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

I have an .NET EXE file . I want to find the file created date and modified date in C# application. Can do it through reflection or with IO stream?

You could use below code:

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