asp. net Method for remote uploading pictures based on Web Service

This paper gives an example of how asp. net can upload pictures remotely based on Web and Service. Share it for your reference, as follows:

Page calling code: If you add Web reference,

HttpFileCollection files = HttpContext.Current.Request.Files;
string filePath = files[0].FileName;
string fileName = filePath.Substring(filePath.LastIndexOf("//") + 1);
byte[] datas = new byte[files[0].ContentLength];
System.IO.Stream fs;
localhost.WebService web = new localhost.WebService();
fs = (System.IO.Stream)files[0].InputStream;
// Read the input stream into 2 In the dimension array 
fs.Read(datas, 0, files[0].ContentLength);
fs.Close();
Response.Write(web.UploadFile(datas,fileName));

Code in Web Service

[WebMethod(Description=" Upload the server picture information and return whether it is successful or not ")]
public string UploadFile(byte[] fs,string fileName)
{
  // Create a memory flow   Write an array to a memory stream 
  MemoryStream memory = new MemoryStream(fs);
  // Write something from memory to the file stream 
  FileStream stream = new FileStream(HttpContext.Current.Server.MapPath(".") + "//images" + fileName,FileMode.Create);
  // Writes something from the memory stream to FileStream In stream 
  memory.WriteTo(stream);
  stream.Close();
  memory = null;
  stream = null;
  return " File uploaded successfully !";
}

I hope this paper is helpful to everyone's asp. net programming.
