Why no Directory.Copy in C# [closed]

Question

I am making a program in C# with a lot of IO operations. Some of that operations are copying directories.

I was really stunned when I figured out that you don't have something like Directory.copy(SourceDir, DestinationDir) in C#.

I googled a little bit around and at msdn they give a code sample to copy directories. (http://msdn.microsoft.com/en-us/library/bb762914.aspx). But when you search a little bit further, there is a Directory.Copy method in the Microsoft.VisualBasic.FileIO namespace. (http://msdn.microsoft.com/en-us/library/ms127957.aspx)

I could refere to this namespace and use this method, but there must be a reason why Microsoft does not support this in C# and why they aren't mentioning it on msdn.

Hope somebody can tell me the reason.

I can write extensionmethod to solve this problem & I can solve it pretty easy, but my question is Why? Why is there no such method in C#, I just want to know :-)

Answer 1

Because it's easy enough to do a foreach on a DirectoryInfo.GetFiles(), while also giving you an opportunity to filter the list of files being copied, or do some other operation besides copying.

If it really bothers you, write an extension method for the DirectoryInfo class, or a FileInfo[] collection.
