C# Can'；t将其转换为VB.net

我正在尝试将以下内容转换为vb.net。提前谢谢

   Categories.DataSource = objDT.Rows.Cast<DataRow>()
        .Select(r => new { Attendee = r.Field<string>("Attendee"), Item = r.Field<string>("Item") })
        .GroupBy(v => v.Attendee)
        .Select(g => new { Attendee = g.Key, Item = g.ToList() });

或

试试下面的方法

Categories.DataSource = objDT.Rows.Cast(Of DataRow)() _
    .Select(Function(r) New With {.Attendee = r.Field(Of String)("Attendee"), .Item = r.Field(Of String)("Item")}) _
    .GroupBy(Function(v) v.Attendee) _
    .Select(Function(g) New With { .Attendee = g.Key, .Item = g.ToList()})

试试这个：

  Categories.DataSource = objDT.Rows.Cast(Of DataRow)().Select(Function(r) New With { _
 .Attendee = r.Field(Of String)("Attendee"), _
 .Item = r.Field(Of String)("Item") _
}).GroupBy(Function(v) v.Attendee).Select(Function(g) New With { _
 .Attendee = g.Key, _
 .Item = g.ToList() _
})

对象类（带{}的新对象（）与匿名类型（带{}的新对象）不同

您以后可以使用此网站：。它对大多数转换都很有效。

谢谢Matthieu，这种方法很有效！我会记得尝试上面的转换链接。谢谢JaredPar，你的解决方案也同样有效！我也可以给你绿色的复选标记。谢谢：）
