Controller层
?public JsonResult DataSpecialAttachmentImage(HttpPostedFileBase fileData) ???????{ ???????????//获取页面上的内容名字 ???????????string infoname = Convert.ToString(Request["Data_Special_Name"]); ???????????//再设置内容名字格式和当前创建时间 ???????????string filename = fileData.FileName.Insert(fileData.FileName.LastIndexOf(‘.‘), "_" + infoname + "_" + DateTime.Now.ToString("yyyyMMddHHmmss")); ???????????//设置保存的路径 ???????????string localPath = Server.MapPath(@"\Content\UploadImages\") + filename; ???????????FileInfo file = new FileInfo(localPath); ???????????if (!file.Exists) ???????????{ ???????????????Stream stream = new FileStream(localPath, FileMode.Create); ???????????????byte[] bArr = new byte[1024]; ???????????????int size = fileData.InputStream.Read(bArr, 0, (int)bArr.Length); ???????????????while (size > 0) ???????????????{ ???????????????????stream.Write(bArr, 0, size); ???????????????????size = fileData.InputStream.Read(bArr, 0, (int)bArr.Length); ???????????????} ???????????????stream.Close(); ???????????????var result = new { State = "Success", FileName = filename }; ???????????????return Json(result, JsonRequestBehavior.AllowGet); ???????????} ???????????else ???????????{ ???????????????var result = new { State = "Exites", Message = "文件已存在！" }; ???????????????return Json(result, JsonRequestBehavior.AllowGet); ???????????} ???????}因用的是datatable框架 ，就写View层只写部分视图代码
"render": function (data, type, row) { ???????return "<img src=‘/Content/UploadImages/" + row.Data_Image + "‘ width=‘60px‘/>" ???}, ???"targets": 5《工作日记》 2019-01-18 在程序中图片显示（上传图片）
