c# - LINQ to SQL 中的内部连接不起作用

Question

我的代码有什么问题？对于 Funcionario 表和 Projeto 表用红色下划线...

DataContext db = new projfuncionarioDataContext();

var query = from p in db.Funcionario
            join c in db.Projeto on p.Cdfunc equals c.Cdfunc
            select new
            {
              ID = p.Cdfunc,
              Produto = p.Nome,
            };

GridView1.DataSource = query;
GridView1.DataBind();

Answer 1

DataContext db = new projfuncionarioDataContext(); 

应该是:

projfuncionarioDataContext db = new projfuncionarioDataContext();
