C implements the HTTP download method

This article illustrated how C# implements HTTP download files. Share to everybody for everybody reference.

The main implementation codes are as follows:

/// <summary>

/// Http The download file 

/// </summary>

public static string HttpDownloadFile(string url, string path)

{

    //  Set the parameters 

    HttpWebRequest request = WebRequest.Create(url) as HttpWebRequest;
    // Send the request and get the corresponding response data 

    HttpWebResponse response = request.GetResponse() as HttpWebResponse;

    // until request.GetResponse() The application then starts sending to the target page Post request 

    Stream responseStream = response.GetResponseStream();
    // Create a local file to write to stream 

    Stream stream = new FileStream(path, FileMode.Create);
    byte[] bArr = new byte[1024];

    int size = responseStream.Read(bArr, 0, (int)bArr.Length);

    while (size > 0)

    {

        stream.Write(bArr, 0, size);

        size = responseStream.Read(bArr, 0, (int)bArr.Length);

    }

    stream.Close();

    responseStream.Close();

    return path;

}
