How to trim .key off the end of string

[laurasaur]

Hiya guys, have read in a file name but its in a weird format, like
this
filename.date.key

i need to trim off .key any ideas? TrimEnd is not filling me with joy.

Cheers

Laura,

Did you ever had a look at the path class, seems exactly made for your
question.

if (filename.EndsWith(".key"))
{
filename = filename.Substring (0, filename.Length-4);
}

The get extension methods of the path class dont work in my situation,
as the filename has many periods in it, ie
filename.date.time.key

so getextension doesnt work in this situation as far as I can tell

 

[laurasaur]

if (filename.EndsWith(".key"))
{
filename = filename.Substring (0, filename.Length-4);

}

I did something similar in the end,

//string name = the file name string

int position = name.LastIndexOf('.');
string Sendbak = name.Remove(position);

As I already know that the file will always have a .key extension.
Thanks for all your help everyone

If you already know it will already have a .key extension, you can just
use:

string Sendbak = name.Remove(name.Length-4);

Somehow I'd managed to miss the addition of the "Remove" method in 2.0
