SolrNet package from Nuget Packages in C# provides a simple way of achieving this. The documentation helps. Here's an example,

public async Task SolrFaceting()
    {
        Console.WriteLine("facets");
        var facetQuery = await _solr.QueryAsync(SolrQuery.All, new QueryOptions
        {
            Rows = 0,
            Facet = new FacetParameters
            {
                Queries = new[]
                {
                    new SolrFacetFieldQuery("FieldName1"),
                    new SolrFacetFieldQuery("FieldName2"),
                    new SolrFacetFieldQuery("FieldName3"),
                    new SolrFacetFieldQuery("FieldName4"),
                },
                Limit = 10

            }
        });

        foreach (var facet in facetQuery.FacetFields["FieldName1"]) {
            Console.WriteLine("{0}: {1}", facet.Key, facet.Value);
        }
        foreach (var facet in facetQuery.FacetFields["FieldName2"]) {
            Console.WriteLine("{0}: {1}", facet.Key, facet.Value);
        }
        foreach (var facet in facetQuery.FacetFields["FieldName3"]) {
            Console.WriteLine("{0}: {1}", facet.Key, facet.Value);
        }
        foreach (var facet in facetQuery.FacetFields["FieldName4"]) {
            Console.WriteLine("{0}: {1}", facet.Key, facet.Value);
        }
    }
