常见MimeType大全

使用C#获取MimeType列表

[HttpGet("ExportFile")]
public IActionResult ExportFile()
{
    string path = @"F:\DownLoad\新建文件夹\新建文本文档.txt";
    string fileName = "新建文本文档.txt";
    Stream fs = File.OpenRead(path);

    //获取文件扩展名 
    string fileExt = Path.GetExtension(path);
    //获取文件的ContentType       
    var contentType = new Microsoft.AspNetCore.StaticFiles.FileExtensionContentTypeProvider().Mappings[fileExt];  //.net core 版本 
    //var contentType2 = System.Web.MimeMapping.GetMimeMapping(fileExt); //.net framework 版本
    //var contentType3 = MimeTypes.MimeTypeMap.GetMimeType(fileExt);  //需Neget MediaTypeMap 或者  MediaTypeMap.Core 程序包

    return File(fs, contentType, fileName);
}

MimeType转换与获取

使用Dictionary转换mimeType列表

JsonSerializer.Deserialize<Dictionary<string, string>>(json);

根据文件名获取MimeType

 public static string GetMimeMapping(string fileName)
        {
            if (string.IsNullOrWhiteSpace(fileName))
            {
                throw new ArgumentNullException();
            }
            string key = Path.GetExtension(fileName);
            if (!string.IsNullOrWhiteSpace(key) && dic.ContainsKey(key))
            {
                return dic[key];
            }
            return "application/octet-stream";
        }
