COM Interop .Net - 执行 asm 方法时出现内存不足/缓冲区溢出错误

这是一个奇怪的现象。很长一段时间以来，我开发的应用程序一直在使用 com interop 在经典 ASP 应用程序中使用 .Net 类型。我今天再次启动这个应用程序来查看一些问题，当访问这些对象之一的方法时，它出现内存不足错误。很好 - 我想，我只需注销该批次，检查注册表中是否有重复的条目（可能是更高版本），确保只有我期望的版本在 GAC 等中，然后重试。运气不好。好的，下一步可以用一个基本的 VB6 应用程序来完成这个任务吗？回答？是的！现在我很困惑。我在 Fusion 日志中没有看到任何与此相关的内容。下面是在 asp 和 VB6 表单中使用以下非常简单的代码来测试这一点：

**VB6**
Private Sub Form_Load()

    Dim dsf As MyTypeName
    Set dsf = CreateObject("MyNS.MyType")
    dsf.MyMethod "SOME TEXT" ' Works fine in VB6
End Sub

**ASP**
    Dim dsf
    Set dsf = Server.CreateObject("MyNS.MyType")
    dsf.MyMethod "SOME TEXT" ' Doesn't work in asp...

确切的错误：

Microsoft VBScript 运行时 (0x800A0007) 内存不足：“MyMethod”

大家有什么想法吗？

This is a strange one. For a long time now an application I develop on has been using com interop to use .Net types in an Classic ASP application. I fired this application up again today to look at some issue with it got an Out Of Memory error when accessing a method on one of these objects. Fine - I thought, I'll just unregister the lot, check for duplicate entries (for later versions perhaps) in the registry, ensure only the version I am expecting is in the GAC etc etc and try again. No luck. Ok, next step can a basic VB6 app do this task; answer? yes! Now I'm confused. I see nothing in the Fusion logs about this. Here is the following very simple code used in both the asp and the VB6 form to test this:

**VB6**
Private Sub Form_Load()

    Dim dsf As MyTypeName
    Set dsf = CreateObject("MyNS.MyType")
    dsf.MyMethod "SOME TEXT" ' Works fine in VB6
End Sub

**ASP**
    Dim dsf
    Set dsf = Server.CreateObject("MyNS.MyType")
    dsf.MyMethod "SOME TEXT" ' Doesn't work in asp...

The exact error:

Microsoft VBScript runtime (0x800A0007)
Out of memory: 'MyMethod'

Any ideas guys?
