VB.NET System.Reflection.TargetParameterCountException程序集加载

Question

当我尝试调用程序集（vb.net windows窗体应用程序）时，我收到错误“System.Reflection.TargetInvocationException”或“System.Reflection.TargetParameterCountException”。 “confusethis.exe”来源：

Public Class mainform
Private Sub mainform_Load(sender As Object, e As EventArgs) Handles MyBase.Load
MsgBox("test")
End Sub
End Class

这是我调用的来源：

    Dim instance As FileStream = File.Open("confusethis.exe", FileMode.Open)
    Dim br As New BinaryReader(instance)
    Dim bin As Byte() = br.ReadBytes(Convert.ToInt32(instance.Length))
    instance.Close()
    br.Close()
    Dim a As Assembly = Assembly.Load(bin)
    Dim method As MethodInfo = a.EntryPoint
    If (IsDBNull(method) = False) Then
        Dim o As Object = a.CreateInstance(method.Name)
        method.Invoke(o, New Object() {New String() {"param1"}})
    Else
        MsgBox("error!")
    End If

我试过改变 method.Invoke(o, New Object() {New String() {"param1"}}) 至 method.Invoke(o, Nothing) 和 method.Invoke(Nothing, Nothing) 和 method.Invoke(o, New Object() {})

没有任何帮助，仍然有错误。
