همانطور که در تصویر بالا نیز مشاهده می‌کنید، اسمبلی‌های ارجاعی برنامه TestApp به صورت Resource به آن اضافه شده‌اند.

نحوه بارگذاری اسمبلی‌های Embed شده

در پروژه‌های WPF، در OnStartup event کلاس App و در پروژه‌های WinForm در متد Main کلاس Program، قطعه کد زیر را وارد می‌کنیم:

private void App_OnStartup( object sender, StartupEventArgs e )
{
    AppDomain.CurrentDomain.AssemblyResolve += OnResolveAssembly;
    var assembly = Assembly.GetExecutingAssembly();
    foreach (var name in assembly.GetManifestResourceNames())
    {
        if ( name.ToLower()
                 .EndsWith( ".resources" ) ||
             !name.ToLower()
                  .EndsWith( ".dll" ) )
            continue;
        EmbeddedAssembly.Load( name,
                               name );
    }
}

static Assembly OnResolveAssembly( object sender, ResolveEventArgs args )
{
    var fields = args.Name.Split( ',' );
    var name = fields[0];
    var culture = fields[2];
    if ( name.EndsWith( ".resources" ) &&
         !culture.EndsWith( "neutral" ) )
        return null;

    return EmbeddedAssembly.Get( args.Name );
}

با استفاده از رویداد AssemblyResolve می توان اسمبلی Embed شده را در زمانیکه نیاز به آن است، بارگذاری کرد. کد مربوط به کلاس EmbeddedAssembly نیز به این صورت می‌باشد:

using System;
using System.Collections.Generic;
using System.IO;
using System.Reflection;
using System.Security.Cryptography;

public static class EmbeddedAssembly
{
    static Dictionary< string, Assembly > _dic;

    public static void Load( string embeddedResource,
                                string fileName )
    {
        if ( _dic == null )
            _dic = new Dictionary< string, Assembly >();

        byte[] ba;
        Assembly asm;
        var curAsm = Assembly.GetExecutingAssembly();

        using ( var stm = curAsm.GetManifestResourceStream( embeddedResource ) )
        {
            if ( stm == null )
                return;

            ba = new byte[(int)stm.Length];
            stm.Read( ba,
                      0,
                      (int)stm.Length );
            try
            {
                asm = Assembly.Load( ba );

                _dic.Add( asm.GetName().Name,
                            asm );
                return;
            }
            catch
            {
            }
        }

        bool fileOk;
        string tempFile;

        using ( var sha1 = new SHA1CryptoServiceProvider() )
        {
            var fileHash = BitConverter.ToString( sha1.ComputeHash( ba ) )
                                        .Replace( "-",
                                                    string.Empty );

            tempFile = Path.GetTempPath() + fileName;

            if ( File.Exists( tempFile ) )
            {
                var bb = File.ReadAllBytes( tempFile );
                var fileHash2 = BitConverter.ToString( sha1.ComputeHash( bb ) )
                                            .Replace( "-",
                                                        string.Empty );

                fileOk = fileHash == fileHash2;
            }
            else
            {
                fileOk = false;
            }
        }

        if ( !fileOk )
        {
            File.WriteAllBytes( tempFile,
                                ba );
        }

        asm = Assembly.LoadFile( tempFile );

        _dic.Add( asm.GetName().Name,
                    asm );
    }

    public static Assembly Get( string assemblyFullName )
    {
        if ( _dic == null ||
                _dic.Count == 0 )
            return null;

        var name = new AssemblyName( assemblyFullName ).Name;
        return _dic.ContainsKey( name )
            ? _dic[name]
            : null;
    }
}

با استفاده از متد Load کلاس بالا، کل اسمبلی‌هایی که بارگذاری شده‌اند در یک دیکشنری استاتیک نگهداری می‌شوند. ابتدا اسمبلی‌ها را با استفاده از []byte بارگذاری می‌کنیم و در صورتیکه بارگذاری اسمبلی با خطایی مواجه شود، بارگذاری را با استفاده از فایل temp انجام می‌دهیم (که معمولا برای فایل‌های unmanaged این مورد اتفاق می‌افتد).

با استفاده از متد Get که در زمان نیاز به یک اسمبلی توسط AssemblyResolve فراخوانی می‌شود، اسمبلی مربوطه از دیکشنری پیدا شده و برگشت داده می‌شود.

نکته ها

• در صورتیکه بخواهید فایلی را از Embed کردن خودکار (روش دوم) استثناء کنید، باید از Condition استفاده کنید:

  <Target Name="EmbedReferencedAssemblies" AfterTargets="ResolveAssemblyReferences">
    <ItemGroup>
      <AssembliesToEmbed Include="@(ReferenceCopyLocalPaths)" />
      <EmbeddedResource Include="@(AssembliesToEmbed)" Condition="$([System.Text.RegularExpressions.Regex]::IsMatch('%(AssembliesToEmbed.Filename)', '^((?!Microsoft).)*$')) And '%(AssembliesToEmbed.Extension)' == '.dll'">
        <LogicalName>%(AssembliesToEmbed.DestinationSubDirectory)%(AssembliesToEmbed.Filename)%(AssembliesToEmbed.Extension)</LogicalName>
      </EmbeddedResource>
    </ItemGroup>
    <Message Importance="high" Text="Embedding: @(AssembliesToEmbed->'%(DestinationSubDirectory)%(Filename)%(Extension)', ', ')" />
  </Target>
  <Target Name="DeleteAllReferenceCopyLocalPaths" AfterTargets="Build">
    <Delete Files="@(ReferenceCopyLocalPaths->'$(OutDir)%(DestinationSubDirectory)%(Filename)%(Extension)')" Condition="$([System.Text.RegularExpressions.Regex]::IsMatch('%(Filename)', '^((?!Microsoft).)*$')) Or '%(Extension)' == '.xml'" />
  </Target>

[assembly: NeutralResourcesLanguage("en-US", UltimateResourceFallbackLocation.MainAssembly)]

• در صورتیکه پروژه شما از نوع Office Add-Ins باشد، باید در کد مربوط به AssemblyResolve را در فایل ThisAddIn.Designer.cs (در صورت عدم تغییر نام) به متد Initialize اضافه کنید و دستور بارگذاری را در متد ThisAddIn_Startup اضافه کنید. نکته خیلی مهم:  در فایل csproj حتما در قسمت Condition باید اسمبلی‌هایی را که با نام Microsoft شروع می‌شوند، از Embed شدن استثناء کنید و در قسمت DeleteAllReferenceCopyLocalPaths مقدار "AfterTargets="VisualStudioForApplicationsBuild را قرار دهید (تا امکان Build پروژه برای شما باشد) و همچنین پسوند vsto را نیز نباید حذف کنید.
