如何从嵌入的资源中提取文件并将其保存到磁盘？ [英] How can i extract a file from an embedded resource and save it to Disk?

问题描述

我试图编译以下使用CSHARP codeProvider的code，该文件被成功编译，但是当我点击生成exe文件，我得到一个错误（Windows正在寻找一个解决这个问题），并没有任何反应。

I'm trying to compile the code below using CSharpCodeProvider, the file is successfully compiled but when i click on the generated exe, i get an error (Windows is searching for a solution to this problem) and nothing happens.

当我编译下面使用CSHARP codeProvider的code，我已经添加了 MySql.Data.dll 作为嵌入资源文件中使用这一行的code：

When i compile the code below using CSharpCodeProvider, i've added the MySql.Data.dll as an embedded resource file using this line of code :

if (provider.Supports(GeneratorSupport.Resources))
    cp.EmbeddedResources.Add("MySql.Data.dll");

该文件被成功嵌入（因为我注意到，文件大小增加）

The file is successfully embedded ( because i noticed the file size increased)

在code以下，我尝试做的是提取嵌入式dll文件并将其保存到System32下 但低于code没有出于某种原因。

In the code below, what i try to do is to extract the embedded dll file and save it to System32 but the code below doesn't work for some reason.

namespace ConsoleApplication1
{
    class Program
    {
        public static void ExtractSaveResource(String filename, String location)
        {
            //  Assembly assembly = Assembly.GetExecutingAssembly();
            Assembly a = .Assembly.GetExecutingAssembly();
            // Stream stream = assembly.GetManifestResourceStream("Installer.Properties.mydll.dll"); // or whatever 
            // string my_namespace = a.GetName().Name.ToString();
            Stream resFilestream = a.GetManifestResourceStream(filename);
            if (resFilestream != null)
            {
                BinaryReader br = new BinaryReader(resFilestream);
                FileStream fs = new FileStream(location, FileMode.Create); // say 
                BinaryWriter bw = new BinaryWriter(fs);
                byte[] ba = new byte[resFilestream.Length];
                resFilestream.Read(ba, 0, ba.Length);
                bw.Write(ba);
                br.Close();
                bw.Close();
                resFilestream.Close();
            }
            // this.Close(); 
        }

        static void Main(string[] args)
        {

            try
            {
                string systemDir = Environment.SystemDirectory;
                ExtractSaveResource("MySql.Data.dll", systemDir);
            }
            catch (Exception ex)
            { 
                Console.WriteLine(ex.Message);
                Console.ReadKey(); 
            } 
        }
    }
}

我怎么能提取嵌作为资源DLL文件并将其保存到System32下？

How can i extract the DLL file that is embedded as a resource and save it to System32?

推荐答案

我一直在使用这种（测试）方法：

I've been using this (tested) method:

OutputDir：要复制的资源位置

OutputDir: Location where you want to copy the resource

ResourceLocation：命名空间（+ dirnames中）

ResourceLocation: Namespace (+ dirnames)

文件：在resourcelocation内的文件列表，要复制

Files: List of files within the resourcelocation, you want to copy.

    private static void ExtractEmbeddedResource(string outputDir, string resourceLocation, List<string> files)
    {
        foreach (string file in files)
        {
            using (System.IO.Stream stream = System.Reflection.Assembly.GetExecutingAssembly().GetManifestResourceStream(resourceLocation + @"." + file))
            {
                using (System.IO.FileStream fileStream = new System.IO.FileStream(System.IO.Path.Combine(outputDir, file), System.IO.FileMode.Create))
                {
                    for (int i = 0; i < stream.Length; i++)
                    {
                        fileStream.WriteByte((byte)stream.ReadByte());
                    }
                    fileStream.Close();
                }
            }
        }
    }
