Okuma süresi: 12 dakika

Sizler için C# ile bir çok veri tabanına bağlantı yapabilmeniz için bağlantı cümlelerini bir araya getirdim. Makale içinde bulunan veritabanları şunlardır:

  •  MS SQL Server,
  • MS SQL Express,
  • MS Access, Oracle,
  • IBM DB2,
  • MySql,
  • Sybase,
  • Interbase,
  • Informix,
  • Excel,
  • Text,
  • dBase Dbf,
  • Visual FoxPro .

 

Umarım faydasını görürsünüz.
