single line string maninuplation substring, trim, indexof ?

[Jason]

I have a string that looks like this?

ihelloworld_zzz _yyy

In a single vb.net line, I want to remove the frist character and
anything after and including the first "_"

resulting in :

helloworld

I've been trying things like this:

Dim cleanname = c.ID.Remove(1). Substring(0, c.ID.IndexOf("_ "c))

Dim cleanname = c.ID.subsrting( 1,c.id.Length). Substring(0,
c.ID.IndexOf("_ "c))

the error I get is that the index is out of bounds becasue it's a
substring of a substring and the index I guess has changed.

thanks.

Jason,

Without testing,

myNewString as string = "ihelloworld_zz z_yyy".Substrin g(1,10)

I hope this goes,

Cor

sorry, the helloworld string is an example and might be longer or
shorter.

Try:

Dim str As String = "ihelloworld_zz z_yyy"

str = str.Substring(1 , str.IndexOf("_" ) - 1)

Thanks,

Why is the number of lines important to you? I would think readability
and correctness mattered more.
