使用C#exe修改其他C#exe的资源

解决了！见下文.

我有2个C#应用程序.应用程序a应该修改应用程序b的内部资源.应用程序b在执行时应该利用其(修改后的)资源执行某些操作.

我该怎么做？

这是我尝试过的：

public static void addFileToResources(string dest, string src)
{
    Assembly a_dest = Assembly.LoadFile(dest);

    using (Stream s_dest = a_dest.GetManifestResourceStream("Elevator.Properties.Resources.resources"))
    {
        using (ResourceWriter rw = new ResourceWriter(s_dest))
        {
            byte[] b_src = File.ReadAllBytes(src);
            rw.AddResource("target", b_src);
        }
    }
}

我得到一个System.ArgumentException与流是只读的.在System.Resources.ResourceWriter..ctor(Stream stream)上

编辑
由于.net资源似乎无法实现：还有其他方法吗？
我想生成一个可执行文件,并且可以处理从应用程序a执行之前给出的数据(存储在exe中),该文件可以执行.最好不必实际编译b即可为其提供数据.

为了使其变得简单一些的假设：

> a总是在b之前执行
> a仅执行一次
>这两个应用程序都是我写的

编辑-解决方案
由于无法通过资源完成此操作,因此我使用了以下解决方法：
显然,您可以将任何内容附加到exe文件中,并且该文件仍将是可执行文件,因此这是我想到的：

public class Packer : IDisposable
{
    // chosen quite arbitrarily; can be anything you'd like but should be reasonably unique
    private static byte[] MAGIC_NUMBER = { 0x44, 0x61, 0x6c, 0x65, 0x6b, 0x4c, 0x75, 0x63 };

    private Stream inStream;

    public Packer(string filename, bool openReadonly = false)
    {
        // The FileAccess.Read is necessary when I whant to read from the file that is being executed.
        // Hint: To get the path for the executing file I used:
        // System.Reflection.Assembly.GetExecutingAssembly().Location
        inStream = File.Open(filename, FileMode.Open, openReadonly ? FileAccess.Read : FileAccess.ReadWrite, openReadonly ? FileShare.Read : FileShare.None);
    }

    public byte[] ReadData(int index)
    {
        byte[] mn_buf = new byte[MAGIC_NUMBER.Length];
        byte[] len_buf = new byte[sizeof(Int32)];
        int data_len = 0;
        inStream.Seek(0, SeekOrigin.End);
        for (int i = 0; i <= index; ++i)
        {
            // Read the last few bytes
            inStream.Seek(-MAGIC_NUMBER.Length, SeekOrigin.Current);
            inStream.Read(mn_buf, 0, MAGIC_NUMBER.Length);
            inStream.Seek(-MAGIC_NUMBER.Length, SeekOrigin.Current);
            for (int j = 0; j < MAGIC_NUMBER.Length; ++j)
            {   // Check if the last bytes are equals to my MAGIC_NUMBER
                if (mn_buf[j] != MAGIC_NUMBER[j])
                {
                    throw new IndexOutOfRangeException("Not enough data.");
                }
            }
            inStream.Seek(-sizeof(Int32), SeekOrigin.Current);
            inStream.Read(len_buf, 0, sizeof(Int32));
            inStream.Seek(-sizeof(Int32), SeekOrigin.Current);
            // Read the length of the data
            data_len = BitConverter.ToInt32(len_buf, 0);
            inStream.Seek(-data_len, SeekOrigin.Current);
        }
        byte[] data = new byte[data_len];
        // Read the actual data and return it
        inStream.Read(data, 0, data_len);
        return data;
    }

    public void AddData(byte[] data)
    {
        // append it
        inStream.Seek(0, SeekOrigin.End);
        inStream.Write(data, 0, data.
        inStream.Write(BitConverter.GetBytes(data.Length), 0, sizeof(Int32));
        inStream.Write(MAGIC_NUMBER, 0, MAGIC_NUMBER.Length);
    }

    public void Dispose()
    {
        inStream.Dispose();
    }
}

如果要使用此代码段,请继续,但是请注意,如果将数据添加到文件中,则检索时索引的顺序相反：
假设您先写入数据集A,然后再写入数据集B,如果稍后再读取数据,则B将具有索引0,而A将具有索引1.

解决方法:

根据您的假设,您可以使用Mono.Cecil库更新/添加可执行文件的资源

这是使用Mono.Cecil进行资源处理的三种基本方法：

    public static void ReplaceResource(string path, string resourceName, byte[] resource)
    {
        var definition =
            AssemblyDefinition.ReadAssembly(path);

        for (var i = 0; i < definition.MainModule.Resources.Count; i++)
            if (definition.MainModule.Resources[i].Name == resourceName)
            {
                definition.MainModule.Resources.RemoveAt(i);
                break;
            }

        var er = new EmbeddedResource(resourceName, ManifestResourceAttributes.Public, resource);
        definition.MainModule.Resources.Add(er);
        definition.Write(path);
    }

    public static void AddResource(string path, string resourceName, byte[] resource)
    {
        var definition =
            AssemblyDefinition.ReadAssembly(path);

        var er = new EmbeddedResource(resourceName, ManifestResourceAttributes.Public, resource);
        definition.MainModule.Resources.Add(er);
        definition.Write(path);
    }

    public static MemoryStream GetResource(string path, string resourceName)
    {
        var definition =
            AssemblyDefinition.ReadAssembly(path);

        foreach (var resource in definition.MainModule.Resources)
            if (resource.Name == resourceName)
            {
                var embeddedResource =(EmbeddedResource) resource;
                var stream = embeddedResource.GetResourceStream();

                var bytes = new byte[stream.Length];
                stream.Read(bytes, 0, bytes.Length);

                var memStream = new MemoryStream();
                memStream.Write(bytes,0,bytes.Length);
                memStream.Position = 0;
                return memStream;
            }

        return null;
    }

您可以使用GetResource方法检索当前资源流(可写),

使用ResourceWriter,ResourceReader或ResourceEditor类,您可以读取/写入或修改当前资源或创建新资源,然后只需通过调用ReplaceResource将其放回可执行文件中,或通过调用AddResource将其添加为新的可执行文件

这是替换资源中图像的示例(通过从头开始创建新资源)：

            var ms = new MemoryStream();
            var writer = new ResourceWriter(ms);
            writer.AddResource("good_luck",new Bitmap("good_luck.png"));
            writer.Generate();   
            ReplaceResource(@"my executale.exe", "ResourceTest.Properties.Resources.resources",ms.ToArray());

您可以通过PM>获取Cecil安装包Mono.Cecil nuget.
