Was making this for a project I'm working on and thought maybe someone might want something like this. It's pretty simple but efficient if you're trying to make multiple automated requests.

Just include FakeAgent.cs in your project (and change the namespaces of course), and add agent_list.json as a new file resource to your project (Encoding UTF-8, FileType Text).

FYI: This requires the NuGet package for Newtonsoft.Json so that will need to be included in your project unless you want to change/customize the de-serialization method!

FakeAgent.cs: https://pastebin.com/fsSzTGf2 | (Raw) https://pastebin.com/raw/fsSzTGf2
agent_list.json: https://pastebin.com/NRvZQ1Bj | (Raw) https://pastebin.com/raw/NRvZQ1Bj


Usage:

Code

FakeAgent agent = new FakeAgent();
for (int i = 0; i < 10; i++)
    WriteLog("Random agent: {0}", agent.New.Random().AgentString);
for (int i = 0; i < 10; i++)
    WriteLog("Random iOS agent: {0}", agent.New.OSType("iOS").Random().AgentString);
for (int i = 0; i < 10; i++)
    WriteLog("Random Console agent: {0}", agent.New.DeviceType("Console").Random().AgentString);
for (int i = 0; i < 10; i++)
    WriteLog("Random browser/windows/desktop agent: {0}", agent.New.AgentType("Browser").OSType("Windows").DeviceType("Desktop").Random().AgentString);
for (int i = 0; i < 10; i++)
    WriteLog("Random crawler agent: {0}", agent.New.AgentType("Crawler").Random().AgentString);

Credits to the guy on github who made a user agent list generator in PHP. I just took the agent_list and modified it for C# use: https://github.com/joecampo/random-user-..._list.json

If you have any questions / suggestions, feel free to let me know. But please do a little research first if it's something basic like adding resources or new classes to a project.

The property in the fake agent class confuses me. First you create an array, then copy a list to that array, then convert the array to a list. Why?

I think his end goal was to have a copy of the list of agents to prevent InvalidOperation exceptions on the filtering/random methods. Returning the ToList is enough.

The Skip in the Random method is weird to me. Easier to return the item at the index instead of skipping. It's also not thread safe.

I was messing around with it a lot and was modifying the collection at one point. Now that it's not being modified the copy doesn't really need to be there.

Good point, should just directly access agentList[random.Next(agentList.Count())]

Don't forget about making it thread safe. If you remove that "New" property, all the other methods aren't thread safe either.

You mentioned only needing to use ToList instead of the array copy -- does ToList() return a new object unlinked from the original list? I find myself getting hooked on references a lot when dealing with IEnumerables/Lists.

The List will be a new object, but the items inside will still have the references to the old objects.

[0xDEAD10CC]

This isn't very well designed...

To solve that references issue - you could create a new list with the capacity of the count of the first (prevent reallocation), and return the new List<T> to return. Add them to the list, no need for an array. Create your own Clone() method (not implemented from ICloneable), and return the type rather than object as another more abstract solution that lets the implementation define how the copy should take place and whether it's a shallow or deep copy.

---

Code

public interface ICloneable<out T>
{
    T Clone();
}

private class Obj : ICloneable<Obj>
{
    public int Value { get; set; }

    public Obj(int value)
    {
        Value = value;
    }

    public Obj Clone()
    {
        return new Obj(Value);
    }

    public override string ToString()
    {
        return $"{Value}";
    }
}

public static void Main(string[] args)
{
    List<Obj> list1 = new List<Obj>
    {
        new Obj(1),
        new Obj(2),
        new Obj(3)
    };
    
    List<Obj> list2 = new List<Obj>(list1.Count);
    list1.ForEach(o => list2.Add(o.Clone()));
    list2[0].Value = 9;
    
    list1.ForEach(Console.WriteLine);
    Console.WriteLine();
    list2.ForEach(Console.WriteLine);
}

The argument against ICloneable is that there's no description of whether it provides a deep or shallow copy of the original, yet sometimes it's useful to have a clone regardless IMO, just not sure why they haven't depreciated the first yet after so long and also haven't come out with a covariant type generic ICloneable if they've kept the original interface around for so long...

Great share thanks you bro ;)

FakeAgent.cs.61 - use String.Compare() instead of calling tolower() on both strings

why are you skipping instead of accessing directly via .At() or the indexer?

What's wrong with string.Equals() for equality?

Never knew about or used .At() for some reason. Will remember that for the future.

I've ran into weird issues in the past using comparison functions, so I tend to avoid them. Also, the tolower() == tolower() is more easily read for me, and I just prefer that way of comparing.

It's not about what is easier, it's about accuracy. When you start dealing with locale you're going to have major issues comparing by using ToLower() or ToUpper() before a direct comparison using the == operator. Equals has a StringComparison parameter that you should be using.

[gigajew]

Here's how I would do it. Doesn't require internet connection and doesn't contain a huge list or a JSON parser

excuse me, i meant that one.
