[RESOLVED] static method problem

Hi there,

I am doing an ASPX site with c# as the code behind. I haven't done this in a while but I needed to create a static class to check some variables - I stole this little bit of code of the net but I am having a problem.

This is the class.

Code:

---

public static class QueryStringCheck
{


    public static bool HasValue(object o)
    {
        if (o == null)
        {
            return false;
        }

        if (o == System.DBNull.Value)
        {
            return false;
        }

        if (o is String)
        {
            if (((String)o).Trim() == String.Empty)
            {
                return false;
            }
        }

        return true;
    }

}

---

This is the code I am calling to make use of it...

Code:

---

if(!QueryStringCheck.Equals((object)Request.QueryString["TransactionId"]))
{
          Response.Redirect("/MyAccount/PurchaseHistory.aspx");
}

---

But I get the error message
Error 12 An object reference is required for the nonstatic field, method, or property 'object.Equals(object)'

Now I remember going over this in school but it isn't like I can ever remember needing a static method (well having to create one myself - use ehm all the time)

Can anyone point out what I am missing - I just re-read some material on the subject but it didn't seem to help? I don't see anything wrong.

Thanks

Two things -

One, call the right method
Two, the string doesn't need to be cast as an object...

Duh for me!!!!
