dll load

 

3rd Party Component  ex) DevExpress

 

.exe 실행파일 경로에 COM 이 필요로하는 dll 넣어줘야 로드 함. (WPF, MFC 동일)

 

ex)

 

DevExpress 는 관련 dll 들 Deployment Tool이용. (Ctrl + C ,V 로 dll 복사시 구동에 빠져있는 dll들이 있음. ex) Themes.~.dll )

 

 

COM.dll 은 빼고 COM.dll이 호출하는 나머지(DevExpress.dll)들만 복사

# COM.dll (EngSearch.CommonLib.dll) 복사 시 등록된 COM을 제대로 호출 못하는 상황 있음.

# Com.dll 위치에서 assemblyload

 {

     AppDomain currentDomain = AppDomain.CurrentDomain;
     currentDomain.AssemblyResolve += new ResolveEventHandler(currentDomain_AssemblyResolve);
 }

    Assembly currentDomain_AssemblyResolve(object sender, ResolveEventArgs args)
    {
        Assembly executingAssembly = Assembly.GetExecutingAssembly();

        string applicationDirectory = Path.GetDirectoryName(executingAssembly.Location);

        string[] fields = args.Name.Split(',');
        string assemblyName = fields[0];
        string assemblyCulture;
        if (fields.Length < 2)
            assemblyCulture = null;
        else
            assemblyCulture = fields[2].Substring(fields[2].IndexOf('=') + 1);

        //MessageBox.Show($"Assembly Name: {assemblyName}, Culture: {assemblyCulture}", "Assembly Resolve");

        string assemblyFileName = assemblyName + ".dll";
        string assemblyPath;

        if (assemblyName.EndsWith(".resources"))
        {
            // Specific resources are located in app subdirectories
            string resourceDirectory = Path.Combine(applicationDirectory, assemblyCulture);

            assemblyPath = Path.Combine(resourceDirectory, assemblyFileName);
        }

        }
