.NET（Mono）是否支持跨平台文件操作和跨平台音频元数据处理（通过库）？

[英]Does .NET (Mono) support cross-platform file operations and cross-platform audio metadata handling (through libraries)?

For my next project, the two leading frontrunners are .NET and Java. 对于我的下一个项目，.NET和Java是两个领先的领跑者。 The project is to take a directory (something like My Music in Windows) that contains directories and music files (MP3s initially, but eventually expanded to other music formats). 该项目将获取一个包含目录和音乐文件（最初为MP3，但最终扩展为其他音乐格式）的目录（类似于Windows中的“我的音乐”）。 For each file, it would allow you to play the file and view/edit its metadata, filename, and location. 对于每个文件，它将允许您播放文件并查看/编辑其元数据，文件名和位置。

I know that Java has libraries for both getting/editing metadata and cross-platform support for file operations. 我知道Java具有用于获取/编辑元数据的库以及对文件操作的跨平台支持。 I also know that .NET has libraries for dealing with the metadata, but I'm not sure about the file operations I need. 我也知道.NET具有用于处理元数据的库，但是我不确定所需的文件操作。 However, I really want to get back into .NET, especially since I want to keep it on my resume, but I haven't used it since .NET 2.0 (and it's, what, 3.5 now?) and if I don't keep up with it, there's no point in putting it on my resume since I couldn't answer any questions about new versions of the technology. 但是，我真的很想回到.NET，特别是因为我想将其保留在我的简历中，但是自.NET 2.0（现在是3.5，现在）以来，我就再也没有使用它了，如果我不这样做的话。跟上它，因为我无法回答有关该技术的新版本的任何问题，所以将它放在简历上毫无意义。

Initially, Windows is my only concern, but I would like to release this as a cross-platform application. 最初，Windows是我唯一关心的问题，但我想将其作为跨平台应用程序发布。

Note: I do know that I'm reinventing the wheel, but this is a problem that I've encountered and I think it would be kind of fun to solve. 注意：我确实知道我正在重新发明轮子，但这是我遇到的一个问题，我认为解决这个问题会很有趣。 It deals with a number of problems, from UI concerns to file structure management to external libraries and more. 它涉及许多问题，从UI问题到文件结构管理再到外部库等等。

The official page from mono on the first part of this topic is IOMap . mono的官方页面是IOMap 。

Mono now has a portability layer into Mono that will address those problems without requiring changes to your code. Mono现在在Mono中具有一个可移植性层，可以在不更改代码的情况下解决这些问题。 This will remove a large component of the porting cycle as a whole class of obnoxious problems are gone. 这将消除移植周期的很大一部分，因为一整类令人讨厌的问题都消失了。

The new portability framework is enabled by setting the environment variable MONO_IOMAP (which we will likely rename to something shorter) to one of the following values: 通过将环境变量MONO_IOMAP （我们可能会将其重命名为更短的名称）设置为以下值之一来启用新的可移植性框架：

case: makes all file system access case insensitive. case：使所有文件系统访问不区分大小写。

drive: strips drive name from pathnames. drive：从路径名中删除驱动器名称。

all: enables both case and drive. all：同时启用大小写和驱动器。

In addition, if any of those options are enabled, the directory separator mapping is also turned on. 此外，如果启用了这些选项中的任何一个，则目录分隔符映射也会打开。
