Android 使用 MultipartEntity ，C# 怎么接受这个参数

[gavinluo]

//向服务器端上传图片
public String UploadImage(String url, Map<String, String> param,File file)throws Exception{
String result = "";
HttpPost post = new HttpPost(url);

MultipartEntity entity = new MultipartEntity();
if (param != null && !param.isEmpty()) {
for (Map.Entry<String, String> entry : param.entrySet()) {
if (entry.getValue() != null
&& entry.getValue().trim().length() > 0) {
entity.addPart(entry.getKey(),new StringBody(entry.getValue()));

}
}
}
// 添加文件参数
if (file != null && file.exists()) {
entity.addPart("file", new FileBody(file)); //该怎样接收file文件呢
}
post.setEntity(entity);

HttpClient httpClient = new DefaultHttpClient();
//执行上传
HttpResponse response = httpClient.execute(post);
//StringBuffer sb = new StringBuffer();

if (response.getStatusLine().getStatusCode() == HttpStatus.SC_OK) {
result = retrieveInputStream(response.getEntity());
Log.e("ykp","图片上传：" + result);
}

post.abort();
return result;
}

服务器端我用的WCF的RestFul，我用Stream 参数接受到数据后，本以为可以直接写文件，但保存出来的文件根本打不开，随后弄了半天，发现这个流里的总长度和 Android端的总长度不一致，转换成字符串后发现还有下列东西，请问这样的数据C#怎么处理，

Content-Disposition: form-data; name="attachment"; filename="2014_07_09_17_51_41.jpg"
Content-Type: application/octet-stream
Content-Transfer-Encoding: binary

此处应该是对应图片的乱码

如果不是很复杂，就不需要MultipartParser了，直接跳过头部简单。

internal static byte[] GetBytesFromStream(Stream stream, System.Text.Encoding encoding)
{
	// Read the stream into a byte array
	byte[] data = ToByteArray(stream);
	List<byte> dataList = new List<byte>();

	// Copy to a string for header parsing
	string content = encoding.GetString(data);

	string matchValue = "Content-Transfer-Encoding: binary\r\n\r\n";
	int lastIndex = content.LastIndexOf(matchValue);

	int startingIndex = lastIndex + matchValue.Length;

	byte[] bytes = encoding.GetBytes(content.Substring(0, startingIndex - 1));
	int bytesLength = bytes.Length;

	for (int i = bytesLength + 1; i < data.Length; i++)
	{
		dataList.Add(data[i]);
	}

	return dataList.ToArray();
}

你好 有DEMO吗 还是不懂
