如何从文件扩展名中获得MIME类型?
当前回答
我已经编译了一个有名的mime类型和内容类型值的来源列表，这些值仅以文件扩展名为键(目前)。
nuget包在这里https://www.nuget.org/packages/FTTLib.dll/
来源在这里https://github.com/brondavies/filetypetranslator/
这个库被设计成:
无外部依赖 没有文件系统访问权限 内存占用小 简单的静态方法(没有扩展方法和可实例化类) 不区分大小写 可移植-工作在应用程序针对任何CLR(。NET 2.0 +)
其他回答
.NET Core获取MimeType的方法:
添加依赖关系
Microsoft.AspNetCore.StaticFiles
private string GetMimeType(string fileName)
{
var provider = new FileExtensionContentTypeProvider();
if (!provider.TryGetContentType(fileName, out var contentType))
{
contentType = "application/octet-stream";
}
return contentType;
}
我更新了一些剧本。以防有人需要
function getMime(){ let ext = fileUpload.value.split('.')[1]; let myOutput = getMimeType(ext); mimeType.value=myOutput; } function getMimeType(ext) { if (!ext.startsWith(".")) { ext = "." + ext; } let myList = [ {"key": ".323", "value": "text/h323"}, {"key": ".3g2", "value": "video/3gpp2"}, {"key": ".3gp", "value": "video/3gpp"}, {"key": ".3gp2", "value": "video/3gpp2"}, {"key": ".3gpp", "value":

你可以使用这个helper函数:
private string GetMimeType (string fileName)
{
string mimeType = "application/unknown";
string ext = System.IO.Path.GetExtension(fileName).ToLower();
Microsoft.Win32.RegistryKey regKey = Microsoft.Win32.Registry.ClassesRoot.OpenSubKey(ext);
if (regKey != null && regKey.GetValue("Content Type") != null)
mimeType = regKey.GetValue("Content Type").ToString();
return mimeType;
}
FileExtension处理文件扩展名，而不是Mime。用户可以更改文件扩展名，因此请检查Mime。代码示例通过文件扩展名关联Mime，这是错误的，不能工作。
需要获取内容类型文件，并检查表Mime contetType该文件根据文件扩展名。现在，如何获得文件的内容类型?
使用FileUpload是这样的: 现在，如果我已经有文件，捕捉你的ContentType?

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。
