c#通過oledb獲取excel文件表結構信息

這個問題來自論壇提問，同理可以獲得access等資料庫的表結構信息。

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 );
         } 
     }
