AnonymousType_0`2 [System.Int32，System.String]] ''以键入``System.Collections.Generic.IEnumerable`1 [WindowsApplication1.Countrys]''.

AnonymousType_0`2[System.Int32,System.String]]'' to type ''System.Collections.Generic.IEnumerable`1[WindowsApplication1.Countrys]''.

public class Countries

找到了解决方案！

Thanks

FOUND A SOLUTION!

Dim test As IEnumerable(Of Countrys) = (From t In dt.Tables("Test").AsEnumerable _
                   Select New Countrys With {.CountryID = t.Field(Of Integer)(0), .Country = t.Field(Of String)(1)}).ToList

现在进入下一个阶段，允许方法对任何表/对象列表执行此操作

now on to the next stage to allow a method to do this for any table / list of objects

通常，这是通过调用Cast<>()完成的.我不知道如何调用VB语法，因此请查看以下页面:

Typically this is done with a call to Cast<>(). I don''t know the VB syntax to call it, so check this page out:

我将更改Select方法以直接创建国家列表.在C#中，它看起来像这样(我确定您可以将其转换为VB):

I would change the Select method to create a list of Countries directly. In C# it would look like this (I''m sure you''ll be able to convert it to VB):

List<Countries> test = (....).Select(t => new Countries() {CountyID = ..., Country = ...}).ToList()

基本上，不是在Select语句内创建匿名对象，而是创建类型为Countries的对象.

Basically, instead of creating an anonymous object inside the Select statement, create an object of type Countries.
