I have a static class:
namespace GVN
{
static class ClData
{
public static string cltNM {get; set;}
}
}
But, when I try to use it,
label_nm.Text = ClData.cltNM;
this error appears: ( http://msdn.microsoft.com/library/vstudio/sxw2ez55 )
Even if I perform this manually:
ClData.cltNM = "12345";
Before:
label_nm.Text = ClData.cltNM;
How can I avoid this error?
Your problem is that label_nm
is null
, rather than the static
string
variable, or the error is not in fact on the line of code that you've indicated. Even if cltNM
is null
it wouldn't throw a null reference exception on that line.
