Excel的OleDb处理

一、获取所有sheet

 

 try

            {

                string strFileName = "d:\\Book1.xls";

                string strConn = "Provider=Microsoft.Jet.OLEDB.4.0;" +  "Data Source=" + strFileName + ";" +   "Extended Properties=Excel 8.0;";

                OleDbConnection conn = new OleDbConnection(strConn);

                conn.Open();

                DataTable schemaTable = conn.GetOleDbSchemaTable(System.Data.OleDb.OleDbSchemaGuid.Tables, null);

                foreach (DataRow row in schemaTable.Rows)

                {

                    for (int i = 0; i < schemaTable.Columns.Count; i++)   {

                        Response.Write(row[i].ToString() + "    ");

                    }

                    Response.Write("<br/>");

                }

                conn.Close();

            }

            catch (Exception ex)

            { 

            }
