C# determines whether the folder exists and performs deletion and creation operations
useIn namespaceDirectoryClass to delete local folders and all their contents, or create new folders when they do not exist.
1. Determine whether the folder exists, if it does not exist, create a new folder.
The parameter 'folderParh' is the full path of the incoming folder.
// Create a new folder private void isExists(string folderPath)
{
try
{
// Determine whether the folder exists if (!(folderPath))
{
// If the folder does not exist, create a folder (folderPath);
("The folder does not exist and has been created successfully.");
}
else
{
("The folder already exists.");
}
}
catch (Exception ex)
{
//Catch and handle exceptions ("An error occurred while operating the folder: " + );
}
}2. Determine whether the folder exists, and delete the folder if it exists
//Delete the folder private void delFile(string folderPath )
{
try
{
// Check if the folder exists if ((folderPath))
{
// Delete the folder and all its contents (folderPath, true);
("The folder and its contents have been deleted successfully.");
}
else
{
("The specified folder does not exist.");
}
}
catch (Exception ex)
{
//Catch and handle exceptions ("An error occurred while deleting a folder: " + );
