推荐答案

您可以尝试此

You could try this

If e.PropertyName = GetPropertyName(Function() Customer.FirstName) Then
End If

功能:-

Function:-

Public Function GetPropertyName(Of T)(ByVal expression As Expressions.Expression(Of Func(Of T))) As String
    Dim memberExpression As Expressions.MemberExpression = DirectCast(expression.Body, Expressions.MemberExpression)
    Return memberExpression.Member.Name
End Function

让我知道这是否有效，因为它不在我的脑海！

Let me know if this works, as this is off the top of my head!
