private DataTable GetData(string Path, string exceltype)
{
   try
   {
     string strConn = "Provider=Microsoft.Jet.OLEDB.4.0;" + "Data Source=" + Path + ";" + "Extended Properties=Excel 8.0;";

        }
        OleDbConnection conn = new OleDbConnection(strConn);
        conn.Open();
        //得到所有sheet的名称
         DataTable dtSheetName = conn.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, new object[] { null, null, null, "Table" });
        string strExcel = "";
        OleDbDataAdapter myCommand = null;
        strExcel = "select * from [" + dtSheetName.Rows[0]["TABLE_NAME"].ToString() + "]";
         myCommand = new OleDbDataAdapter(strExcel, strConn);
         DataTable dt = new DataTable();
         myCommand.Fill(dt);
         conn.Close();
         return dt;
