完全限定类型名称的GetType不起作用

Question

Public Sub New(ByVal oldC As Control)
    Dim FQTN As String = oldC.GetType.FullName
    Dim t As Type = Type.GetType(FQTN)
    Dim newC As Object = Activator.CreateInstance(t)
End Sub

FQTN返回正确的类型名称，但t为Nothing。例如，FQTN = System.Windows.Forms.Panel。

Answer 1

摆脱FQTN。

这适用于您正在寻找

的面板示例

Public Sub New(ByVal oldC As Control)
    Dim t As Type = oldC.GetType()
    Dim newC As Object = Activator.CreateInstance(t)
End Sub

此外，这是Type.GetType("namespace.a.b.ClassName") returns null
