I define a variable in a class, and initial it in Page_Load function.
Then I define another function in this class with [AjaxPro.AjaxMethod],
the problem is I can't use the variable, I wonder why.
The codes look like:
/////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
public class GisShow : System.Web.UI.Page
{
private System.Random r = new Random();
private int[] m_nErrArray;
private void Page_Load(object sender, System.EventArgs e)
{
AjaxPro.Utility.RegisterTypeForAjax(typeof(GisShow));
m_nErrArray = (int[])Application.Get("ErrArray");
}
[AjaxPro.AjaxMethod]
public void InitLightInfo()
{
for ( int i = 0; i < m_nErrArray.Length; i++) // <- Error here
{
m_nErrArray[i] = r.Next(-1, 16);
}
}
/////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
The error is: "Object reference not set to an instance of an object"
Anybody know the reasons of this error? And how can I use the variables
of the class?Thanks.
