如何查詢IIS的MIME類型映射？

Question

如何以編程方式讀取IIS的MIME類型？當我將數據傳輸到客戶端時，我想使用它們using WCF。

任何提示或API，將不勝感激註冊到系統

Answer 1

MIME類型在註冊表中「HKEY_CLASSES_ROOT \啞劇\數據庫\內容類型」定義。

您是否正在尋找IIS中定義的特定網站的MIME類型？

我正在做的假設，這是IIS7只有你正在使用C＃3.0或更高版本：

using Microsoft.Web.Administration; 
.... 
using(ServerManager serverManager = new ServerManager()) 
{ 
    // If interested in global mimeMap: 
    var config = serverManager.GetApplicationHostConfiguration(); 

    // Use if interested in just a particular site's mimeMap: 
    // var config = serverManager.GetWebConfiguration("Default Web Site"); 

    var staticContent = config.GetSection("system.webServer/staticContent"); 
    var mimeMap = staticContent.GetCollection(); 

    // Print all mime types 
    foreach (var mimeType in mimeMap) 
    { 
    Console.WriteLine(String.Format("{0} = {1}", mimeType["fileExtension"], 
     mimeType["mimeType"])); 
    } 

    // Find a mime type based on file extension 
    var mt = mimeMap.Where(
     a => (string) a.Attributes["fileExtension"].Value == ".pdf" 
    ).FirstOrDefault(); 

    if (mt != null) 
    { 
    Console.WriteLine("Mime type for .pdf is: " + mt["mimeType"]); 
    } 
} 

您需要引用Microsoft.Web.Administration.dll在c:\windows\system32\inetsrv。

您的代碼也需要管理員權限才能做到這一點。

作爲替代讀取註冊表，或在config目錄降低安全性，有內HTML Agility Pack

如果使用ASP.Net 4.5或更高版本，可以使用System.Web.MimeMapping.GetMimeMapping如下預填充的MIME數據庫：

void Page_Init() 
{ 
    string[] extensions = new string[] 
    { 
     ".pdf", 
     ".xls", 
     ".xlsx", 
     ".ppt", 
     ".pptx", 
     ".mp3", 
     ".ogg", 
     ".svg", 
     ".pdf", 
     ".png", 
    }; 

    foreach (string extension in extensions) 
    { 
     string mimeType = MimeMapping.GetMimeMapping(extension); 
     Response.Write(String.Format("{0} => {1}<br />", 
       extension, 
       mimeType 
      )); 
    } 
} 

結果：

.pdf => application/pdf 
.xls => application/vnd.ms-excel 
.xlsx => application/vnd.openxmlformats-officedocument.spreadsheetml.sheet 
.ppt => application/vnd.ms-powerpoint 
.pptx => application/vnd.openxmlformats-officedocument.presentationml.presentation 
.mp3 => audio/mpeg 
.ogg => video/ogg 
.svg => image/svg+xml 
.pdf => application/pdf 
.png => image/png
