VBA 中的类（静态）方法

在VBA中，类（静态）方法是一种非常强大的工具，它们允许我们在代码中创建可重复使用的函数和过程。这些方法可以在类模块中定义，并且不需要实例化类就可以调用。在本文中，我们将探讨如何使用这些类（静态）方法，并提供一些实际的案例代码。

Option Explicit
Public Class DateUtils
    Public Shared Function ConvertStringToDate(ByVal dateString As String) As Date
        On Error Resume Next
        ConvertStringToDate = CDate(dateString)
    End Function
End Class
Sub TestDateConversion()
    Dim dateString As String
    Dim convertedDate As Date
    
    dateString = "2021-01-01"
    convertedDate = DateUtils.ConvertStringToDate(dateString)
    
    MsgBox "Converted Date: " & convertedDate
End Sub

Option Explicit
Public Class StringUtils
    Public Shared Function RemoveSpaces(ByVal inputString As String) As String
        RemoveSpaces = Replace(inputString, " ", "")
    End Function
End Class
Sub TestStringProcessing()
    Dim inputString As String
    Dim processedString As String
    
    inputString = "Hello World"
    processedString = StringUtils.RemoveSpaces(inputString)
    
    MsgBox "Processed String: " & processedString
End Sub
