C＃到VB.NET-使用接口

Question

嘿，我想知道這在VB.NET中如何

在C＃中

UserSettings vUsers = new UserSettings();
UserSettings.IUserSettings vUserI = (UserSettings.IUserSettings)vUsers

---

我有機會嘗試用VB.NET編寫它，對嗎？

在VB.NET中

Dim vUsers As UserSettings = New UserSettings()
Dim vUserI As UserSettings.IUserSettings = (UserSettings.IUserSettings)vUsers

Answer 1

它將在vb.Net中寫為：

Dim vUsers As New UserSettings()
Dim vUserI As UserSettings.IUserSettings = DirectCast(vUsers, UserSettings.IUserSettings)

此外，您可以嘗試將C＃轉換為VB.Net：

希望這可以幫助！！

Answer 2

您直接在c＃中進行轉換，因此我認為DirectCast將是此處使用的方法。

Dim vUsers As New UserSettings()

Dim vUserI As UserSettings.IUserSettings = DirectCast(vUsers, UserSettings.IUserSettings)
