我可以让我的函数在一页上运行，但是当我想从 App_Code 文件夹中调用该函数时，我在“CreateSentence”部分收到一个错误，说它引用了一个非共享成员。

如果有人有一个简单的共享函数示例（该函数位于 App_Code 文件夹中，而不是在同一页面上）或者可以指出错误，我会非常感激。

只需编辑要共享的函数：

Imports Microsoft.VisualBasic

Public Class Functions

    Public Shared Function CreateSentence(ByVal word As String) As String

        Dim Sentence As String = "The world you have is: " & word & "."

        Return Sentence

    End Function

End Class

您的功能应该共享：

Public Shared Function CreateSentence(ByVal word As String) As String
   Dim Sentence As String = "The world you have is: " & word & "."
   Return Sentence
End Function

然后您可以在您的页面中调用该函数Functions.CreateSentence：

Protected Sub Button1_Click(sender As Object, e As System.EventArgs) Handles Button1.Click
   sentence.Text = Functions.CreateSentence(word.Text)
End Sub
