Jump to Post"ChrW"?? This one??
If ligne is a string how could it read from a CSV. It will be usefull if give the sample coding in which ligne,ChrW are related.. Me too don't know VB. I need to make a try?
Jump to PostIts taking a string called ligne, splitting it at char 59 (that's a semicolon), and assigning valeur as index zero of the split.
C# equivalent of that
string valeur = ligne.Split(';')[0];

That is a piece of this code, just look about it,may be it will be better for you.

C# equivalent of that
string valeur = ligne.Split(';')[0];

The ChrW() function "returns a character associated with the specified character code."
Here's a list of character codes. DEC 59 is a ';'. :)
EDIT: I am sorry, I've never even heard of ZedGraph.
