embed an executable (or any other file) into your application in C# (转载)

C# Source Code: embed_executable_source.zip

 Sometimes it is necessary to embed an executable (or any other file) into your application
        and later recreate it during runtime. At the center of the technique are the Resource capabilities
        of .NET and the concept of Reflection. Below is an example of such a technique using C#.
        Steps in 'plain' English
        1. Embed executables using Visual Studio IDE.
        2. Use Reflection to investigate current assembly for all embedded resources.
        3. For desired Resource(s), open a Stream to the Resource.
        4. Read from this Stream and simultaneously write the contents of Stream to disk.

Sample Source Code

//======================================================
        //Recreate all executable resources
        //======================================================
        private void mRecreateAllExecutableResources() {
            // Get Current Assembly refrence
            Assembly currentAssembly = Assembly.GetExecutingAssembly();
            // Get all imbedded resources
            string[] arrResources = currentAssembly.GetManifestResourceNames();

            foreach (string resourceName in arrResources) {
                if (resourceName.EndsWith(".exe")) { //or other extension desired
                    //Name of the file saved on disk
                    string saveAsName = resourceName;
                    FileInfo fileInfoOutputFile = new FileInfo(saveAsName);
   //CHECK IF FILE EXISTS AND DO SOMETHING DEPENDING ON YOUR NEEDS
                    if (fileInfoOutputFile.Exists) {
                        //overwrite if desired (depending on your needs)
                        //fileInfoOutputFile.Delete();
                    }
                    //OPEN NEWLY CREATING FILE FOR WRITTING
                    FileStream streamToOutputFile = fileInfoOutputFile.OpenWrite();
                    //GET THE STREAM TO THE RESOURCES
                    Stream streamToResourceFile =
currentAssembly.GetManifestResourceStream(resourceName);

                    //---------------------------------
                    //SAVE TO DISK OPERATION
                    //---------------------------------
                    const int size = 4096;
                    byte[] bytes = new byte[4096];
                    int numBytes;
                    while ((numBytes = streamToResourceFile.Read(bytes, 0, size)) > 0) {
                        streamToOutputFile.Write(bytes, 0, numBytes);
                    }

                    streamToOutputFile.Close();
                    streamToResourceFile.Close();
                }//end_if

            }//end_foreach
        }//end_mRecreateAllExecutableResources

 Each individual file must be added into your solution as an Embedded Resource? To do this right
        click in the Solution Explorer then select:  Add-> Existing Item. Now locate the executable (or any other)
        file of your choice and then select it. You will now see this file in the Solution Explorer. Now right
        click on it and choose Properties-> Make sure "Build Action" has "Embedded Resource" selected.
