来自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 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"） 返回 null 的副本
