Question

I need a regular expression to basically get the first part of a string, before the first slash ().

For example in the following:

C:\MyFolder\MyFile.zip

The part I need is “C:“

Another example:

somebucketname\MyFolder\MyFile.zip

I would need “somebucketname“

I also need a regular expression to retrieve the “right hand” part of it, so everything after the first slash (excluding the slash.)

For example

somebucketname\MyFolder\MyFile.zip

would return

MyFolder\MyFile.zip.

Answer 1

You don’t need a regular expression (it would incur too much overhead for a simple problem like this), try this instead:

yourString = yourString.Substring(0, yourString.IndexOf('\\'));

And for finding everything after the first slash you can do this:

yourString = yourString.Substring(yourString.IndexOf('\\') + 1);
