in class library project use??WebServiceHandlerFactory?to create Web service, http://www.codeproject.com/useritems/wsinaclasslibrary.asp
write a class WebServiceBase to implements webserviceHandlerFactory, then implement your web service inherit from this class, and copy this compoment into your web app bin directory, then add <add path="WSTest.asmx" verb="*" type="WSLibrary.WSTest" validate="false"/> into your web.config's httphandler section.

[WebMethod(EnableSession=true)]XXX 此聲明可以在WS中引用session對(duì)象, 某種程度上可以提高性能; 但需要客戶(hù)端在調(diào)用時(shí)支持,默認(rèn)情況下browser中調(diào)用WS時(shí)要有SESSION的,而在普通的EXE或程序中調(diào)用WS時(shí),需要顯示聲明要使用cookie,否則服務(wù)器端的session無(wú)效..net 中聲明如下:
WebService1 srv = new WebService1();
srv.CookieContainer = new CookieContainer();
只有經(jīng)過(guò)這樣聲明,調(diào)用的WS才會(huì)傳遞SESSIONID,建立在一個(gè)應(yīng)用中只有一個(gè)地方可獲取WS,即采用singleton模式,這樣所有地方調(diào)用WS時(shí)都有sessionID支持.

利用WS上傳文件,可以在CLIENT中將文件中的內(nèi)容讀取到byte[]中,然后調(diào)用WS接口,然后WS再將byte寫(xiě)入到文件中
轉(zhuǎn)換FileStream fileStream = File.OpenRead(path + fileName);為MemoryStream,再轉(zhuǎn)換為byte[].
public 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();
??????? }
如果是將byte[]寫(xiě)入到文件,則代碼如下:
{
??????????????? MemoryStream memoryStream = new MemoryStream(fs);
??????????????? FileStream fileStream = new FileStream(path + fileName, FileMode.Create);
??????????????? memoryStream.WriteTo(fileStream);
??????????????? memoryStream.Close();
??????????????? fileStream.Close();
??????????????? fileStream = null;
??????????????? memoryStream = null;
