How do I programmatically find ILASM.EXE in .NET 4.0?

Question

My program needs to call ILASM , but it keeps moving on me. Is there a registry setting or some other value that my program can read so I don't need to hard code the path?

Answer 1

From the SDK Microsoft.Build.Utilities namespace, the ToolLocationHelper class can be used like so:

using Microsoft.Build.Utilities; 

// Use ToolLocationHelper to find ILASM.EXE in the Framework directory
ToolLocationHelper.GetPathToDotNetFrameworkFile("ILAsm.exe", TargetDotNetFrameworkVersion.VersionLatest);

Taken from MSDN sample .

Answer 2

There seem to be a few libraries that are like ILAsm that people have recommended:

You might want to use those (or CodeDom -> C#) instead of calling out to a program.

HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft.NETFramework, look for InstallRoot. Add the .net version number to the path in InstallRoot and you've got it.
