一篇簡單的Web Service上傳檔案,並且整合在WebFrom與WinForm使用者介面

首先要準備一支Web Service(上傳檔案用,WebForm或WinForm都會call這支)

接下來準備WebForm與WinForm的UI介面來上傳檔案

Web Service

Fileupload.asmx

view plaincopy to clipboardprint?
  1. <%@ WebService Language="C#" CodeBehind="~/App_Code/Fileupload.cs" Class="Fileupload" %>  

Fileupload.cs

view plaincopy to clipboardprint?
  1. using System;  
  2. using System.Web;  
  3. using System.Collections;  
  4. using System.Web.Services;  
  5. using System.Web.Services.Protocols;  
  6. using System.IO;  
  7.   
  8.   
  9. /// <summary>  
  10. /// Fileupload 的摘要描述  
  11. /// </summary>  
  12. [WebService(Namespace = "http://tempuri.org/")]  
  13. [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]  
  14. public class Fileupload : System.Web.Services.WebService  
  15. {  
  16.     public Fileupload()  
  17.     {  
  18.   
  19.     }  
  20.   
  21.     [WebMethod]  
  22.     public string UploadFile(byte[] fs, string fileName)  
  23.     {  
  24.         try  
  25.         {  
  26.             MemoryStream memoryStream = new MemoryStream(fs);  
  27.             FileStream fileStream = new FileStream(Server.MapPath(@"~\upload\" + fileName), FileMode.Create);  
  28.             memoryStream.WriteTo(fileStream);  
  29.             memoryStream.Close();  
  30.             fileStream.Close();  
  31.             fileStream = null;  
  32.             memoryStream = null;  
  33.             return "上傳成功";  
  34.         }  
  35.   
  36.         catch (Exception ex)  
  37.         {  
  38.             return ex.Message;  
  39.         }  
  40.     }  
  41. }  

在WebForm或WinForm專案都要加入Web參考,如下圖所示

WebForm

ServiceFileupload.aspx

  25.         }  
  26.     }  
  27. }  

WinForm

  14.     {  
  15.         public ServiceFileupload()  
  16.         {  
  17.             InitializeComponent();  
  18.         }  
  19.   
  20.         private void btnOpen_Click(object sender, EventArgs e)  
  21.         {  
  22.             OpenFileDialog f = new OpenFileDialog();  
  23.             f.ShowDialog(this);  
  24.             this.txbPath.Text = f.FileName;  
  25.         }  
  26.   
  27.         private void btnUpload_Click(object sender, EventArgs e)  
  28.         {  
  29.             this.label1.Text = new Fileupload().UploadFile(File.ReadAllBytes(this.txbPath.Text), Path.GetFileName(this.txbPath.Text));  
  30.         }  
  31.     }  
  32. }
