在这篇文章中，我们将解释什么是RegAsm.exe，如何使用RegAsm.exe注册或注销^(RegAsm.exe)DLL，以及RegAsm.exe与^(RegAsm.exe)Regsvr32.exe的不同之处。

Windows 11/10RegAsm.exe是什么？

RegAsm 是Register Assembly的缩写形式。RegAsm.exe是微软^(Microsoft)开发的Windows正版组件。RegAsm.exe打开程序集注册^{(Assembly Registration)}工具。当程序集注册^{(Assembly Registration)}工具打开时，它会读取程序集中的元数据并将必要的条目添加到注册表中。RegAsm.exe只负责打开程序集注册^{(Assembly Registration)}工具。它不会对您的 PC 造成任何威胁。但是，在某些情况下，某些恶意软件会伪装成RegAsm.exe。

The Assembly Registration tool reads the metadata within an assembly and adds the necessary entries to the registry, which allows COM clients to create .NET Framework classes transparently. Once a class is registered, any COM client can use it as though the class were a COM class. The class is registered only once, when the assembly is installed. Instances of classes within the assembly cannot be created from COM until they are actually registered.

RegAsm.exe 是恶意软件吗？

有时，我们计算机上的防病毒程序可能会将Windows 操作系统^{(Windows OS)}的某些重要系统文件标记为威胁。这可能是误报，或者如果恶意软件通过使用相同的名称伪装成操作系统文件，则可能会发生这种情况。RegAsm.exe也可能发生这种情况！

如果您安装了任何盗版程序并且您的防病毒软件标记为RegAsm.exe，那么：

1. 彻底卸载盗版程序，不留任何痕迹
2. 使用防病毒和反恶意软件程序扫描您的 PC
3. ^(Delete)从您的 PC 中删除盗版安装程序或与之相关的文件

这样你就可以让你的电脑恢复正常。

为避免受恶意软件感染的RegAsm.exe进入您的 PC，请不要安装盗版Microsoft Office或Windows或任何其他程序。这是避免恶意软件并确保 PC 安全的唯一方法。

如何使用RegAsm.exe取消注册^(RegAsm.exe)DLL？

要运行该工具，请使用 Visual Studio Developer Command Prompt或 Visual Studio Developer PowerShell。使用RegAsm.exe取消注册DLL就像注册一样简单。

打开命令提示符^{(Command Prompt)}并运行以下命令，将<dllfilename>名称替换为您要取消注册的名称。

regasm /u <dllfilename>.dll

要完全注销DLL ，您还必须注销^(DLL)DLL的类型库。为此，请运行以下命令。

regasm <dllfilename> /tlb /unregister

RegAsm.exe 与Regsvr32.exe有何不同？

Regsvr32.exe是一个命令行工具，用于在注册表中注册DLL^(DLLs)和ActiveX控件。同时，RegAsm.exe使注册表项使 .NET 组件看起来像COM组件。RegAsm.exe随.NET SDK一起提供。

什么是 Regasm 代码库？

RegAsm Codebase命令行用于在注册表中为代码库创建一个条目。注册表中的代码库条目指定了未安装在全局程序集缓存上的程序集的路径。全局程序集缓存将程序集存储在您的 PC 上，供多个程序使用。使用代码库的程序集文件必须是强名称程序集，以避免与全局程序集缓存中的其他程序集发生冲突。

我们希望您今天在这里学到了一些新东西。

What is RegAsm.exe? How to unregister a dll using RegAsm.exe?

In this post, we explain what is RegAsm.exe, how to register or unregister a DLL using RegAsm.exe, and how RegAsm.exe is different from Regsvr32.exe.

What is RegAsm.exe in Windows 11/10?

RegAsm is the short form of Register Assembly. RegAsm.exe is a genuine component of Windows developed by Microsoft. RegAsm.exe opens the Assembly Registration tool. When the Assembly Registration tool is opened, it reads the metadata within an assembly and adds the necessary entries to the registry. RegAsm.exe is only responsible for opening the Assembly Registration tool. It does not pose any threat to your PC. However, there are some instances where some malware is camouflaged as RegAsm.exe.

The Assembly Registration tool reads the metadata within an assembly and adds the necessary entries to the registry, which allows COM clients to create .NET Framework classes transparently. Once a class is registered, any COM client can use it as though the class were a COM class. The class is registered only once, when the assembly is installed. Instances of classes within the assembly cannot be created from COM until they are actually registered.

Is RegAsm.exe malware?

Occasionally, the antivirus programs on our computer may flag some important system file of Windows OS as threats. It could be a false positive or it could happen if malware is masquerading as an OS file by taking the same name. This can happen with RegAsm.exe too!

If you have installed any program that is pirated and your antivirus flagged RegAsm.exe, then:

1. Uninstall the pirated program completely without any traces of it
2. Scan your PC with antivirus and anti-malware program
3. Delete the pirated installers or files related to it from your PC

This way you can get back your PC to normalcy.

To avoid malware-infected RegAsm.exe getting into your PC, don’t install pirated Microsoft Office, or Windows, or any other programs for that matter. This is the only way you can avoid the malware and make your PC secure.

How to Unregister a DLL using RegAsm.exe?

To run the tool, use Visual Studio Developer Command Prompt or Visual Studio Developer PowerShell. Unregistering a DLL using RegAsm.exe is so easy as registering.

Open Command Prompt and run the following command replacing the <dllfilename> name with the name you want to unregister.

regasm /u <dllfilename>.dll

To unregister the DLL completely, you have to unregister the type library of the DLL too. To do so, run the following command.

regasm <dllfilename> /tlb /unregister

How is RegAsm.exe different from Regsvr32.exe?

Regsvr32.exe is a command-line tool that is used to register DLLs and ActiveX controls in the registry. Meanwhile, RegAsm.exe makes registry entries to make .NET components look like COM components. RegAsm.exe comes with the .NET SDK.

What is Regasm Codebase?

RegAsm Codebase command line is used to create an entry for codebase in the registry. The codebase entry in the registry specifies the path for the assembly that is not installed on the global assembly cache. The global assembly cache stores assemblies on your PC that are used by multiple programs. The assembly file for which you use the codebase must be a strong-named assembly to avoid conflicts with others in the global assembly cache.
