Syntax Challenged

[Jim McGivney]

I find myself Syntax Challenged.
An array resides on a MasterPage.
I want to use the values of the array on an aspx page which is a content
page of the MasterPage.
I can not find the syntax that works.

For a single value (non-array) the following will work.

On the MasterPage:
public String CompanyName
{
get { return (String) ViewState["companyName"]; }
set { ViewState["companyName"] = value; }
}
void Page_Init(Object sender, EventArgs e)
{
this.CompanyName = "JimBo";
}On the ContentPage:<%@ MasterType virtualpath="~/Master1.master" %>void
Page_Load(Object sender, EventArgs e)
{
Label1.Text = Master.CompanyName;
}I need the equivalent code for a array. Code examples would be
appreciated.Thanks,Jim

public String[] MyArray
{
get { return (String[]) ViewState["MyArray"]; }
set { ViewState["MyArray"] = value; }
}

Ray:
This generates an error:
public String[] MyArray
{
get { return (String[])ViewState["MyArray"]; }
set { ViewState["MyArray"] = value; }
}

protected void Button1_Click(object sender, EventArgs e)
{
MyArray[0] = "Zero";
Label1.Text = MyArray[0].ToString();
// Generates error: Object reference not set to an instance of an object.
}

public String[] MyArray
{
get { return (String[]) ViewState["MyArray"]; }
set { ViewState["MyArray"] = value; }
}

I was just showing you how to create the property.

Where are you created the array to set it to the property.

Using:
String[] _a = new String[1] {"Hello"};

You can create the array and then set it to the property:

MyArray = _a;

Then:

MyArray[0] = "Zero" will work.
