I cant get SevenZipLib library to work (p/invoke)

Very basic knowledge on c# and is the first i use anything p/invoke related.
Help me pls, i have made this code but it doesnt seem to work.
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using System.Runtime.InteropServices;
namespace WindowsFormsApplication3
{
public partial class Form1 : Form
{
[DllImport("C:\\Users\\lchris\\Desktop\\SevenZipLib_9.13.2\\SevenZipLib\\SevenZipLib\\7z86.dll")]
public static extern void SevenZipArchive(string c);
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
using (SevenZipArchive archive = new SevenZipArchive("file.rar"))
{
foreach (ArchiveEntry entry in archive)
{
Console.WriteLine(entry.FileName);
}
}
}
}
}
It tells me that SevenZipArchive is a 'Method' and is being used like a 'type'.
I have include the library to my project already, i just dont know how to use it.
Here is the library:
https://sevenziplib.codeplex.com/

You first need to remove this code:
[DllImport("...")]
public static extern void SevenZipArchive(string c);
You do not need to provide any p/invoke declarations. The library wraps that up for you.
This is a .net assembly. You use it just as you use any other. Take the following steps:
Download the project. You already did that I think.
Build the solution. Make sure that
In your project, add a reference to the assembly that you built in the previous stage. It's SevenZipLib\bin\Debug\SevenZipLib.dll or SevenZipLib\bin\Release\SevenZipLib.dll depending on the target you selected.
Add using SevenZipLib; to your project code to to gain access to the namespace.
Once you've done that your code will work. You can use the tests project that is supplied as part of the download as a rich source of example code.

Sikuli Integrator C#

I want to use SikuliIntegrator in C#.
I run VS as administrator, install SikuliIntegrator throught NuGet manager and want to test him on simple task.
Heres my code
using SikuliModule;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace SikuliTrainingNet
{
class Program
{
static void Main(string[] args)
{
string MyPicture = #"c:\111\Sik\MyPicture.png";
SikuliAction.Click(MyPicture);
}
}
}
after running code (and have prepared MyPicture on screen), all i get is exception "###FAILURE" any idea why?
I dont wanna use Sikuli4Net, becose its look like it work on web aps and I need just few simple clicks on desktop aplication.
I try sikuli in Java, and there it works with no problem. But I need to make my program in C#.

I Used This Code For Sikuli4Net in C#,It Was Working For Me First You need add the References please see this link for Reference
http://interviews.ga/angularjs/sikulic/
static void Main(string[] args)
{
APILauncher launch = new APILauncher(true);
Pattern image1 = new Pattern(#"C:\Users\Ramesh\Desktop\Images\userName.png");
Pattern image2 = new Pattern(#"C:\Users\Ramesh\Desktop\Images\password.png");
Pattern image3 = new Pattern(#"C:\Users\Ramesh\Desktop\Images\Login.png");
launch.Start();
IWebDriver driver = new ChromeDriver();
driver.Manage().Window.Maximize();
driver.Url = "http://gmail.com";
Screen scr = new Screen();
scr.Type(image1, "abc#gmail.com", KeyModifier.NONE);
scr.Type(image2, "12345", KeyModifier.NONE);
scr.Click(image3, true);
Console.ReadLine();
}

I used this code and it was working fine. First you should open the webpage on which you want to click and then give a path of the image(it should be a part of the webpage)
here is my code:
using System;
using System.Collections.Generic;
using System.Drawing;
using System.Linq;
using Microsoft.VisualStudio.TestTools.UnitTesting;
using SikuliModule;
using OpenQA.Selenium;
namespace WordPressAutomation.DifferentTests
{
[TestClass]
public class Sikuli
{
[TestMethod]
public void TestMethod1()
{
driver.Initialize();
driver.instance.Navigate().GoToUrl("https://www.google.co.in");
SikuliAction.Click("E:/img.png");
}
}
}

To use SikuliInyegrator, you need to check the execution results in these files:
C:\SikuliExceptionLog.txt
C:\SikuliOutputLog.txt
Also you need to:
Have installed JRE7 or superior
Have environment variable PATH with the location of the bin folder
See installed in your “control panel > program and features> visual C++ 2010 Redistributable Package” at x86 and x64 bits according to your java JRE runtime platform. If not, then download and install the Redistributable Package form Microsoft site.

