类型系统的未处理异常。发生在System.Windows.Forms.d ObjectDisposedException”

I am working with visual studio 2012 C# windows form application. I am simply setting up my flow of forms by button_click events i.e form1 has a button Click Next which will close current form and open a new form Form2. Form2 has a "Click Next" Button which takes to Form3 and so on. In my forms, I am using form1.show() and form1.close() at required places. Please, look into this and replies are welcome.I am facing an Exception as I am working with visual studio 2012 C# windows
