C# implements batch download of pictures to local sample code

1. Overview

Batch downloading of pictures is a requirement that we often encounter in daily development. Recently, we need to batch download pictures to the local area in our work. First, we generate all link addresses through Excel splicing, and then we think of batch downloading by downloading software. But when I think about taking time to find, install and research software, it is better to write it yourself faster.

The following is the console program code developed using C# to read each line of the address string in the text file by looping to perform downloading and saving it to a local folder.

I won't say much below, let's take a look at the detailed introduction

2. C# instance code

//using System;
//using ;
//using ;
//using ;
//--------------------------------------------

static void Main(string[] args)
{
 //StreamReader reads int count = 0;
 using (Stream readerStream = new FileStream(@"d:\", ))
 using (StreamReader reader = new StreamReader(readerStream, Encoding.UTF8))
 using (WebClient client = new WebClient())
 {
  string line;
  while ((line = ()) != null)
  {
   count++;
   (line + " " + count);
   Uri uri = new Uri(line);
   if (uri!=null)
   {
    string filename = ();
    (uri, @"c:\pictures\"+filename);
    ("document:"+filename+"Downloaded successfully!" + "Count:"+ count);
   }
   else
   {
    ("path:" + line + "Not download address! Failed serial number:"+count );
   }
   
  }
 }

 ("Download is complete!");
 ();
}
