Answer 2

我做了這個方法前段時間：

public static string GetMimeType(string fileName) 
{ 
    string mimeType = "application/unknown"; 
    string ext = Path.GetExtension(fileName).ToLower(); 
    Microsoft.Win32.RegistryKey regKey = Microsoft.Win32.Registry.ClassesRoot.OpenSubKey(ext); // henter info fra windows registry 
    if (regKey != null && regKey.GetValue("Content Type") != null) 
    { 
     mimeType = regKey.GetValue("Content Type").ToString(); 
    } 
    else if (ext == ".png") // a couple of extra info, due to missing information on the server 
    { 
     mimeType = "image/png"; 
    } 
    else if (ext == ".flv") 
    { 
     mimeType = "video/x-flv"; 
    } 
    return mimeType; 
} 

你可以用它來設置MIME類型，像這樣：

Response.ContentType = GetMimeType(@CompletePhysicalPath);
