Declaring a global variable in ASP.NET codebehind

Question

I want to declare a Dictionary<string, object> variable but don't know where/how to. The values in the dictionary will be objects from the Page (ListBoxes, DropDownLists, etc) so I can't exactly create a helper class somewhere else. Is there any way I can make this variable accessible from each method in the codebehind?

Answer 1

Declare the variable inside the class, but outside of any method. for Example:

namespace WebApplication1
{
    public partial class _Default : System.Web.UI.Page
    {
        private Dictionary<string, object> myDictionary;

        protected void Page_Load(object sender, EventArgs e)
        {
            myDictionary = new Dictionary<string, object>();
            myDictionary.Add("test", "Some Test String as Object");
        }

        protected void TextBox1_TextChanged(object sender, EventArgs e)
        {
            myDictionary.Add("TextBox1Value", TextBox1.Text);
        }

        protected void Button1_Click(object sender, EventArgs e)
        {
            TextBox1.Text = myDictionary["test"].ToString();
        }
    }
}
