This article will explain in detail how to implement the C# Web Services upgrade program. The editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.

This paper introduces an upgrade program with C # Web Services. Upgrading the program through C # Web Services is as simple as reading and writing native files. So I just gave the code.

Part of the code of the C# Web Services upgrade program:

Using System; using System.Web; using System.Web.Services; using System.Web.Services.Protocols; using System.IO; [WebService (Namespace = "http://tempuri.org/")] [WebServiceBinding (ConformsTo = WsiProfiles.BasicProfile1_1)] public class Service: System.Web.Services.WebService {public Service () {/ / if you use the designed component, uncomment the following line / / InitializeComponent () } / summary > private const string UpdateServerPath = "d:\\ Debug"; [WebMethod (Description = "return the version number of the program on the server")] public string ServerVer () {return "4.0";} [WebMethod (Description = "return the file to be updated")] public string [] NewFiles () {DirectoryInfo di = new DirectoryInfo (UpdateServerPath); FileInfo [] fi = di.GetFiles () Int intFiles= fi.Length; string [] myNewFiles = new string [intFiles]; int I = 0; foreach (FileInfo fiTemp in fi) {myNewFiles [I] = fiTemp.Name; System.Diagnostics.Debug.WriteLine (fiTemp.Name); iTunes;} return myNewFiles;} [WebMethod (Description = "return the size of the file to be updated")] public int AllFileSize () {int filesize = 0; string [] files = Directory.GetFiles (UpdateServerPath) Foreach (string file in files) {FileInfo myInfo = new FileInfo (file); filesize + = (int) myInfo.Length / 1024;} return filesize;} [WebMethod (Description = "return a byte array of a given file")] public byte [] GetNewFile (string requestFileName) {/ / get a file if (requestFileName! = null | | requestFileName! = ") return getBinaryFile (UpdateServerPath +"\ "+ requestFileName) on the server side; else return null } / returns a byte array of the given file path. / / summary > / / param > / / returns > private byte [] getBinaryFile (string filename) {if (File.Exists (filename)) {try {/ / Open an existing file for reading. FileStream s = File.OpenRead (filename); return ConvertStreamToByteBuffer (s);} catch {return new byte [0];}} else {return new byte [0];}} / converts the given file stream into a binary byte array. / / summary > / / param > / / returns > private byte [] ConvertStreamToByteBuffer (System.IO.Stream theStream) {int b1; System.IO.MemoryStream tempStream = new System.IO.MemoryStream (); while ((b1 = theStream.ReadByte ())! =-1) {tempStream.WriteByte (byte) b1));} return tempStream.ToArray () }} this is the end of the article on "how to implement the C # Web Services upgrade program".
