C# 將外部exe檔存在程式內，調用時再提取出來使用

流程

將外部exe檔變成內部資源檔
利用Properties.Resources.<資源名>並搭配方法可以在運行時將其提取出來

提取內部exe的方法

public static void GenerateExe(byte[] FileBytes, string DestinationPath)
        {
            try
            {
                //1) Fetch Exe file content from Resources
                byte[] memoryFile = FileBytes;

                //2) Create file to be deleted complete execution
                FileStream aFile = new FileStream(DestinationPath, FileMode.Create, FileAccess.Write, FileShare.None, 20000, FileOptions.None);

                //3) Write Exe file content
                aFile.Write(memoryFile, 0, memoryFile.Length);
                aFile.Flush();
                aFile.Close();
                Thread.Sleep(100);
            }
            catch (Exception e)
            {
                Console.WriteLine(e.Message);
                DeleteExeFile();
            }

        }

調用方法

string fullPath = Application.StartupPath + @"\aria2c.exe";
ExeManager.GenerateExe(Properties.Resources.aria2c, fullPath);
