. NET Enterprise Application WebService upload download file

After the establishment of the good one webservice there will be a self-bringing

[webmethod]//writes this in all the methods that will be written, which is easy to        debug  Public string HelloWorld ()        {            return"HelloWorld";        }

Now you can try the entry record.

[WebMethod] PublicUserInfo Login (stringUserName,stringpwd) {            if(UserName = ="Admin"&& pwd = ="123")            {                return NewUserInfo () {username="Admin", pwd="", age= -, remark="I'm very handsome ." }; }            Else            {                return NULL; }        }

Called in the controller in the MVC project

//First step: Add a service reference//Instantiate Service Reference: service object to SoapClientMywebservicesoapclient client =Newmywebservicesoapclient ();  PublicActionResult Index () {stringresult =client.            HelloWorld ();            Response.Write (Result); returnView (); }

[WebMethod]
Public UserInfo Login (string userName, string pwd)
{
if (UserName = = "Admin" && pwd = = "123")
{
return new UserInfo () {username= "admin", pwd= "", age=50,remark= "I'm Handsome"};
}
Else
{
return null;
}
}

Then you can write a simple file upload download

 Public classMyWebService:System.Web.Services.WebService {[WebMethod] Public stringHelloWorld () {return "Hello World"; }        /// <summary>        ///Uploading Files/// </summary>        /// <param name= "bytes" ></param>        /// <param name= "FileName" ></param>        /// <returns></returns>[WebMethod] Public BOOLFileUpload (byte[] Bytes,stringfileName) {            Try            {                //instantiates a Memory object MemoryStream, loads a byte array into a Memory objectMemoryStream memory =NewMemoryStream (bytes); //File Save path                stringFilePath = Server.MapPath ("~/files/"+fileName); //instantiating a File objectFileStream FStream =NewFileStream (FilePath, FileMode.OpenOrCreate); //writing a Memory object to a file objectmemory.

Called in a controller in an MVC project

 PublicActionResult FileUpload () {returnView (); } [HttpPost] Publicactionresult FileUpload (httppostedfilebase file1) {Stream FileStream=File1.
