hi,

\r\n

 

\r\n

i have a little problem with the embedding in c# (c#newbie)

\r\n

 

\r\n

my code..

\r\n

 

\r\n

\r\n

\r\n
using System;\r\nusing System.Collections.Generic;\r\nusing System.Linq;\r\nusing System.Text;\r\nusing System.Reflection;\r\nusing System.IO;\r\n\r\nnamespace Test
{\r\n    class WebifyChmForm\r\n    {\r\n        static WebifyChmForm()  \r\n        {\r\n            AppDomain.CurrentDomain.AssemblyResolve += new ResolveEventHandler(Resolver);\r\n        }\r\n\r\n        static System.Reflection.Assembly Resolver(object sender, ResolveEventArgs args)\r\n        {\r\n            Assembly a1 = Assembly.GetExecutingAssembly();\r\n            Stream s = a1.GetManifestResourceStream("Ionic.Zip.dll");\r\n            byte[] block = new byte[s.Length];\r\n            s.Read(block, 0, block.Length);\r\n            Assembly a2 = Assembly.Load(block);\r\n            return a2;\r\n        }\r\n\r\n    }\r\n}\r\n

code in form1 from button


 private void button1_Click(object sender, EventArgs e)\r\n        {\r\n\r\n\r\n            using (ZipFile zip = new ZipFile())\r\n            {\r\n                \r\n                zip.AddFile("test.png");\r\n                zip.AddFile("test1.png");\r\n                zip.Save("myzip.zip");\r\n            }\r\n\r\n        }\r\n

here comes a error (bold)

\r\n
\r\n
\r\n
\r\n

\r\n
using (ZipFile zip = new ZipFile())

error: The  type or namespace name "ZipFile" could not be found. (Missing a  using directive or an assembly reference?)

why not this work?


sorry for my bad english..

How did you embed the DotNetZip assembly into your EXE?

\r\n

Depending on how you did that, the name of the embedded stream will vary.  It could have the name of your Visual studio project in it:  MyProject1.Ionic.Zip.dll . Or it might not.

\r\n

You can check the names of resources in your assembly by using this kind of code:

\r\n
\r\n
        public void Run()\r\n        {\r\n            var tAssembly = Assembly.LoadFrom(_assemblyName);\r\n\r\n            string[] resourceNames = tAssembly.GetManifestResourceNames();\r\n            if (resourceNames != null && resourceNames.Length > 0)\r\n            {\r\n\r\n                foreach(string resourceName in resourceNames)\r\n                {\r\n                    System.Console.WriteLine(resourceName);\r\n                }\r\n            }\r\n            else\r\n            {\r\n                System.Console.WriteLine("-none-");\r\n            }\r\n        }\r\n\r\n
\r\n
\r\n

I've written a simple tool that can do this for you, for any .NET assembly. It's available for download.

\r\n

it looks like this:

Hi ! I have the same problem. When I run your software, I see :  "MyProject.Ionic.Zip.dll" !  But I do not know how to compile my project without this error:

error: The  type or namespace name "ZipFile" could not be found. (Missing a  using directive or an assembly reference?)

\r\n

I have a warning message :
Unable to apply the advertisement properties for the element "ionic.zip.dll.MyProject"

\r\n

Could you please make a small project (console or window) to compress a file using the included DLL file ?

\r\n

Thanking you in anticipation !

\r\n

 

\r\n

It's an example of my project :

\r\n
\r\n
using System;\r\nusing System.Collections.Generic;\r\nusing System.Linq;\r\nusing System.Text;\r\nusing System.Reflection;\r\n//using Ionic.Zip;\r\nusing System.IO;\r\n\r\nnamespace ConsoleApplication1\r\n{\r\n    class Program\r\n    {\r\n\r\n        // static constructor to add a handler to the AssemblyResolve event \r\n        static Program()  //   <--- this must be the name of your main class\r\n        {\r\n            AppDomain.CurrentDomain.AssemblyResolve += new ResolveEventHandler(Resolver);\r\n        }\r\n\r\n        static System.Reflection.Assembly Resolver(object sender, ResolveEventArgs args)\r\n        {\r\n            Assembly a1 = Assembly.GetExecutingAssembly();\r\n            System.IO.Stream s = a1.GetManifestResourceStream("Ionic.Zip.dll");\r\n            byte[] block = new byte[s.Length];\r\n            s.Read(block, 0, block.Length);\r\n            Assembly a2 = Assembly.Load(block);\r\n            return a2;\r\n        }\r\n\r\n\r\n        static void Main(string[] args)\r\n        {\r\n            System.Console.WriteLine("Compressing ...");

I think you are trying to do the same thing, or a similar thing, which is to embed the dll into your exe, but i don't think you are having the same problem. \r\n

\r\nI think you have a more basic problem: The ZipFile type is not known to the compiler. The first question, is, of course, why did you comment out the namespace declaration at the top of your source code? The line that reads "using Ionic.Zip" is the line that declares the ZipFile type (as well as all the others in the Ionic.Zip namespace) to the compiler. If you comment out that line, you will get unknown type errors at compile time. \r\n

\r\n\r\nI think the error message you posted must be a translation, because it doesn't sound familiar to me. But I'm pretty sure you need to include the namespace declaration in order to successfully compile. Embedding the dll allows you to avoid distributing the dll separately at runtime; it does not change the compile-time requirements for namespace declaration, and assembly references.\r\n

\r\nGood luck.\r\n", "PostedDate": "2010-10-05T05:10:49.407-07:00", "UserRole": null, "MarkedAsAnswerDate": null }, { "Id": "502564", "ThreadId": "205567", "Html": "

Hi,

\r\n


Thank you for your response and your time given to my problem.

\r\n

So, yes I translated my error generated by Visual Studio, it was a temporary warning message.As the title of this post, I try to embed the DLL in my project but I can not.
As the example above,  there haven't  "using Ionic.Zip", so I put the line a comment. Now I understand that it is important to put this line for compiler.

I give you my source file if you have time to find and solve my problem, I'd be very grateful for some help.

I made a class file that you can copy paste into your project and use it to call the basic Zip and Unzip Methods using the Ionic.Zip.Reduced.dll. 

\r\n

All that is needed is that you include Ionic.Zip.Reduced.dll into your project and you set it as an embedded resource.  Then just add this code into your project.

\r\n

And from your calling class, you can just call ZIPPER.CreateZipFile(zipfileName, datafileName) and ZIPPER.UnzipFile(zipfilename, unzipFileLocation).  If you need

\r\n

any other methods from the DLL, you should be able to follow the code fairly easily (it's commented) to implement whatever methods you were looking for.
