C# 实现从程序集中抽取内嵌资源文件

　　从嵌入的资源文件读取文件，并释放到指定目录：

    //从资源文件释放模板文件
            Assembly assembly = System.Reflection.Assembly.GetEntryAssembly();

            string[] resNames = assembly.GetManifestResourceNames();  //列出所有资源名称
            //string fileName = assembly.GetName().Name + ".Resources.Rc1.grf";
            
            foreach (var itemResFileName in resNames)
            {
                if (itemResFileName.EndsWith(EXTEN_NAME_TEMPLATE))
                {
                    var arr_Names = itemResFileName.Split('.');
                    string fileName = string.Concat(arr_Names[arr_Names.Length - 2], EXTEN_NAME_TEMPLATE);
                    string outPutFileFullName = Path.Combine(templateDir, fileName);
                    if (File.Exists(outPutFileFullName))
                    {
                        continue;
                    }

                    FileUtility.ExtractResFile(assembly, itemResFileName, outPutFileFullName);
                }
            }
