大家好，欢迎来到IT知识分享网。
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";
}
