// Create the insert command.
String insertSql = "INSERT INTO [Sheet1$] " +
"(CategoryID, CategoryName, Description) " +

Intento llenar una hoja Excel 97 desde una aplicación de Visula Studio
2003
en C#, y siempre me aparece el mismo error, aunque he probado diferentes
métodos.

Alguien lo ha hecho y le ha funcionado.?

Gracias de antemano.
