在C＃.net下载文件从资源库 [英] Download Files From Resource Library in c# .net

问题描述

我发展的地方，从多个屏幕的用户必须下载一个示例文件（Excel文件）一起工作的应用程序。会有什么preferable的方式来做到这一点。

I am developing an application where from several screens user has to download a sample file(excel) to work with. What will be the preferable way to do so.

我在做什么是

配售文件在执行应用程序，并使用Application.StartupPath下载文件的目录。这不听起来像是一个非常好的解决方案。由于在任何时候用户可以编辑文件或删除文件或这样的事情。

Placing the file in the directory where application is executing and download the files using Application.StartupPath. This does not sounds like a very good solution. As at anytime user could edit the files or delete the files or such things.

我想要做的就是

我想从资源添加的所有文件在我的资源和下载文件。我想补充的文件，但我需要关于如何从资源下载的帮助不大。

I want to add all the files in my resources and download files from the resources. I add the files but i need a little help on how to download it from resources.

推荐答案

您可以使用：

 class ResourceHelper
    {
           public static void MakeFileOutOfAStream(string stream, string filePath)
            {
                using(var fs = new FileStream(filePath,FileMode.Create,FileAccess.ReadWrite))
                {
                    CopyStream(GetStream(stream), fs);
                }
            }

            static void CopyStream(Stream input, Stream output)
            {
                byte[] buffer = new byte[32768];
                int read;
                while ((read = input.Read(buffer, 0, buffer.Length)) > 0)
                {
                    output.Write(buffer, 0, read);
                }
            }
 static Stream GetStream(string stream)
        {
             return Assembly.GetExecutingAssembly().GetManifestResourceStream(stream));

        }
    }

和与流过的你资源的完整名称，即命名空间+资源文件名（evantual夹将被认为是命名空间的一部分）的情况下敏感。请记住，标志项目文件作为嵌入资源

and with stream pass the complete name of you resource, that is the namespace + the resource file name ( evantual folder are to be considered as namespace part ) case sensitive. Remember to flag the file in your project as embedded resource.
