.NET Ftp查看圖片

其實FTP查看圖片很簡單,首先我們要根據用戶名，密碼，還有服務器地址登錄上ftp服務器。
然后把前端對應顯示圖片名稱傳到后台即可。我前端顯示圖片是采用的easyui彈框，其實只需一個image標簽即可。
如下代碼：

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

 
//js代碼
function OclickAttachmentFile() {
        $('#dlg').dialog({  
            title: '簽證預覽',  
            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>
        //獲取文件
        //</summary>
        //<param name="fillName">圖片名稱</param>
        //<returns>圖片流</returns>
        public FileResult GetFileUpload(string fillName)
        {
            string usercConfig = ScmConfig.CusReceiptFtpUser; //服務器用戶名
            string pwdcConfig = ScmConfig.CusReceiptFtpPwd; //服務器密碼
            string ftpSrccConfig = ScmConfig.CustomerReceiptFtp; //服務器地址
            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");

        }
