Использование UpdateResource в C#?

мне удалось заставить это работать в чистом C#, используя ResourceHacker и эту публикацию в качестве примера. Просто используйте обычный .ico в качестве ввода. В ResourceHacker (http://www.angusj.com/resourcehacker/) вы увидите идентификатор значка (в моем случае 1) и идентификатор языка (в моем случае 1043):

я использовал этот код:

internal class IconChanger
{

    #region IconReader
    public class Icons : List<Icon>
    {
        public byte[] ToGroupData(int startindex = 1)
        {
            using (var ms = new MemoryStream())
            using (var writer = new BinaryWriter(ms))
            {
                var i = 0;

                writer.Write((ushort)0);  //reserved, must be 0
                writer.Write((ushort)1);  // type is 1 for icons
                writer.Write((ushort)this.Count);  // number of icons in structure(1)

                foreach (var icon in this)
                {

                    writer.Write(icon.Width);
                    writer.Write(icon.Height);
                    writer.Write(icon.Colors);

                    writer.Write((byte)0); // reserved, must be 0
                    writer.Write(icon.ColorPlanes);

                    writer.Write(icon.BitsPerPixel);

                    writer.Write(icon.Size);

                    writer.Write((ushort)(startindex + i));

                    i++;

                }
                ms.Position = 0;

                return ms.ToArray();
            }
        }
    }

Это решение, которое работает для меня. Я не смог написать его в .NET, но мне удалось написать DLL C++, на которую я ссылаюсь в своем приложении c#.

C++ DLL

содержимое решения C++ я создаю DLL из:

#include <io.h>

        buffer = (char *)malloc(buffersize);
        read(hFile, buffer, buffersize);
        close(hFile);

        EndUpdateResource(hWhere, FALSE);
    }
}

C# код

Это код C#, который я использую для импорта ChangeIcon функция из ранее написанной DLL:

[DllImport("IconChanger.dll")]
static extern void ChangeIcon(String executableFile, String iconFile, short imageCount);

/// <summary>
/// Changes the executable's icon
/// </summary>
/// <param name="exeFilePath">Path to executable file</param>
/// <param name="iconFilePath">Path to icon file</param>
static public void ChangeIcon(string exeFilePath, string iconFilePath)
{
    short imageCount = 0;

    using (StreamReader sReader = new StreamReader(iconFilePath))
    {
        using (BinaryReader bReader = new BinaryReader(sReader.BaseStream))
        {
            // Retrieve icon count inside icon file
            bReader.ReadInt16();
            bReader.ReadInt16();
            imageCount = bReader.ReadInt16();
        }
    }

    // Change the executable's icon
    ChangeIcon(exeFilePath, iconFilePath, imageCount);
}

надеюсь, по крайней мере, кто-то найдет это полезным.

для типа или имени строкового ресурса вы просто передаете строку. Для системных предопределенных типов, таких как RT_ICON и идентификаторы int, такие как IDI_APPLICATION, вы передаете это целое значение reinterpret-приведение его к указателю, например (char*)3 на RT_ICON.
