vba实现：编写一个方法，传入一个字符串，若字符串中存在“白|橙|褐|黑|红|黄|灰|蓝|绿|棕|棕白|淡蓝|蓝白|黄绿|绿白|橙白|紫|粉红|浅蓝|浅绿|紫白|绿黑|黄黑|红黑|白黑|粉黑|灰黑|橙黑|浅绿黑|浅蓝黑”，返回删除这些字符后的子串

在VBA中，可以使用Replace函数来删除字符串中指定的字符。以下是一个示例方法，用于删除字符串中存在的特定颜色字符：

Public Function RemoveColors(ByVal inputString As String) As String
    Dim colors As Variant
    colors = Array("白", "橙", "褐", "黑", "红", "黄", "灰", "蓝", "绿", "棕", "棕白", "淡蓝", "蓝白", "黄绿", "绿白", "橙白", "紫", "粉红", "浅蓝", "浅绿", "紫白", "绿黑", "黄黑", "红黑", "白黑", "粉黑", "灰黑", "橙黑", "浅绿黑", "浅蓝黑")
    
    Dim i As Integer
    For i = LBound(colors) To UBound(colors)
        inputString = Replace(inputString, colors(i), "")
    Next i
    
    RemoveColors = inputString
End Function

使用示例：

Sub Main()
    Dim input As String
    input = "这是一个字符串，其中包含红色和蓝色。"
    
    Dim result As String
    result = RemoveColors(input)
    
    Debug.Print result ' 输出：这是一个字符串，其中包含和。
End Sub
