In old projects I am using the OpenLink.Data.Virtuoso provider to access data stored in a Virtuoso server. I now want to upgrade these projects to .NET 8.0 - but I cannot find any update to the provider I used before (it's from 2015).
How can I access (read/write) data to a Virtuoso server with .NET 8.0?
Thanks in advance,
Frank
I searched the web but all I found was the old provider for ADO.NET 3.5
You need to install these packages first for net 8 to communicate with virtuoso
dotnet add package OpenLink.Data.Virtuoso
dotnet add package VirtuosoProvider
after that you can use them like this
using System.Data;
using OpenLink.Data.Virtuoso;
var connectionString = "Server=localhost;Port=1111;User ID=dba;Password=dba;Database=Virtuoso";
using (var conn = new VirtuosoConnection(connectionString))
{
conn.Open();
VirtuosoCommand cmd = conn.CreateCommand();
cmd.CommandText = "SPARQL SELECT * WHERE { ?s ?p ?o } LIMIT 10";
using (VirtuosoDataReader reader = cmd.ExecuteReader())
{
while (reader.Read())
{
Console.WriteLine(reader[0] + " " + reader[1] + " " + reader[2]);
}
}
}
