Question

Hi I have been looking at certain tutorials on sharparchitecture and trying to no avail (the online convertors don’t seem to be able to do this):

private Action<AutoMappingExpressions> GetSetup()
{
    return c =>
    {
        c.FindIdentity = type => type.Name == "Id";
    };
}

private Action<IConventionFinder> GetConventions()
{
    return c =>
    {
        c.Add<MVCTemp.Data.NHibernateMaps.Conventions.ForeignKeyConvention>();
        c.Add<MVCTemp.Data.NHibernateMaps.Conventions.HasManyConvention>();
        c.Add<MVCTemp.Data.NHibernateMaps.Conventions.HasManyToManyConvention>();
        c.Add<MVCTemp.Data.NHibernateMaps.Conventions.ManyToManyTableNameConvention>();
        c.Add<MVCTemp.Data.NHibernateMaps.Conventions.PrimaryKeyConvention>();
        c.Add<MVCTemp.Data.NHibernateMaps.Conventions.ReferenceConvention>();
        c.Add<MVCTemp.Data.NHibernateMaps.Conventions.TableNameConvention>();
    };
}

I assume that you’re trying to convert this to VB.Net.

Until Visual Basic 2010 (currently in beta), it’s not possible.

Lambda expressions in VB.Net 2008 can only hold a single expression.

However, you could create Shared helper functions that do the work and return them.

For example: (In VB)

Function GetConventions() As Action(Of IConventionFinder) 
    Return AddressOf GetConventionsHelper
End Function

Shared Sub GetConventionsHelper(c As IConventionFinder)
    c.Add(Of MVCTemp.Data.NHibernateMaps.Conventions.ForeignKeyConvention)()
    c.Add(Of MVCTemp.Data.NHibernateMaps.Conventions.HasManyConvention)()
    c.Add(Of MVCTemp.Data.NHibernateMaps.Conventions.HasManyToManyConvention)()
    c.Add(Of MVCTemp.Data.NHibernateMaps.Conventions.ManyToManyTableNameConvention)()
    c.Add(Of MVCTemp.Data.NHibernateMaps.Conventions.PrimaryKeyConvention)()
    c.Add(Of MVCTemp.Data.NHibernateMaps.Conventions.ReferenceConvention)()
    c.Add(Of MVCTemp.Data.NHibernateMaps.Conventions.TableNameConvention)()
End Sub
