将 Web 服务 POST 从 Java 转换为 .NET

Question

下面是从连接到网站并通过 POST 方法上传文件的 Java 客户端的片段。我必须在 Visual Studio 环境中重现此客户端，但我在 .NET 环境中没有看到 Java 中使用的 setEntity() 函数的任何等效函数。

我发现的一切都指向使用这个...

public void uploadFile(File uploadFile, String partner, String key,
            String baseUrl,boolean isPartner) throws IOException {
    DefaultHttpClient httpclient = new DefaultHttpClient();
    httpclient.getParams().setParameter(
        CoreProtocolPNames.PROTOCOL_VERSION, HttpVersion.HTTP_1_1
    );
    String url = baseUrl + "?" + (isPartner ? "partnerId" : "ori") + "="
            + partner.toUpperCase() + "&authKey=" 
            + key+ "&key=" 
            + key;
    HttpPost httppost = new HttpPost(url);
    MultipartEntity multipartEntity = new MultipartEntity();
    ContentBody contentBody = new FileBody(uploadFile, "text/xml"); 
    multipartEntity.addPart("dataFile", contentBody); 
    httppost.setEntity(multipartEntity);

    HttpResponse response;
    response = httpclient.execute(httppost);

    HttpEntity resEntity = response.getEntity();

    if (resEntity != null) {
        resEntity.consumeContent();
    }

    httpclient.getConnectionManager().shutdown();
}

我在 Visual Studio 中找到的所有东西都使用下面这样的 POST 方法。 WebRequest 对象没有明显的方法来添加我需要的参数。

Dim request As WebRequest = WebRequest.Create("http://Test.com/import?partnerId=2&authKey=XdUa")
request.Method = "POST"
Dim postData As String = StrData
Dim byteArray As Byte() = Encoding.UTF8.GetBytes(postData)
request.ContentType = "dataStr"
request.ContentLength = byteArray.Length
Dim dataStream As Stream = request.GetRequestStream()
dataStream.Write(byteArray, 0, byteArray.Length)
dataStream.Close()
Dim response As WebResponse = request.GetResponse()

任何指导将不胜感激。如果我的问题不清楚，请告诉我，我会再试一次。

可以添加如下代码sn-p来添加参数

request.ContentType="application/x-www-form-urlencoded"

Dim postData As String = "name1="+value1+"&name2="+value2

Dim byteArray As Byte() = Encoding.UTF8.GetBytes(postData)

休息将保持不变。
