如何从文件扩展名中获得MIME类型?
当前回答
您可以在注册表中找到这些信息。例如，.pdf文件的MIME类型可以在键HKEY_CLASSES_ROOT\.pdf中找到，在值"Content type "中:
string mimeType = Registry.GetValue(@"HKEY_CLASSES_ROOT\.pdf", "Content Type", null) as string;
其他回答
我已经编写了一个程序来获取和转换Apache mime。类型文件到c#字典<字符串，字符串>的关键文件扩展名。这里的。
实际的输出是这个文件(但是您可能希望获取它并再次运行它，以防Apache文件在我上次运行之后已经更新)。
public static Dictionary<string, string> MimeTypes = new Dictionary<string, string>
{
{ "123", "application/vnd.lotus-1-2-3" },
{ "3dml", "text/vnd.in3d.3dml" },
{ "3g2", "video/3gpp2" },
{ "3gp", "video/3gpp" },
{ "7z", "application/x-7z-compressed" },
{ "aab", "application/x-authorware-bin" },
{ "aac", "audio/x-aac" },
{ "aam", "application/x-authorware-map" },
{ "aas", "application/x-authorware-seg" },
{ "abw", "application/x-abiword" },

IANA媒体类型
我希望微软能把他们的行业标准统一起来!对于其他人，有兴趣的人:
离散的类型

多部分类型
信息:https://www.iana.org/assignments/media-types/media-types.xhtml消息 多部分:https://www.iana.org/assignments/media-types/media-types.xhtml #多部分
我想推荐一个阅读:MIME类型(IANA媒体类型)的Mozilla页面感兴趣的人!它的信息量很大!
在代码方面，上面的每个链接都有一个.csv文件下载:https://www.iana.org/assignments/media-types/application.csv
正如这里已经指出的，可以使用Dictionary或ConcurrentDictionary下载并使用Key - Value对填充Dictionary。
当然，为了将通用完整性、动态性和可移植性的优势与最小的依赖性结合起来
你将结合Samuel Neff的静态字典与特定平台的查询，例如由Bryan Denny。
例如，在Linux下，命令行工具“xdg-mime”可以完成后面的部分。
更新
对于许多贡献者添加的最新映射，请参阅这个GitHub存储库:
https://github.com/samuelneff/MimeTypeMap
和NuGet包
https://www.nuget.org/packages/MimeTypeMapOfficial/
我发现我的应用程序使用的许多mime类型不在默认的Windows注册表中，其他类型在注册表中，但不在IIS包含的列表中。我从这些地点整理了一个列表，并添加了一些我们使用的其他地点。
编辑:在这里查看最新版本的贡献，包括一个有效和确定的双向映射。
