[英]Trying to using Nhibernate with Mono & SQLite - can't find System.Data.SQLite
I wrote a simple app in mono (C#) that uses NHibernate with MYSQL - and I now want to port it to SQLite.我在 mono (C#) 中写了一个简单的应用程序,它使用 NHibernate 和 MYSQL - 我现在想将它移植到 Z4977757A9C70B51EC1
My hope is (was) that I could simply change hibernate.cfg.xml and point it to a different database.我的希望是(曾经)我可以简单地更改 hibernate.cfg.xml 并将其指向不同的数据库。 Here is my modified hibernate.cfg.xml:
这是我修改后的 hibernate.cfg.xml:
<?xml version="1.0" encoding="utf-8" ?>
<hibernate-configuration xmlns="urn:nhibernate-configuration-2.2" >
<session-factory name="NHibernate.Test">
<property name="connection.driver_class">NHibernate.Driver.SQLite20Driver</property>
<property name="connection.connection_string">
Data Source=nhibernate_test.db;Version=3
</property>
<property name="dialect">NHibernate.Dialect.SQLiteDialect</property>
<property name="query.substitutions">true=1;false=0</property>
<property name="proxyfactory.factory_class">NHibernate.ByteCode.LinFu.ProxyFactoryFactory, NHibernate.ByteCode.LinFu</property>
</session-factory>
</hibernate-configuration>
The problem is that I'm getting an error to the effect that it can't find System.Data.SQLite.问题是我收到一个错误,它无法找到 System.Data.SQLite。 This doesn't surprise me since, as I understand it, in mono we should be using Mono.Data.SQLite.
这并不让我感到惊讶,因为据我了解,在 mono 中,我们应该使用 Mono.Data.SQLite。
The trouble is (assuming I'm understanding the problem correctly) I don't know how to tell NHibernate to use Mono.Data.SQLite instead of System.Data.SQLite.

This is all being done on Linux - if that makes any difference.这一切都在 Linux 上完成 - 如果这有什么不同的话。
Does anyone have any ideas how to proceed?有谁知道如何进行?
You need to make nHibernate aware of the Mono.Data.SQLite assembly.您需要让 nHibernate 了解 Mono.Data.SQLite 程序集。 Add this to the configuration:
将此添加到配置中:
<add key="connection.driver_class" value="Name.Space.MonoSqliteDriver, AssemblyName" />
And you also need a simple MonoSQLiteDriver
class:你还需要一个简单的
MonoSQLiteDriver
class:
public class MonoSqliteDriver : NHibernate.Driver.ReflectionBasedDriver
{
public MonoSqliteDriver() :
base("Mono.Data.Sqlite",
"Mono.Data.Sqlite.SqliteConnection",
"Mono.Data.Sqlite.SqliteCommand")
{
}
public override bool UseNamedPrefixInParameter {
get {
return true;
}
}
public override bool UseNamedPrefixInSql {
get {
return true;
}
}
public override string NamedPrefix {
get {
return "@";
}
}
public override bool SupportsMultipleOpenReaders {
get {
return false;
}
}
}

Note that you might need to use 4 parameters instead of 3 for the call to the constructor of the ReflectionBasedDriver base class, see Using NHibernate and Mono.Data.Sqlite Note that you might need to use 4 parameters instead of 3 for the call to the constructor of the ReflectionBasedDriver base class, see Using NHibernate and Mono.Data.Sqlite
