c#批量上傳圖片到服務(wù)器示例分享

這篇文章主要介紹了c#批量上傳圖片到服務(wù)器示例，服務(wù)器端需要設(shè)置圖片存儲的虛擬目錄，需要的朋友可以參考下

客戶端代碼：

/// <summary>
/// 批量上傳圖片
/// </summary>
/// <param name="srcurl">服務(wù)器路徑</param>
/// <param name="imagesPath">圖片文件夾路徑</param>
/// <param name="files">圖片名稱</param>
public void UpLoadFile(string srcurl, string imagesPath, List<string> files)
{
    int count = 1;
    foreach (string imageName in files)
    {
string name = imageName;
string url = null;
//+ 加號特殊處理
if (name.Contains("+"))
{
    url = srcurl + "name=" + name.Replace("+", "%2B");
}
else
{
    url = srcurl + "name=" + name;
}

FileStream fs = new FileStream(imagesPath + name, FileMode.Open);
byte[] data = new byte[fs.Length];
fs.Read(data, 0, data.Length);
fs.Close();

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
request.ContentType = "image/jpeg";
request.Method = "POST";
Encoding encoding = Encoding.UTF8;
request.ContentLength = data.Length;
Stream requestStream = request.GetRequestStream();
requestStream.Write(data, 0, data.Length);
requestStream.Close();

HttpWebResponse response = (HttpWebResponse)request.GetResponse();
StreamReader streamReader = new StreamReader(response.GetResponseStream(), encoding);
string retString = streamReader.ReadToEnd();
streamReader.Close();

Console.WriteLine((count++) + "/" + files.Count);

}
}

服務(wù)器端代碼：

復(fù)制代碼代碼如下:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Net;
using System.Text;
using System.IO;

public partial class upload : System.Web.UI.Page
{

protected void Page_Load(object sender, EventArgs e)
{
string fPath = Server.MapPath("服務(wù)器端圖片存儲的虛擬目錄名稱");//得到虛擬目錄的真實(shí)路徑//檢查存儲目錄
if (!Directory.Exists(fPath))
{
Directory.CreateDirectory(fPath);
}
string name = Request.QueryString["name"];//得到文件名
HttpUtility.UrlEncode(name, Encoding.GetEncoding("UTF-8"));

if (name != null)
{
    if (!File.Exists(fPath + name))
    {
System.IO.Stream stream = Request.InputStream;
byte[] buffer = new byte[stream.Length];
FileStream fs = null;
try
{
    fs = new FileStream(fPath + name, FileMode.Create);
    while ((stream.Read(buffer, 0, buffer.Length)) > 0)
    {
fs.Write(buffer, 0, buffer.Length);
    }
}
catch (IOException ioe)
{
    Response.Write(ioe);
}
finally
{
    if (fs != null)
    {
fs.Close();
}
    stream.Close();
}
Response.Write(name + "<br>");
Response.Write(File.Exists(fPath + name) + "<br>");
}
}
Response.Write("上傳完畢" + Directory.Exists(fPath) + Path.GetFullPath(fPath));
}
}
