I'm currently working on a project which has to run on mono.
Normally, everything works just fine. But when I try to run it in a separate screen on my ubuntu 14.04 server, it won't start after crashing once. The error that occurs is the following:
System.UriFormatException: Invalid URI: The URI scheme is not valid.

at Project.Server.Settings..ctor () <0x4013c1f0 + 0x0006f> in <filename unknown>:0
This seems very strange to me, as the code that produces the error is the following:
private XDocument configFile;
public Settings()
{
var readerSettings = new XmlReaderSettings { CheckCharacters = false };
using (var reader = XmlReader.Create("config.xml", readerSettings))
{
configFile = XDocument.Load(reader);
}
}
As mentioned before, everything works just fine when run the first time. But after it crashed once, it won't start and crashes with this error. More strangely, I can fix the problem by terminating the screen and making a new one and running the exact same command.
Has anybody encountered something like this before? Is this something that can be prevented?

I'm trying to use the Raspberry Sharp IO library to write to a pin on the Pi. But it gives me an exception on runtime. It had worked before, but doesnt any more. Why is this error being thrown?
using System;
using Raspberry.IO.GeneralPurpose;
using Raspberry.IO.GeneralPurpose.Behaviors;
using System.Threading;
namespace blinky
{
class MainClass
{
public static void Main (string[] args)
{
// Here we create a variable to address a specific pin for output
// There are two different ways of numbering pins--the physical numbering, and the CPU number
// "P1Pinxx" refers to the physical numbering, and ranges from P1Pin01-P1Pin40
var led1 = ConnectorPin.P1Pin03.Output();
// Here we create a connection to the pin we instantiated above
var connection = new GpioConnection(led1);
while(true){
// Toggle() switches the high/low (on/off) status of the pin
connection.Toggle(led1);
Thread.Sleep(250);
}
// connection.Close();
}
}
}
returns this error:
pi#Minion01 ~/blinky1/blinky1/bin/Debug $ mono ./blinky1.exe

How may i fix it?
I had tried to run this through monodevelop on the pi and also using mono filename.exe . Neither worked. But it did when I used sudo ./filename.exe.
I had to change the auth system behind the Google Analytics API following the old auth system becoming defunct. As a result of a SO post, my auth file went from:
protected override void Load(ContainerBuilder builder)
{
builder.Register(c =>
{
var service = new AnalyticsService("mrfreeman.com");
service.setUserCredentials("robot#mrfreeman.com", "jellyfish");
return service;
});
builder.RegisterType<AnalyticsNewsletterTrackingSource>().As<INewsletterTrackingSource>();
builder.RegisterType<AnalyticsSearchTrackingSource>().As<ISearchTrackingSource>();
builder.RegisterType<AnalyticsEmailLinkTracker>().As<IEmailLinkTracker>();
}
To:
private const string ServiceAccountEmail = "blabla#developer.gserviceaccount.com";
private static readonly string KeyPath = System.IO.Path.Combine(AppDomain.CurrentDomain.SetupInformation.PrivateBinPath ?? AppDomain.CurrentDomain.BaseDirectory, "Key.p12");
private static readonly X509Certificate2 Certificate = new X509Certificate2(KeyPath, "notasecret", X509KeyStorageFlags.Exportable);
private readonly ServiceAccountCredential _credential = new ServiceAccountCredential(
new ServiceAccountCredential.Initializer(ServiceAccountEmail)
{
Scopes = new[] { "https://www.googleapis.com/auth/analytics" }
}.FromCertificate(Certificate));
protected override void Load(ContainerBuilder builder)
{
builder.Register(c =>
{
_credential.RequestAccessTokenAsync(System.Threading.CancellationToken.None).Wait();
var service = new AnalyticsService("mrfreeman.com");
var requestFactory = new GDataRequestFactory("shazbot2.0");
requestFactory.CustomHeaders.Add(string.Format("Authorization: Bearer {0}", _credential.Token.AccessToken));
service.RequestFactory = requestFactory;
return service;
});
builder.RegisterType<AnalyticsNewsletterTrackingSource>().As<INewsletterTrackingSource>();
builder.RegisterType<AnalyticsSearchTrackingSource>().As<ISearchTrackingSource>();
builder.RegisterType<AnalyticsEmailLinkTracker>().As<IEmailLinkTracker>();
}
Doing all the necessary boiler plate of copying the generated developer email address and P12 key into the project.
The problem is this: It works on Windows but throws problems with the services running on mono and are dependant on the Analytics module. Currently using 4.0.2 version of Mono.
What I've tried:
Using old and new versions of mono - 3.10 and 4.2.0 pre-release to run the service (which is itself built by Visual Studio) and check if exception is produced.
Import System.Net.Http and copy to local (currently not referenced in service) - still produces same exception
At this stage I'm cornered into learning the new Google Analytics API and re-writing everything from scratch as I tried to use the old API but update the Auth API with little luck, but feel this a blunt-instrument type solution.
The stack trace is the same on any version and is:

