Of course, the process of downloading movies in these three proces

This article introduces some basic knowledge of Internet communication programming with Visual C # through an example. We know. NET class includes the request/response layer, the Application protocol layer, the Transport layer and so on. In this program, we use the WebRequest class at the request/response level and the WebClient class to achieve a high degree of abstraction in Internet communication services. The function of this program is to complete the downl

FileStream class. Where the WebClient class is in the System.Net namespace, the primary function of this class is to provide a public method for sending data to and receiving data from the resource identified by the URI. We use the DownloadFile () method to download the network file locally. The file data is then written to the local file using the instance object of the FileStream class as a data stream. This completes the download of the network fi
consistent, this need to implement the client to screen cloud server and interface differences, and provide a unified operating interface, so in the implementation of this client at the same time, We have implemented a framework that is common to servers and interfaces, such as taking a file download to say. Our implementation is probably as follows:

receiving data from the resource identified by the URI. We use the DownloadFile () method to download the network files locally. The file data is then written to the local file using the instance object of the FileStream class as a data stream. This completes the download of the network files.
Implementation steps
First, open Visual Studio.NET and create a new project for a visual C#windows application that you might name as "Mygetcar." Next, lay out

The DownloadFile method downloads data from a URI and saves it as a local file
The OpenRead method opens and performs a read operation in the form of a stream
The Openwrite method opens a stream for writing data to the URI
The Uploaddata method uploads data to the URI
The UploadFile method uploads a local file to the development URI
