How to get Solr result as per their scores

问题:

I am working on Solr with ASP.Net MVC.

I want to display result as per score result. It means if I search for any keyword, it gives me total 500 result. But I want only first 100 Results. I also display scores for results using following query:

Fields = new[] {"*","score"},

I want results which have score more than 0.3

How can I do this in Solr? Also a solrnet query to get this result.

Please advise. Thank you.
