C# HttpListener: IE11 does not apply CSS

Question

我编写了一个简单的HttpListener应用程序，它为脱机html应用程序提供服务。在firefox中一切正常，但是IE不能应用css文件中的样式。它请求它们，我将它们发送回来，但它不应用它们…

// Construct a response.
List<byte> bytes = new List<byte>();
using (FileStream fs = new FileStream(path, FileMode.Open))
using (BinaryReader br = new BinaryReader(fs))
    while (br.BaseStream.Position != br.BaseStream.Length)
        bytes.Add(br.ReadByte());
buffer = bytes.ToArray();
// Get a response stream and write the response to it.
response.ContentLength64 = buffer.Length;
response.RedirectLocation = path;
switch (ext)
{
    case "css":
        mime = "text/css";
        break;
    case "js":
        mime = "text/javascript";
        break;
    case "png":
        mime = "image/png";
        break;
    case "jpg":
        mime = "text/jpeg";
        break;
    case "gif":
        mime = "image/gif";
        break;
}
response.AddHeader("content", mime);
using (Stream output = response.OutputStream)
    output.Write(buffer, 0, buffer.Length);
break;

Answer 1

就像Eser说的，

response.ContentType = mime;
