C# 开发的COM对象注册问题

wxl_pilot 2007-02-01 11:12:15

使用C#（.net 2.0）开发了一个插件后，按照MSDN提示注册插件
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wmsrvsdk/htm/registeringnetplugin.asp

regasm 提示 Assembly exported to "**/**/**.tlb" and the type library was registered successfully

但是在注册表下根本就没有找到注册的键值

各位有知情的么？

看到一个老外的文章http://www.csharpfriends.com/Articles/getArticle.aspx?articleID=113
说可能是因为没有默认参数为空的构造函数造成的
不过我这里已经有了public PreventDownload()
{ }

@hdt(倦怠)

先使用tlbexp LiveeduPreventDownload.dll
得到了LiveeduPreventDownload.tlb
使用regasm LiveeduPreventDownload.tlb
报错：fail to load (**/**/LiveeduPreventDownload.tlb) because it is not a valid .net assembly

真相重于对错 2007-02-01

另外想被别的程序看到使用强名称

好像不能直接regasm .net dll
应该先
tlbexp 到出类型库
regasm 注册类型库

按照MSDN的说明，是进行了注册表操作的，如类中的RegisterFunction方法

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wmsrvsdk/htm/registeringnetplugin.asp

我是先将这个编译好的DLL[LiveeduPreventDownload.dll]拷贝到<%systemroot%>/system32/windows media/server/下
再调用regasm LiveeduPreventDownload.dll /tlb
然后就提示我
Assembly exported to "**/**/**.tlb" and the type library was registered successfully

完了注册表里没信息，WINDOWS MEDIA SERVICE里也没发现注册好的插件

另外说明下：
直接使用 regasm LiveeduPreventDownload.dll命令会报错：no types were registered

regasm 注册完默认的inprocsever32值为 Mscoree.dll ，也就是.net 核心dll
你调用时
时通过

inprocserver32下的
class 和 assembly 键值确定的

把类文件贴出来吧，大家帮我看看

public class PreventDownload
{
// Statics

public PreventDownload()
{ }

static PreventDownload()
{
PreventDownload.GUID = "13775D86-6049-4958-9308-000CFE07AFDB";
}

regHKLM.SetValue(null, "四三三");

regHKCR.SetValue("Name", "四三三");
regHKCR.SetValue("Author", "四三三");
regHKCR.SetValue("CopyRight", "Copyright 2007 . All rights reserved");
regHKCR.SetValue("Description", "四三三");
}
catch (Exception ex)
{
MessageBox.Show(ex.Message, "注册出现异常！", MessageBoxButtons.OK, MessageBoxIcon.Hand);
return;
}
finally
{
regHKLM.Close();
regHKCR.Close();
}
}
