How to run regasm.exe from command line other than Visual Studio command prompt?

Question

I want to run regasm.exe from cmd. which is available in c:\windows\Microsoft.net\framework\2.057

I do like this c:\ regasm.exe

It gives regasm is not recognized as internal or external command.

So I understood that I need to set the path for regasm.exe in environment variable.

For which variable do I need to set the path to run regasm as described above?

Solution 1

Like Cheeso said:

You don't need the directory on your path. You could put it on your path, but you don't NEED to do that. If you are calling regasm rarely, or calling it from a batch file, you may find it is simpler to just invoke regasm via the fully-qualified pathname on the exe, eg:

%SystemRoot%\Microsoft.NET\Framework\v2.0.50727\regasm.exe MyAssembly.dll

Solution 2

If you created the DLL using .net 4.5 , then copy and paste this command on command prompt.

 %SystemRoot%\Microsoft.NET\Framework\v4.0.30319\regasm.exe MyAssembly.dll

Solution 3

I use this as post-build event in Visual Studio:

call "%VS90COMNTOOLS%vsvars32.bat"
regasm  $(TargetPath) /tlb

Depending on your Visual Studio version, use these environment variables instead:

1. Visual Studio 2008: VS90COMNTOOLS
2. Visual Studio 2010: VS100COMNTOOLS
3. Visual Studio 2012: VS110COMNTOOLS
4. Visual Studio 2013: VS120COMNTOOLS
5. Visual Studio 2015: VS140COMNTOOLS
6. Visual Studio 2017: VS150COMNTOOLS

I really dislike the hard coding of paths to get to regasm, when you install a new .Net or run on a machine with a different version, you need to ensure you find a version of regasm. Here's a solution to find the regasm.exe from the most current .Net installed regasm.

Within a bat file:

for /f %%a in ('dir %windir%\Microsoft.Net\Framework\regasm.exe /s /b') do set currentRegasm="%%a"
%currentRegasm% "full\path\to\your.dll" /options

Outside of a bat file (i.e. command prompt), just use %a instead of %%a

Is the little change to Cheeso's answer worth a separate one?
