Basic usage
　　First, we have to map the Solr document to a class. Let's use a subset of the default schema that comes with the Solr distribution:



public class Product {
    [SolrUniqueKey("id")]
public string Id { get; set; }
    [SolrField("manu_exact")]
public string Manufacturer { get; set; }
    [SolrField("cat")]
public ICollection Categories { get; set; }
    [SolrField("price")]
public decimal Price { get; set; }
    [SolrField("inStock")]
public bool InStock { get; set; }
}

　　It's just a POCO with some attributes: SolrField maps the attribute to a Solr field and SolrUniqueKey (optional but recommended) maps an attribute to a Solr unique key field.
　　Now we'll write some tests using this mapped class. Let's initialize the library:



[TestFixtureSetUp]
public void FixtureSetup() {
Startup.Init("http://localhost:8983/solr");
}

　　Let's add a document (make sure you have a running Solr instance before running this test):



[Test]
public void Add() {
var p = new Product {
Id = "SP2514N",
Manufacturer = "Samsung Electronics Co. Ltd.",
Categories = new[] {
"electronics",
"hard drive",
},
Price = 92,
InStock = true,
};
var solr = ServiceLocator.Current.GetInstance();
solr.Add(p);
solr.Commit();
}

　　Let's see if the document is where we left it:



[Test]
public void Query() {
var solr = ServiceLocator.Current.GetInstance();
var results = solr.Query(new SolrQueryByField("id", "SP2514N"));
Assert.AreEqual(1, results.Count);
Console.WriteLine(results[0].Price);
}
