c# cast problem

Question

Really boggled.

Code
public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
{
string[] ss = (string)value.Split("|");

This throws a compile error. Now since I am casting the field "value" I cannot see why the Split method is not useable. I can simply case value to another field defined as string and then use that field in the Split method. Why can I not do the whole thing in one statement?

Answer 1

Hi @Lloyd Sheen ,
(string) is converted last.
So string[] ss = (string)value.Split("|");, What actually happens is the following steps.

string[] a = value.Split("|");  
string[] ss = (string)a;  

It is recommended to use your step-by-step code, or try string[] ss = value.ToString().Split("|");.

Best Regards.
