读取Excel文件内容到DataSet

读取Excel文件内容到DataSet

用途：快速读取Excel数据

特点：使用内部引擎读，不需安装Excel，读取不会启动Excel的进程

 

            DataSet ds = null;
                string strConn = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source= " + fileName + ";Extended Properties='Excel "
                    + (fileName.EndsWith("xls", StringComparison.CurrentCultureIgnoreCase) ? "8" : "12") + ".0;HDR=" + (isFirstTitle ? "Yes" : "No") + "'";
                using (OleDbConnection conn = new OleDbConnection(strConn))
                {
                    conn.Open();
                    //返回Excel的架构，包括各个sheet表的名称,类型，创建时间和修改时间等 
                    DataTable dtSheetName = conn.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, new object[] { null, null, null, "Table" });
                    ds = new DataSet();
                    //包含excel中表名的字符串数组
                    for (int k = 0; k < dtSheetName.Rows.Count; k++)
                    {
                        string strTableName = dtSheetName.Rows[k]["TABLE_NAME"].ToString();
                        string str = "select * from [" + strTableName + "]";
                        OleDbDataAdapter da = new OleDbDataAdapter(str, conn);
                        da.Fill(ds, strTableName.Replace("$", "").ToLower());
                        da.Dispose();
                    }
                   conn.Close();
                    conn.Dispose();
                }
