'''NHibernate'''是一个面向[[.NET框架]]的[[对象关系映射]]解决方案。主要用来把对象模型表示的对象映射到基于SQL的关系模型数据结构中去。

NHibernate，顾名思义，如同NUnit，NAnt一样，是基于.Net的[[Hibernate]]实现。

== 例子 ==
這裡有程式碼片段，是要使用NHibernate將物件加入資料庫，和展示如何取得、修改、更新資料庫中的物件。
<syntaxhighlight lang="csharp">
//Add a Customer to the datastore

//'sessionFactory' is a thread-safe object built once per application lifetime (can take seconds to build)
//based on configuration files which control how database tables are mapped to C# objects
//(e.g. which property maps to which column in a database table)
//
//'session' is not thread safe and fast to obtain and can be thought of as a connection to the database
using (var session = sessionFactory.OpenSession())
{
//transaction represents a db transaction
using (ITransaction transaction = session.BeginTransaction())
{
//The line below adds the customer to NHibernate's list of objects to insert to the database
//but it doesn't execute SQL insert command at this stage*.
//*if the Id field is generated by the database (e.g. an auto-incremented number)
//then NHibernate will execute SQL INSERT when .Save is called
session.Save(new Customer { Id = Guid.NewGuid(), FirstName = "Boss", Age = 50 });

//The call below will execute the SQL INSERT and commit the transaction
transaction.Commit();
}
}

//Retrieve the Customer from the database, modify the record and update the database
using (var session = sessionFactory.OpenSession())
{
using (ITransaction transaction = session.BeginTransaction())
{
//session's Query returns IQueryable<Customer>.
//Only when .FirstOrDefault is called will NHibernate execute the SQL query
Customer customer = session.Query<Customer>().Where(c => c.Token == token ).FirstOrDefault();

//Now the customer is 'part of' the 'session' object and NHibernate keeps track of changes
//made to it
if( customer != null )
{
//Changing a property of an object does NOT cause SQL to be executed
customer.TokenVerified = true;

//Committing the transaction results in an SQL UPDATE statement
//NHibernate kept track of the fact that 'customer' has been changed since loading
transaction.Commit();
}
}
}

</syntaxhighlight>

NHibernate's configuration may affect when NHibernate executes SQL statements.
