C# Lambda 转换为 VB

您好，我一直在查看有关 Sharparchitecture 的某些教程，但没有成功（在线转换器似乎无法做到这一点）：

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>();
    };
}

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>();
    };
}

我假设您正在尝试将其转换为 VB.Net。

在 Visual Basic 2010 之前（当前为测试版），这是不可能的。

VB.Net 2008 中的 Lambda 表达式只能保存单个表达式。

但是，您可以创建完成工作并返回它们的共享辅助函数。

例如：（在VB中）

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

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
