目录无法找到路径的一部分 [英] Directory could not find a part of the path

问题描述

    lstfile.Items.Clear();

            DirectoryInfo dir = new DirectoryInfo(lstfolder.SelectedValue );
            foreach (FileInfo fi in dir.GetFiles())
            {
                lstfile.Items.Add(fi.ToString());
            }
runtime error Could not find a part of the path

我尝试过：



这是一个运行时错误，所以还没有做任何事情

What I have tried:

it's a runtime error so not yet do anything

推荐答案

这意味着你是尝试从不存在的文件夹中访问文件。

检查lstfolder列表中的值并确认文件夹是否存在。



代码：

It means you are trying to access the files from a folder which is not present.
Check the values from the lstfolder list and verify physically that the folders are present or not.

in code:

DirectoryInfo dir = new DirectoryInfo(lstfolder.SelectedValue);
          if (dir.Exists)
          {
              foreach (FileInfo fi in dir.GetFiles())
              {
                  lstfile.Items.Add(fi.ToString());
              }
          }

参考： DirectoryInfo.Exists [ ^ ]

lstfolder中的内容是什么？ />


如果它只包含目录名，那么你必须使用，



Server.Mappath（directoyname）





这有助于检索目录的整个路径。



然后跟随KARTHIK说。

What is in "lstfolder"?

If it contains only Directory names, then you have to use,

Server.Mappath(directoyname)


This helps in retrieving entire path of the directory.

Then follow as KARTHIK said.
