VB.NET Array包含方法不起作用 [英] VB.NET Array Contains method does not work

问题描述

在VB.NET我试图确定在一个字符串数组存在一个给定的字符串。根据我的研究阵中拥有'包含'，我可以使用的方法，所以code看起来是这样的：

In VB.NET I am trying to determine in a given string exists in a String Array. According to my research the Array has a 'Contains' method that I can use, so the Code looks something like this:

Dim fileTypesZ As String() = {"PDF", "TXT", "DOC", "DOCX", "XLS", "XLSX", "JPG", "JPGE", "BMP", "GIF"}

If (fileTypesZ.Contains(tempTest)) Then

End If

然而，VB.NET是说'包含'不'的System.Array的成员。有没有我可以使用另一种方法？

However, VB.NET is saying 'Contains' is not a member of 'System.Array'. Is there another method that I can use?

推荐答案

有没有包含在阵列，但有<一个href=\"http://msdn.microsoft.com/en-us/library/system.linq.enumerable.contains.aspx\"><$c$c>Enumerable.Contains,这是一个扩展方法对数组的作品。

There is no Contains on Array, but there is Enumerable.Contains, which is an extension method that works on arrays.

请确保包括进口System.Linq的你的文件的顶部，而你引用 System.Core.dll 在您的项目引用。

Make sure to include Imports System.Linq at the top of your file, and that you're referencing System.Core.dll in your project references.
