到 dataset里，
軟后oledbDataApdater。update --------------------编程问答-------------------- OleDbConnection conn = new OleDbConnection(@"Provider=Microsoft.Jet.OleDb.4.0;Data Source=|DataDirectory|\\studentinfo.mdb");
conn.Open();
for (int i = 0; i <= myDataSet.Tables["Excel_Sheet1"].Rows.Count - 1; i++)
{
//...
string intostr = "insert into " + tabel_name + " ([enrollment_date],[name],[sex],[study_mark],[Private_mark],[class])values('" + myDataSet.Tables["Excel_Sheet1"].Rows[i][0].ToString() + "','"
+ myDataSet.Tables["Excel_Sheet1"].Rows[i][1].ToString() + "','" + myDataSet.Tables["Excel_Sheet1"].Rows[i][2].ToString() + "','"

OleDbDataAdapter da = new OleDbDataAdapter(intostr, conn);
OleDbCommandBuilder cmd = new OleDbCommandBuilder(da);
DataSet ds = new DataSet();
da.Fill(ds, tabel_name);
} --------------------编程问答--------------------
这个代码看的不是很明白，能不能贴个完整的 --------------------编程问答-------------------- 顶一下~~~~~~ --------------------编程问答--------------------
这个跟你的那个结合起来用就可以了呀
已经完整了的 --------------------编程问答--------------------
请问如何整合啊，那个if代码是不是要放入click事件里，还有myDataSet.Tables["myDataSet.Tables["Excel_Sheet1"]"]里，Excel_Sheet1要用excel的实际表名？
我把它的if语句改成自己的，6个字段名我都建成他那6个：
for (int i = 0; i <=objds.Tables["Excel_Sheet1"].Rows.Count - 1; i++)
{
//...
string intostr = "insert into tb_excelData ([enrollment_date],[name],[sex],[study_mark],[Private_mark],[class])values('" + objds.Tables["Excel_Sheet1"].Rows[i][0].ToString() + "','"
+ objds.Tables["Excel_Sheet1"].Rows[i][1].ToString() + "','" + objds.Tables["Excel_Sheet1"].Rows[i][2].ToString() + "','"
+ objds.Tables["Excel_Sheet1"].Rows[i][3].ToString() + "','" + objds.Tables["Excel_Sheet1"].Rows[i][4].ToString() + "','" + objds.Tables["Excel_Sheet1"].Rows[i][5].ToString() + "')";
OleDbConnection conn = new OleDbConnection(@"Provider=Microsoft.Jet.OleDb.4.0;Data Source=|DataDirectory|\\info.mdb");
OleDbDataAdapter da = new OleDbDataAdapter(intostr, conn);
OleDbCommandBuilder cmd = new OleDbCommandBuilder(da);
DataSet ds = new DataSet();
da.Fill(ds, "tb_excelData");
