--------------------------------2007及以上的版本--------------------------------
测试如下：
1 //DataInterface.Method 2 /// <summary> 3 /// 读取2007版本excel 4 /// </summary> 5 /// <param name="filePath">文件路径</param> 6 /// <returns>返回一个表</returns> 7 public System.Data.DataTable GetExcel2007(string filePath) 8 { 9 try 10 { 11 string strConn = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + filePath + ";Extended Properties="Excel 12.0;HDR=NO;IMEX =1""; 12 13 OleDbConnection conn = new OleDbConnection(strConn); 14 conn.Open(); 15 System.Data.DataTable schemaTable = conn.GetOleDbSchemaTable(System.Data.OleDb.OleDbSchemaGuid.Tables, null); 16 //获取Excel文件中第一个（按字母排序的）sheet页的页名。 17 string tableName = schemaTable.Rows[0][2].ToString().Trim(); 18 19 string strExcel = "SELECT * FROM [" + tableName + "]"; 20 OleDbDataAdapter myCommand = null; 21 myCommand = new OleDbDataAdapter(strExcel, strConn); 22 DataSet ds = new DataSet(); 23 myCommand.Fill(ds, "dtSource"); 24 System.Data.DataTable table = ds.Tables["dtSource"]; 25 conn.Close(); 26 return table; 27 } 28 catch 29 { 30 return null; 31 } 32 }
--------------------------------2007以下的版本--------------------------------
测试如下：
1 /// <summary> 2 /// 读取2003版本excel 3 /// </summary> 4 /// <param name="filePath"></param> 5 /// <returns></returns> 6 public System.Data.DataTable GetExcel2003(string filePath) 7 { 8 //读取OMR结果文件(xls)数据 9 try 10 { 11 //由于windows系统的更新，无法正常使用此strConn 12 //如果继续想用请对系统更新的补丁卸载即可 13 //string strConn = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + xlsPath + 14 15 ";Extended Properties="Excel 8.0;HDR=YES;IMEX=1""; 16 //也可以使用以下strConn 17 string strConn = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + filePath + 18 19 ";Extended Properties="Excel 8.0;HDR=NO;IMEX=1""; 20 OleDbConnection conn = new OleDbConnection(strConn); 21 conn.Open(); 22 System.Data.DataTable schemaTable = conn.GetOleDbSchemaTable 23 24 (System.Data.OleDb.OleDbSchemaGuid.Tables, null); 25 //获取Excel文件中第一个(按字母排序的)sheet页的页名。 26 string tableName = schemaTable.Rows[0][2].ToString().Trim(); 27 28 string strExcel = "SELECT * FROM [" + tableName + "]"; 29 OleDbDataAdapter myCommand = null; 30 myCommand = new OleDbDataAdapter(strExcel, strConn); 31 DataSet ds = new DataSet(); 32 myCommand.Fill(ds, "dtSource"); 33 System.Data.DataTable table = ds.Tables["dtSource"]; 34 conn.Close(); 35 return table; 36 } 37 catch 38 { 39 return null; 40 } 41 }
