很久沒寫文章了,最近公司的案子很趕,沒什麼時間研究新東西

今天就寫一篇簡單的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

<%@ WebService Language="C#" CodeBehind="~/App_Code/Fileupload.cs" Class="Fileupload" %>

Fileupload.cs

using System; using System.Web; using System.Collections; using System.Web.Services; using System.Web.Services.Protocols; using System.IO; /// <summary> /// Fileupload 的摘要描述 /// </summary> [WebService(Namespace = "http://tempuri.org/")] [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] public class Fileupload : System.Web.Services.WebService { public Fileupload() { } [WebMethod] public string UploadFile(byte[] fs, string fileName) { try { MemoryStream memoryStream = new MemoryStream(fs); FileStream fileStream = new FileStream(Server.MapPath(@"~\upload\" + fileName), FileMode.Create); memoryStream.WriteTo(fileStream); memoryStream.Close(); fileStream.Close(); fileStream = null; memoryStream = null; return "上傳成功"; } catch (Exception ex) { return ex.Message; } } }

在WebForm或WinForm專案都要加入Web參考,如下圖所示

WebForm

ServiceFileupload.aspx

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="ServiceFileupload.aspx.cs" Inherits="ServiceFileupload" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" > <head runat="server"> <title>ServieFileupload</title> </head> <body> <form id="form1" runat="server"> <div> <asp:FileUpload ID="FileUpload1" runat="server" /> <asp:Button ID="btnUpload" runat="server" OnClick="btnUpload_Click" Text="Upload" /></div> </form> </body> </html>

ServiceFileupload.aspx.cs

using System; using System.Data; using System.Configuration; using System.Collections; using System.Web; using System.Web.Security; using System.Web.UI; using System.Web.UI.WebControls; using System.Web.UI.WebControls.WebParts; using System.Web.UI.HtmlControls; using Service_Fileupload; public partial class ServiceFileupload : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { } protected void btnUpload_Click(object sender, EventArgs e) { if(this.FileUpload1.HasFile) { Response.Write(new Fileupload().UploadFile(this.FileUpload1.FileBytes, this.FileUpload1.FileName)); } } }

WinForm

ServiceFileupload.cs

using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Text; using System.Windows.Forms; using System.IO; using WindowsApplication1.Service_Fileupload1; namespace WindowsApplication1 { public partial class ServiceFileupload : Form { public ServiceFileupload() { InitializeComponent(); } private void btnOpen_Click(object sender, EventArgs e) { OpenFileDialog f = new OpenFileDialog(); f.ShowDialog(this); this.txbPath.Text = f.FileName; } private void btnUpload_Click(object sender, EventArgs e) { this.label1.Text = new Fileupload().UploadFile(File.ReadAllBytes(this.txbPath.Text), Path.GetFileName(this.txbPath.Text)); } } }
