问题描述

我已经在我的MVC应用程序中使用以下代码显示图像这是我的控制器的代码

Hi, i'm already display images using the following code in my MVC application this is the code of my controller

var recordEventUploadFile = new RecordEventUploadFile();
           var ext="";
           var filePath = "";
           int i=0;
           var fileDetails = _reportReviewActionMethods.GetUploadFilePath(fileId);
           recordEventUploadFile.FilePath = fileDetails.FilePath;
           recordEventUploadFile.FileExtension = fileDetails.FileExtension;
           filePath = recordEventUploadFile.FilePath;
           var fileExtension = recordEventUploadFile.FileExtension;
           string[] ExtensionWODot = fileExtension.Split('.');
           if (ExtensionWODot[1].ToLower()== "pdf")
               ext = "application/" + ExtensionWODot[1].ToLower();
           else
           {
               ViewBag.ImagePath = fileDetails;
               return File(filePath, "image/" + ExtensionWODot[1].ToLower());
           }
           return File(filePath, ext);

推荐答案

由于CP网站问题，评论按钮现在不可用，因此我将此作为解决方案发布，当评论按钮返回时，将其重新定位为注释。



您显示的代码是方法的摘录;不知道该方法返回的内容很难给你反馈。



如果你想要显示的代码来处理多个文件，那么你必须显然，给它一些方法来传入一个文件列表，或者在一个变量中可用，或者你必须传入一个目录路径，然后从该目录中选择符合你条件的文件（和/或它的子目录）。



为什么不从实现开始，但是方法会知道哪些文件...或者，如何查找文件。 ..你想要显示？

The "Comment" button is not available right now because of a CP site problem, so I'll post this as a "solution," and re-locate it as comment when the "Comment" button returns.

The code you show is an excerpt from a method; without knowing what is done with what the method returns it is hard to give you feedback.

If you want the code you show to handle multiple files, then you have to, obviously, give it some way to have a list of files passed in, or available in a variable, or you have to have a directory path passed in, and then select the files that match your criteria from within that directory (and/or its sub-directories).

Why don't you start by implementing however it is the method will know what files ... or, how to find the files ... you want displayed ?
