You can do that using FileInfo class:

FileInfo fi = new FileInfo("path");
var created = fi.CreationTime;
var lastmodified = fi.LastWriteTime;

File.CreationTime to get Created time

Use :

FileInfo fInfo = new FileInfo('FilePath');
var fFirstTime = fInfo.CreationTime;
var fLastTime = fInfo.LastWriteTime;

You can use this code to see the last modified date of a file.

DateTime dt = File.GetLastWriteTime(path);

And this code to see the creation time.

DateTime fileCreatedDate = File.GetCreationTime(@"C:\Example\MyTest.txt");

You could use below code:

DateTime modification = File.GetLastWriteTime(@"C:\test.txt");

Returns the date and time the specified file or directory was last written to.

string path = @"c:\Temp\MyTest.txt";
DateTime dt = File.GetLastWriteTime(path);

For create time File.GetCreationTime Method

DateTime fileCreatedDate = File.GetCreationTime(@"C:\Example\MyTest.txt");
Console.WriteLine("file created: " + fileCreatedDate);
