.NET Ftp查看图片

其实FTP查看图片很简单,首先我们要根据用户名，密码，还有服务器地址登录上ftp服务器。
然后把前端对应显示图片名称传到后台即可。我前端显示图片是采用的easyui弹框，其实只需一个image标签即可。
如下代码：

<div id="dlg"> ???<img src="" id="simg" /></div>

 
//js代码
function OclickAttachmentFile() { ???????$(‘#dlg‘).dialog({ ?????????????title: ‘签证预览‘, ?????????????width: 800, ?????????????height:650, ?????????????resizable:true, ?????????????closed: false, ?????????????cache: false, ?????????????modal: true ?????????}); ?????????var img = new Image(); ???????$(img).bind("load", function () { ???????????$("#simg").attr("src", this.src); ???????}); ???????img.src = "/Common/file/GetFileUpload?fillName=" + ???????????‘@Model.ErpPoMasterExtModel.DeliveryVoucherOriginName‘; ???}

　 　　　//<summary> ???????//获取文件 ???????//</summary> ???????//<param name="fillName">图片名称</param> ???????//<returns>图片流</returns> ???????public FileResult GetFileUpload(string fillName) ???????{ ???????????string usercConfig = ScmConfig.CusReceiptFtpUser; //服务器用户名 ???????????string pwdcConfig = ScmConfig.CusReceiptFtpPwd; //服务器密码 ???????????string ftpSrccConfig = ScmConfig.CustomerReceiptFtp; //服务器地址 ???????????FtpFileBase ftpFileBase = new FtpFileBase(usercConfig, pwdcConfig); ???????????FtpWebRequest request = (FtpWebRequest)WebRequest.Create(ftpSrccConfig + fillName); ???????????request.Method = WebRequestMethods.Ftp.DownloadFile; ???????????request.Credentials = new NetworkCredential(usercConfig, pwdcConfig); ???????????FtpWebResponse response = (FtpWebResponse)request.GetResponse(); ???????????Stream responseStream = response.GetResponseStream(); ???????????return File(responseStream, "image/jpeg"); ???????}