C# "await" error when using WinRT from Desktop app

I trying to get my GPS position from a Desktop app, using Windows Runtime, in C#.
I followed this how-to to set up Visual Studio and this code sample to create the following trivial code as a C# console app :
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading;
using System.Threading.Tasks;
using System.IO;
using System.Runtime;
using System.Windows;
using Windows;
using Windows.Devices.Geolocation;
using Windows.Foundation;
using Windows.Foundation.Collections;
namespace GeoLocCS
{
public sealed partial class Program
{
static void Main(string[] args)
{
Test test = new Test();
Console.Read();
}
}
public class Test
{
private Geolocator geolocator;
public Test()
{
Console.WriteLine("test");
geolocator = new Geolocator();
this.getPos();
}
async void getPos()
{
Geoposition pos = await geolocator.GetGeopositionAsync();
Console.WriteLine(pos.Coordinate.Latitude.ToString());
}
}
}
When trying to compile, I get the error :
Error 1 'await' requires that the type 'Windows.Foundation.IAsyncOperation<Windows.Devices.Geolocation.Geoposition>' have a suitable GetAwaiter method. Are you missing a using directive for 'System'?
I tried to reference every DLL that I could, like "System.runtime", "System.Runtime.WindowsRuntime", "Windows.Foundation"...
What I am missing ?
Thanks for the answer,
Serge

I finally figured out my problem :
I am on 8.1 so I changed this in the .csproj file (targetingPlatform) instead of targeting 8.0
After that modification, I could reference "Windows"
I manually referenced the two following DLLs :
C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework.NETFramework\v4.5\Facades\System.Runtime.dll
C:\Windows\Microsoft.NET\Framework64\v4.0.30319\System.Runtime.WindowsRuntime.dll

If you are On Win8.1 Please Use:
<TargetPlatformVersion>8.1</TargetPlatformVersion>
and not 8.0.

Adding to the existing answers:
I suddenly got this problem with a multiproject solution in WPF (still don't know why). I tried switching between TargetPlatformVersions 8.1 and 10.0, tried using the v4.5- and v4.5.1-System.Runtime.WindowsRuntime.dll, always alternating between BadImageFormatException and FileNotFoundException.
Turned out to be references in some of the app.config-files (not the .csproj-files!). Visual Studio 2017 must have added them at some point and as soon as I removed these entries, the above solutions finally worked.

how can I load values from App.config in c# using .Net Framework 4 Client Profile

I'm having difficulty getting my settings out of App.config. The research I've done so far says that I should be able to use ConfigurationManager.AppSettings (which is part of System.Configuration).
However, I can't get it to compile. And of course it doesn't like the older method (ConfigurationSettings.AppSettings) either as its obsolete.
What have I missed here?
Is it my project's Target Framework (currently set to ".Net Framework 4 Client Profile
")?
And example of my code follows:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Configuration;
namespace myNameSpace
{
class Program
{
private void LoadAppConfig()
{
string mySetting;
//This won't compile
mySetting =
System.Configuration.ConfigurationManager
.AppSettings["mySettingName"];
//This compiles but of course is obsolete, and I get that warning.
mySetting =
System.Configuration.ConfigurationSettings
.AppSettings["mySettingName"];
}
static void Main(string[] args)
{
// stuff happens
}
}
}

You need to add a reference to System.Configuration

C#: Referencing a windows shell interface

I'm pretty new to C#, I'm trying to complete a little side project I've been working on that uses a small amount of C# code to assist the development of a Windows Desktop Gadget. Basically, I'm trying to implement the IDesktopGadget interface so that I can use the RunGadget method.
Here's what I got so far from reading information about similar interfaces:
[ComImport]
[Guid("C1646BC4-F298-4F91-A204-EB2DD1709D1A")]
[InterfaceType(ComInterfaceType.InterfaceIsIUnknown)]
interface IDesktopGadget
{
uint RunGadget([MarshalAs(UnmanagedType.LPWStr)] string gadgetPath);
}
Unfortunately, I get an error when I try and create an object from it: "Cannot create an instance of the abstract class or interface 'GadgetTask.IDesktopGadget'"
Can someone point me in the right direction and maybe help me understand what I'm doing wrong at the same time?

You actually need an implementation of the DesktopGadget object in order to use the interface. MS provide a standard COM object to do it on Windows 7. You can create an instance by doing something like:
Type t = Type.GetTypeFromCLSID(new Guid("924ccc1b-6562-4c85-8657-d177925222b6"));
IDesktopGadget dg = (IDesktopGadget)Activator.CreateInstance(t);

Thanks for the guidance. For a little more straight forward help, this is what worked for me:
IDesktopGadget.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Runtime.InteropServices;
namespace GadgetActivator
{
[ComImport]
[Guid("C1646BC4-F298-4F91-A204-EB2DD1709D1A")]
[InterfaceType(ComInterfaceType.InterfaceIsIUnknown)]
interface IDesktopGadget
{
uint RunGadget([MarshalAs(UnmanagedType.LPWStr)] string gadgetPath);
}
}
Program.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace GadgetActivator
{
class Program
{
static void Main(string[] args)
{
Type t = Type.GetTypeFromCLSID(new Guid("924ccc1b-6562-4c85-8657-d177925222b6"));
IDesktopGadget dg = (IDesktopGadget)Activator.CreateInstance(t);
dg.RunGadget(#"C:\Program Files\Windows Sidebar\Gadgets\xxxxxxxxx.Gadget");
}
}
}
