How to read and write shared folders in C#

This article has shared the specific code of C# read and write shared folder for your reference. The specific content is as follows

This test is divided into the following steps:

1. Set up a shared folder on the server. Here, my server IP address is 10.80.88.180, the name of the shared folder is test, and there are two files in the test: and, access permissions, the user name is admin, and the password is admin.

2. Create a new webapplication project, add a listbox to the front page, and the ID is ListBox1.

3. Add the background code as follows: The function contained in it is to read files, here taking reading good files as an example; writing files, here taking writing bad files as an example; and also listing the file names under the test folder into listbox.
