[ASP.net教程]c#通过oledb获取excel文件表结构信息


这个问题来自论坛提问,同理可以获得access等数据库的表结构信息。

using System; namespace ConsoleApplication11 {   class Program   {     public  static  void Main()     {       getExcelFileInfo( @" c:a.xls " );     }      private  static  void getExcelFileInfo( string Path)     {       string strConn =  " Provider=Microsoft.Jet.OLEDB.4.0; "  +  " Data Source= "  + Path +  " ; "  +  " Extended Properties=Excel 8.0; " ;       System.Data.OleDb.OleDbConnection conn =  new System.Data.OleDb.OleDbConnection(strConn);       conn.Open();       System.Data.DataTable table = conn.GetOleDbSchemaTable(System.Data.OleDb.OleDbSchemaGuid.Tables, null );        foreach (System.Data.DataRow drow in table.Rows)       {         string TableName = drow[ " Table_Name " ].ToString();         Console.WriteLine(TableName + " : " );         System.Data.DataTable tableColumns = conn.GetOleDbSchemaTable(System.Data.OleDb.OleDbSchemaGuid.Columns, new  object [] { null , null , TableName , null } );         foreach (System.Data.DataRow drowColumns in tableColumns.Rows)         {           string ColumnName = drowColumns[ " Column_Name " ].ToString();           Console.WriteLine( " " + ColumnName);         }       }       Console.ReadKey( true );     }   } } /* 何问起 hovertree.com */
