Errors in c#

Question

Hi friends  When i open my project  any form contained my class is noticed with errors  some of that are like this : Could not find type 'ERP2010_11.Class.Class_GPPanel'. Please make sure that the assembly that contains this type is referenced. If this type is a part of your development project make sure that the project has been successfully built. The variable 'GP_Noidung' is either undeclared or was never assigned. I do not know how to solve this  I can not open any form at this time . I need help from you all  Thanks .

I downloaded new components from Dotnetbar tools this morning and the errors can come from it . But i had used Dotnetbar component ( not full ) without error .

Look at the references of your project. Click on References node in Solution Explorer. You will see some errors in some assemblies referenced in your project. You need to either install them or readd them by deleting and adding the back (if they are locally stored in your project's bin folder). You may also be using a different version of a product.
