File details from a string in C#

Question

Hello, I have a string in C#

String file="\\mserver-80\docs\somedoc.doc"

Now How do I get fileInfo from the above sting. What I mean is, I want to declare something like

FileInfo fInfo = new FileInfo(file);
fileExtn = fInfo.Extension;

Answer 1

That code will work fine, using the FileInfo class.

Simply add

using System.IO;

However, note that the \ must be escaped as \\.
Instead, you should use an @"" string, like this:

String file = @"\\mserver-80\docs\somedoc.doc"

Answer 2

In C# the string should be

String file="\\\\mserver-80\\docs\\somedoc.doc";

You can also escacpe the string using the @ character, which is a better alternative:

String file=@"\\mserver-80\docs\somedoc.doc";

other than that the code should work.

Answer 3

You can also try

Path.GetExtension(file)
