C# 到 VB.net List的转换有错误

发布于 2024-09-24 02:02:22 字数 412 浏览 7 评论 0原文

我正在尝试将一些 C# 代码转换为 VB，但出现错误。正确的 VB 语法是什么？

return new List<string>   {"First Name", "Last Name", "First & Last Name", "None"};

Return New List(Of String)() From {"First Name", "Last Name", "First & Last Name", "None"}

我也可以转换它怎么样？暗淡列表作为新列表（国家/地区）（）来自{新国家/地区（）与{Key .Name =“选择国家/地区”，Key .Code =“0”}}

谢谢

I'm trying to convert some C# code to VB but I’m getting an error. What would be the correct VB syntax?

return new List<string>   {"First Name", "Last Name", "First & Last Name", "None"};

Return New List(Of String)() From {"First Name", "Last Name", "First & Last Name", "None"}

And how about would I convert this too?
Dim list As New List(Of Country)() From { New Country() With { Key .Name = "Select Country", Key .Code = "0" } }

Thanks

VB10（Visual Studio 2010 的一部分）支持集合初始化，但 VB9 (VS 2008) 不支持。您发布的语法对于 VB10 是正确的。

Dim foos As New List(Of String)() From {"Foo", "Bar"}

在VB9中，您只需要以老式的方式处理它

Dim foos as New List(of String)()
foos.Add("Foo")
foos.Add("Bar")

VB9确实支持数组初始化

Dim foos As String() = New String() {"Foo", "Bar"}

但是，数组的功能不如List(of T)，但如果您不需要添加或者删除元素，您当然可以使用数组而不是列表。

Collection initialization is supported in VB10 (part of Visual Studio 2010), but not in VB9 (VS 2008). The syntax you posted is correct for VB10.

Dim foos As New List(Of String)() From {"Foo", "Bar"}

In VB9, you would just need to handle it the old fashioned way

Dim foos as New List(of String)()
foos.Add("Foo")
foos.Add("Bar")

VB9 does support array initialization

Dim foos As String() = New String() {"Foo", "Bar"}

However, the array is not as functional as the List(of T), but if you do not need to add or remove elements, you can certainly use an array instead of the list.
