Invalid URI: The hostname could not be parsed.

I am getting this error when calling mailchimpManager.List.GetAllAsync() and this is the stacktrace:

at System.Uri.CreateThis(String uri, Boolean dontEscape, UriKind uriKind)
at System.Uri..ctor(String uriString)
at MailChimp.Net.Core.BaseLogic.CreateMailClient(String resource)
at MailChimp.Net.Logic.ListLogic.d__4.MoveNext()
--- End of stack trace from previous location where exception was thrown ---

at System.Runtime.CompilerServices.ConfiguredTaskAwaitable`1.ConfiguredTaskAwaiter.GetResult()
at MailChimp.Net.Logic.ListLogic.d__3.MoveNext()

Anyone have an idea of what I might be doing wrong? I have never come across this error and Google searching hasn't turned up anything useful.

I had the same issue I solved by setting the app key after the instantiating call.

MC = new MailChimpManager();
MC.Configure(new MailChimpConfiguration{ApiKey = apkey});

Hmmm, I attempted your fix but I still got the same error. Here's the code before:

MailChimp.Net.MailChimpManager mcUHFManager = new MailChimp.Net.MailChimpManager(mcUHFAPIKey);
mcUHFManager.Configure(new MailChimp.Net.MailChimpConfiguration { Limit = 100 });
MailChimp.Net.MailChimpManager mcAGManager = new MailChimp.Net.MailChimpManager(mcAGAPIKey);
mcAGManager.Configure(new MailChimp.Net.MailChimpConfiguration { Limit = 100 });

try
{
	viewModel.mailChimpLists = mcUHFManager.Lists.GetAllAsync().Result;
}
catch (Exception excep)
{
	throw;
}

and here's the code after your fix:

MailChimp.Net.MailChimpManager mcUHFManager = new MailChimp.Net.MailChimpManager();
mcUHFManager.Configure(new MailChimp.Net.MailChimpConfiguration { ApiKey = mcUHFAPIKey });
mcUHFManager.Configure(new MailChimp.Net.MailChimpConfiguration { Limit = 100 });
MailChimp.Net.MailChimpManager mcAGManager = new MailChimp.Net.MailChimpManager();
mcAGManager.Configure(new MailChimp.Net.MailChimpConfiguration { ApiKey = mcAGAPIKey });
mcAGManager.Configure(new MailChimp.Net.MailChimpConfiguration { Limit = 100 });

try
{
	viewModel.mailChimpLists = mcUHFManager.Lists.GetAllAsync().Result;
}
catch (Exception excep)
{
	throw;
}

both ways are caught in the try/catch with the same Invalid URI error.

Also having trouble with this, any further clarification would be super helpful.

Thanks!

Please check in your branch into your public repos so we can help.

[spyguyhi]

Branch? I haven't changed your code at all but rather added your api through nuget in our application.

Latest news. We were finally able to obtain VS 2017 where previously we used VS2013 so weren't able to compile the wrapper project. I then removed the wrapper reference installed through Nuget and compiled and manually added the wrappers dll. I no longer get this error. I don't know if its because I downloaded the code September last year or if it is because our project is now able run the newer C# code.

It is because you are reconfiguring mailchimp please provide the limit and API key in the same instance of MailChimpConfiguration
