在db4o中打开具有重命名名称空间/程序集的对象

wiki documentation .

这是临时的做法:

TypeAlias alias = new TypeAlias("OldNameSpace.OldTypeName, OldAssembly", "NewNameSpace.NewTypeName, NewAssembly");
Db4oFactory.Configure().AddAlias(alias);
IObjectContainer db = Db4oFactory.OpenFile(dbfilename);

using (IObjectContainer db = Db4oFactory.OpenFile(dbfilename))
{
    var n = db.Ext().StoredClasses();
    foreach (var x in n)
    {
        System.Diagnostics.Debug.WriteLine(x.GetName());
    }
    var c1 = db.Ext().StoredClass("OldNameSpace.OldType, OldAssembly");//
    if (c1 != null)
        c1.Rename("NewNameSpace.OldType, NewAssembly");

    var c2 = db.Ext().StoredClass("System.Collections.Generic.List`1[[OldNameSpace.OldType, OldAssembly]], mscorlib");
    if (c2 != null)
        c2.Rename("System.Collections.Generic.List`1[[NewNameSpace.OldType, NewAssembly]], mscorlib");
}
