使用C#.net DLL对象的经典ASP不支持此属性或方法 [英] Classic ASP using C# .net DLL Object doesn't support this property or method

问题描述

嘿，这是我第一次为经典的ASP页面创建COM对象.

Hey all this is my first time creating a COM object for a classic asp page.

创建此COM DLL时遵循的过程是:

The process I followed when creating this COM DLL is this:

1)使用强名称工具(sn.exe)并将.snk文件放置在应用程序内. (sn -k myKey.snk)

1) Used the Strong Name Tool (sn.exe) and placed the .snk file within the app. (sn -k myKey.snk)

2)已添加:

[assembly: AssemblyKeyFile(@"myKey.snk")]
[assembly: ComVisible(true)]

到AssemblyInfo.cs.我确实在KeyFile上收到了一个警告，说:

to the AssemblyInfo.cs. I do get a warning on the KeyFile saying:

使用命令行选项'/keyfile'或适当的项目设置 而不是"AssemblyKeyFile"

Use command line option '/keyfile' or appropriate project settings instead of 'AssemblyKeyFile'

3)从管理员处运行以下命令:SDK命令提示符:

3) Ran the following from the Administrator: SDK Command Prompt:

tlbexp c:\\temp\\dll\\classicASPWSEnDecrypt.dll /out:c:\\temp\\dll\\classicASPWSEnDecrypt.tlb

regasm /tlb:c:\\temp\\dll\\classicASPWSEnDecrypt.tlb c:\\temp\\dll\\classicASPWSEnDecrypt.dll

gacutil /i c:\\temp\\dll\\classicASPWSEnDecrypt.dll

regasm c:\\temp\\dll\\classicASPWSEnDecrypt.dll /codebase

所有注册都很好，没有错误.

All registered just fine without errors.

在我的经典ASP页面中，我有:

In my classic ASP page i have:

<%
 Dim classicEnDecrypt
 Set classicEnDecrypt = Server.CreateObject("classicASPWSEnDecrypt.Class1")

 response.write(classicEnDecrypt.Encrypt("testing"))
%>

我发现 ProgID (使用OLEView)为Class1，如下所示:

I found that the ProgID (using OLEView) was Class1 as seen below:

我的C#代码(仅是一个片段)是这样:

And my C# code (just a snip) is this:

namespace classicASPWSEnDecrypt
{
  public class Class1
  {
      public string Encrypt(string PlainText)
      {
         [code here]
      }

      public string Decrypt(string EncryptedText)
      {
         [code here]
      }
  }
}

一旦我在本地计算机(IIS7/Windows 7 Enterprise)上运行ASP页面，就会出现此错误:

Once I run the ASP page on my local machine (IIS7/Windows 7 Enterprise) I get this error:

Microsoft VBScript运行时错误'800a01b6'

Microsoft VBScript runtime error '800a01b6'

对象不支持以下属性或方法:'Encrypt'

Object doesn't support this property or method: 'Encrypt'

/contactupdateWS.asp，第49行

/contactupdateWS.asp, line 49

不太确定为什么知道我知道我为什么没有加密功能?！

Not quite sure why it says I don't have Encrypt function when I know I do?!

我可能会缺少什么?

推荐答案

我已经在注释中提供了一些信息.

I already provided some information in comment.

我也觉得您不应该为此使用静态方法.看来com不支持静态方法.

I also feel that you should not have static method for this. It seems that com does not support static method.

还使用Server.CreateObject方法创建类的对象，因此很明显，您应该为此使用实例方法.

Also you are creating object of class by using Server.CreateObject method so it is quite obvious that you should have instance method for this.

public class Class1
  {
     public string Encrypt(string PlainText)
     {
     [code here]
     }

     public string Decrypt(string EncryptedText)
     {
     [code here]
     }
   }
