vb.net – 在New语句之后调用实例方法内联

public void SetBooks(IEnumerable<Book> books)
    {
        if (books == null)
            throw new ArgumentNullException("books");

        new System.Xml.Linq.XDocument(books).Save(_filename);
    }

在http://converter.telerik.com/它说：

Public Sub SetBooks(books As IEnumerable(Of Book))
        If books Is Nothing Then
            Throw New ArgumentNullException("books")
        End If
        New System.Xml.Linq.XDocument(books).Save(_filename)
End Sub

但是visual studio说“语法错误”.因为“新”

这种情况的关键字是什么,我在Google上搜索但没有结果.

Dim doc = New System.Xml.Linq.XDocument(books)
doc.Save(_filename)

在C#中构造函数returns the instance of the created object,在VB.NET中没有.
