[2.0] How to extract a portion of a variable in C#

Its quite easy in VB (Instr function).

I have username stored in a string variable. the content of the variable is "//xx.com/nathb". I would like to extract only "nathb" portion . How can I do that in C#?

thanks

There are many string manipulation functions in .NET: .Substring, .IndexOf(), etc. which you can use to get what you need. In your case, you appear to want the text from the string after the last forward-slash.

Code:

---

string original = "//xx.com/nathb";
string extracted = original.substring(original.LastIndexOf("/"));

---

May need a bit of tweaking.

That string is a path so you can use the IO.Path class:

Code:

---

string path = "//xx.com/nathb";
string userName = System.IO.Path.GetFileName(path);

---

That's what I'd do in VB too.

or you could use split function.

Or regular expressions :D

There are four ways to skin string x = "a dead cat";

Serialize the dead cat to a memory stream, move the stream position to one layer below the Skin object and then deserialize again. Optionally Deserialize the skin at a later point if needed.
