What have you tried? SELECT your filename from the database and then use File.Delete to delete file.

Solution 1

I could have located the file and used File.Delete Method[^] to delete the file from directory.
Try this:

C#

System.IO.File.Delete("MyFilePath");

From your explanation I understood that you want to delete File from uploaded file storage folder.
In Delete click event get the file name and root path of images and delete it using below statement

System.IO.File.Delete("Your file root path with your file name");

If you have multiple files use looping statements.

My explanaiton completly based on unique file names in image storage folder.

Yes, OP need to loop through the directory. See this:
foreach(string fileName in Directory.GetFiles("SomeDirectory"))
{
//your codes here to handle the files.
}

OR

string [] fileEntries = Directory.GetFiles(sourceDir);
foreach(string fileName in fileEntries)
{
// do something with fileName
Console.WriteLine(fileName);
}

Unique file names?
What to do with this? A folder cannot have two files with the same name. And also I can't find much difference in your solution. As OP is telling, filename will come from database, that has to be deleted. So, first check for the file whether it exits or not. If exists then delete.

Try the code given below:

C#

string completePath = Server.MapPath("YourFilePath");

if (System.IO.File.Exists(completePath))
{

System.IO.File.Delete(completePath);

}