I was having similar issue, So thought try removing and adding the following DLLS to fix it.
Removed System.net.http, OkHttp, ModernClient. Found the issue was with ModernClientHttp and OkHttp dlls added under references.
I have removed OkHttp and ModernClientHttp and added the ModernClientHttp via Nuget and that works for me.
Give a try if that helps.
I'm using Aspose.Words to convert a doc/docx file to a pdf file on ubuntu. Mono runtime has been installed. My code is below:
Document doc = new Document ("/data/upfile/test.docx");
doc.Save ("/data/upfile/test.pdf", SaveFormat.Pdf);
Somehow, when the second line of the code is executed, an error was thrown. The detail is below:

Often inner exceptions is a very common problem for converting words documents in PDF via Aspose.
It can be due to some reasones like:
2013 MS Word office.
Some complex elements in word
Old version of Aspose.Words.dll.
Solutions:
Try to update Aspose.Words.dll to new version. If it's still not working - write to aspose forum, and this error will be fixed in new release.
Check word document itself. may be you can find something thac call this inner exception, than try to remove it and check again. If this is acceptable of course.
I am trying to get the demo from http://www.mono-project.com/MySQL working on Ubuntu 11.10, using Mono 2.10.5.
Installed MySQL v2 drivers (after renaming) to the gac. Added provider a line to the machine.config.
Hello World demo compiles and runs fine. The following code executes and connects on MSVS fine.
The compile cmd works: mcs TestMysqlConnect.cs -r:System.Data.dll -r:/home/steve/MONO/Assemblies/Mysql/v2/MySql.Data.dll
using System;
using System.Data;
using MySql.Data.MySqlClient;
public class Test
{
public static void Main(string[] args)
{
string connectionString =
"Server=192.168.111.4;" +
"Database=LOADTRACKER;" +
"Port=3306;" +
"User ID=oec;" +
"Password=oec;" +
"Pooling=false";
Console.WriteLine("Create MySqlConnection");
IDbConnection dbcon;
dbcon = new MySqlConnection(connectionString);
Console.WriteLine("dbcon.Open();");
dbcon.Open();
IDbCommand dbcmd = dbcon.CreateCommand();
Console.WriteLine("dbcon.CreateCommand();");
// requires a table to be created named employee
// with columns firstname and lastname
// such as,
// CREATE TABLE employee (
// firstname varchar(32),
// lastname varchar(32));
string sql =
"SELECT Account, Security " +
"FROM accesslist";
dbcmd.CommandText = sql;
IDataReader reader = dbcmd.ExecuteReader();
while(reader.Read()) {
string acct = (string) reader["Account"];
string sec = (string) reader["Security"];
Console.WriteLine("Acct: " + acct + " (" + sec + ")");
}
// clean up
reader.Close();
reader = null;
dbcmd.Dispose();
dbcmd = null;
dbcon.Close();
dbcon = null;
}
}
Executing this code produces:
$mono ./TestMysqlConnect.exe
Create MySqlConnection
dbcon.Open();
Unhandled Exception: System.OverflowException: Number overflow.

Interestingly, if I provide a bad user/password, I get the expected exception of:
[ERROR] FATAL UNHANDLED EXCEPTION: MySql.Data.MySqlClient.MySqlException: Authentication to host '192.168.111.4' for user 'root' using method 'mysql_native_password' failed with message: Access denied for user 'root'#'linux' (using password: YES) ---> MySql.Data.MySqlClient.MySqlException: Access denied for user 'root'#'linux' (using password: YES)
Any help is greatly appreciated. Thank you.
I need to parse XML string with Linq, and I came up with the following code.
using System;
using System.Linq;
using System.Xml.Linq;
class LinqXml
{
public void Parse(string input)
{
XDocument xdoc = XDocument.Load(input);
var lang = from d in xdoc.Elements("PipeUnit").Elements("Step").Elements("Pipelist").Elements("NamedPipe").Elements("NameOfPipe") select d;
Console.WriteLine(lang.First().Value);
foreach (var item in lang)
{
Console.WriteLine(item.Value);
}
}
static void Main()
{
string tempString = #"
<PipeUnit>
<Step>
<Pipelist>
<NamedPipe>
<NameOfPipe>Name</NameOfPipe>
<PipeData>Data</PipeData>
</NamedPipe>
</Pipelist>
</Step>
</PipeUnit>
";
var linqXml = new LinqXml();
linqXml.Parse(tempString);
}
}
When compile this code with Mono - dmcs linqxml.cs /r:System.Xml.Linq.dll, and tried to run, I got the following errors.
Unhandled Exception: System.IO.DirectoryNotFoundException: Could not find a part of the path "/Users/smcho/Desktop/csharp/

</NamedPipe>
</Pipelist>
</Step>

What might be wrong?
Replace this:
XDocument xdoc = XDocument.Load(input);
with:
XDocument xdoc = XDocument.Parse(input);
you are passing XML, not a file name.
in your Parse method, you want
XDocument.Parse(input)
Replace
XDocument xdoc = XDocument.Load(input);
with
XDocument xdoc = XDocument.Parse(input);
