VB.NET - 替代Array.Contains？ [英] VB.NET - Alternative to Array.Contains?

问题描述

在，我用这个上的.NET Framework 3.5和它的正常工作：

Before, I use this on .NET Framework 3.5 and it's working fine:

    If (New String() {"ER", "PM", "EM", "OC"}).Contains(Session("Position")) Then
        'Some codes
    End If

现在我做的，与.NET 2.0及以上code未运行工作的一个项目，它给了我这样的：

Now I am doing a project that runs with .NET 2.0 and the code above is not working, it's giving me this:

'Contains' is not a member of 'System.Array'.

我怎样才能达到codeS上面（。载）不迁移从2.0到3.0吗？任何替代方案？

How can I achieve the codes above (.Contains) without migrating from 2.0 to 3.0? Any alternatives?

推荐答案

您将不得不重写你的code，像这样......

You will have to rewrite your code, like so...

If (Array.IndexOf(New String() {"ER", "PM", "EM", "OC"}), Session("Position")>-1) Then
        'Some codes
End If

该集合初始化是依赖于编译器，而不是框架对象而定，所以这应该工作。

The collection initializer is depends on the compiler, but not the framework being targetted, so this should work.

编辑：固定错误的方法/条件。我得到了interupted与作为我工作的这一点，并不意味着将它张贴，直到我已经证实了它的工作原理漏水下沉。

fixed wrong method/ condition. I got interupted with a leaky sink as I was working on this, and didn't mean to post it until I'd verified that it works.
