How can I export the names of all the methods in an assembly?

Question

I am able to see all the methods in a referenced library in my object browser. I wish to export all these methods to a text file.

I also have access to dotPeek but I could not locate any export functionality in that software.

I've got to admit I'm not sure how you could do it in Visual Studio, but programatically you can use reflection:

System.IO.File.WriteAllLines(myFileName,
                System.Reflection.Assembly.LoadFile(myDllPath)
                    .GetType(className)
                    .GetMethods()
                    .Select(m => m.Name)
                    .ToArray());

ETA:

I'm not 100% if you want the methods in the screenshot or all the methods in the DLL so I've updated with the second variant:

 System.IO.File.WriteAllLines(myFileName,
                System.Reflection.Assembly.LoadFile(myDllPath)
                    .GetTypes()                    
                    .SelectMany(t => t.GetMethods())
                    .Select(m => m.Name)
                    .ToArray());

You can use PowerShell to get a list of types/methods in a given assembly.

$AssemblyList = [System.AppDomain]::CurrentDomain.GetAssemblies();

foreach ($Type in $AssemblyList[5].GetTypes()) {
    $MethodList = $Type.GetMethods();
    foreach ($Method in $MethodList) {
        $Type.Name + ' ' + $Method.Name;
    }
}

You can also do a reflection-only load on a particular file path:

$Assembly = [System.Reflection.Assembly]::ReflectionOnlyLoadFrom('c:\path\to\assembly.dll');

foreach ($Type in $Assembly.GetTypes()) {
    $MethodList = $Type.GetMethods();
    foreach ($Method in $MethodList) {
        $Type.Name + ' ' + $Method.Name;
    }
}
