cURL用C＃调用flag

我想在C＃中进行以下curl调用：

curl "http://localhost:8983/solr/update/extract?literal.id=doc1&commit=true" -F "myfile=@tutorial.html" 

我发现我应该使用WebRequest类，但我仍然不确定如何处理这部分：

 -F "myfile=@tutorial.html"

来自http://msdn.microsoft.com/en-us/library/debx8sh9.aspx的代码片段显示了如何使用WebRequest类发送POST数据：

 // Create a request using a URL that can receive a post. WebRequest request = WebRequest.Create("http://localhost:8983/solr/update/extract?literal.id=doc1&commit=true"); // Set the Method property of the request to POST. request.Method = "POST"; // Create POST data and convert it to a byte array. string postData = "myfile=@tutorial.html"; byte[] byteArray = Encoding.UTF8.GetBytes(postData); // Set the ContentType property of the WebRequest. request.ContentType = "application/x-www-form-urlencoded"; // Set the ContentLength property of the WebRequest. request.ContentLength = byteArray.Length;

作为WebRequest的替代方法，您可以考虑使用WebClient类。 它提供了比WebRequest更清晰，更简单的语法。 像这样的东西：

 using (WebClient client = new WebClient()) { client.Headers[HttpRequestHeader.ContentType] = "application/x-www-form-urlencoded"; byte[] postResult = client.UploadFile("http://localhost:8983/solr/update/extract?literal.id=doc1&commit=true", "POST", "tutorial.html"); }
