I use NHibernate 4.0.2.4000. I'm creating a mapping using PropertyInfo:
PropertyInfo[] props = classType.GetProperties();
foreach (PropertyInfo prop in props)
{
/* some code */
Bag(prop.Name, collectionMapping =>
{
collectionMapping.Table(prop.Name + "_" + classType.Name +"_Rel");
collectionMapping.Key(k => k.Column(prop.Name + "_Id"));
},
mapping => mapping.ManyToMany(p => p.Column(classType.Name + "_Id")));
/* some code */
}
But the "Bag" returns an error: *The type arguments for method [...] cannot
be inferred from the usage. Try specifying the type arguments explicitly*.
I know that I have to use Bag<TElement>() but I don't have TElement.
Methods (Id(), Property()) work well. The method ManyToOne() is in the same
situation.
I tried to use it:
this.GetType()
.GetMethod("Bag")
.MakeGenericMethod(prop.PropertyType)
.Invoke(this, new object[]{ prop.Name, [...], [...] });
but delegates are too complicated.
Maybe someone knows another solution? Please don't propose to do map in the
xml in memory dynamically. Thanks.
