C#使用HTML文件中的file文件上傳，用C#代碼接收上傳文件

單獨作圖片上傳很簡單，若是要客戶端要上傳頭像保存到服務器就要稍微麻煩一點點了。

很少說了，直接上源碼：

private void Upload()        

{

            string jsonInfo = string.Empty;

　　

　　　　///這句是關鍵，它是獲取HTTP中文件流 的對象集合。

            HttpFileCollection hfc = System.Web.HttpContext.Current.Request.Files;

            string mobile = string.IsNullOrEmpty(Request.Form["mobile"]) ? Request.QueryString["mobile"] : Request.Form["mobile"];

            string fName = "";

            // string.IsNullOrEmpty(Request.Form["filename"]) ? Request.QueryString["filename"] : Request.Form["filename"];

            string status = string.Empty;

            string error = string.Empty;

　　　　///在這裏咱們只取其中一個上傳對象操做

             fName = hfc[0].FileName;

            try

            {

                string[] list;

                if (!string.IsNullOrEmpty(fName))

                {

                    list = fName.Split('.');

                    if (list.Length > 1)

                    {

                        string ftype = list[1].ToLower();

                        if (ftype == "jpg" || ftype == "png" || ftype == "jpeg")

                        {

                            fName = mobile + "." + list[1];

                            string filePath = "../CSS/headmiages/";

                            hfc[0].SaveAs(System.IO.Path.Combine(MapPath(filePath), fName));

                            RockUserInfo userInfo = new RockUserInfo();

                            userInfo.LogOnPhoneNum = mobile;

                            //根據手機號查詢出用戶基本信息

                            userInfo = SearchByPhone(userInfo);

                            userInfo.filename = fName;

                            //插入頭像信息保存

                            Save(userInfo);

                            status = "0";

                            error = "";

                        }

                        else

                        {

                            status = "1";

                            error = "請上傳 .jpg/.png/.jpeg/類型的圖片";

                        }

                    }

                }

                else

                {

                    status = "1";

                    error = "請上傳 .jpg/.png/.jpeg/類型的圖片";

                }

                //fileload.in

            }

            catch (Exception ex)

            {

                status = "2";

                error = ex.ToString();

            }

            jsonInfo = "{\"" + "status" + "\":\"" + status + "\"," + "msg" + "\":\"" + error + "}";

            Response.Write(jsonInfo);

        }

這樣就 OK了，在服務器端保存上傳文件，操做數據庫就基本達到目標了。很簡單吧！

這段代碼通過測試是沒有問題的，若是有不合理之處還望你們指出來共同進步。
