passing array in tag property of control (C#.net winforms)

I am dynamically building controls on a screen and need to attach some values for later reference to each control.  I attached an array of 2 values to each control through the Tag property.  So now I'm where I need to get those values out but I cannot figure out the syntax to access them.  Sorry if this is a lame question...I'm new at C#.net.  This is how I attached them:

                string[] strCtrlArray = new string[2];
                strCtrlArray[0] = strReportParameterName;
                strCtrlArray[1] = strParmCtrlProperty;

                    Type ctype = Type.GetType(strClsName);
                    objCtrl = Activator.CreateInstance(ctype);

                    strProp = "Tag";
                    pinf = ctype.GetProperty(strProp);
                    pinf.SetValue(objCtrl, strCtrlArray, null);
                   
                    this.Controls.Add(objCtrl as Control);

I know the values are there in an array because I can see them in debug.    But I can't figure out the syntax to get them out.

Thank you so much for your help!
