asp.net-mvc ASP MVC - 默认内容类型是否有任何常量？

ASP MVC - Are there any constants for the default content types?

提问by Luke Puplett

Is there a set of constants in the framework for all the standard content types?

框架中是否有适用于所有标准内容类型的一组常量？

Taking it as a resounding no, I wrote my own. That's what Sundays were made for.

把它当作一个响亮的不，我写了我自己的。这就是星期日的目的。

System.Net.Mime.MediaTypeNames

回答by Jon

You could use:

你可以使用：

• System.Net.Mime.MediaTypeNames.Application
• System.Net.Mime.MediaTypeNames.Image
• System.Net.Mime.MediaTypeNames.Text

• System.Net.Mime.MediaTypeNames.Application
• System.Net.Mime.MediaTypeNames.Image
• System.Net.Mime.MediaTypeNames.Text

For example, System.Net.Mime.MediaTypeNames.Image.Gifis equal to "image/gif".

例如，System.Net.Mime.MediaTypeNames.Image.Gif等于"image/gif"。

回答by Ilya Chernomordik

In the new ASP.NET Core MimeMappingcan be used with the filename:

在新的 ASP.NET CoreMimeMapping中可以使用文件名：

MimeMapping.GetMimeMapping("1.jpg")

Should return image/jpeg.

应该返回image/jpeg。

All the mappings can be found hereand it is also possible to add your own (see e.g. thisanswer).

所有映射都可以在这里找到，也可以添加自己的映射（参见例如这个答案）。

https://www.nuget.org/packages/MimeTypesMap/is a great NuGet package for this. Use it like this:

https://www.nuget.org/packages/MimeTypesMap/是一个很好的 NuGet 包。像这样使用它：

MimeTypesMap.GetMimeType("filename.jpeg"); // => image/jpeg

or the other way:

或其他方式：

MimeTypesMap.GetExtension("image/jpeg"); // => jpeg
