            {
                category_id     = 1, 
                barcode         = "DDH-003",
                asset_number    = "45645645", 
                equipment_name  = "DBD Dew", 
                equipment_description = "Thin Can", 
                manufacturer_id = 3, 
                model           = "Blah", 
                serialnumber    = "11111", 
                status          = "Good", 
                service_group   = "SGE", 
                required_pm     = "Yes", 
                service_provider="111", 
                frequency       = 1, 
                department_id   = 1, 
                location_id     = 1, 
                availability    = "Avail", 
                register_id     = 1, 
                supplier_id     = 1, 
                conditionstatus_id = 1, 
                status_id       = 1, 
                utilization_id = 3
            };
            int count = con.Insert<equipment>(eqp); <-- error here
            if (count > 0) 
            {
                MessageBox.Show("Successfully Added", "Successfully Added -:", MessageBoxButtons.OK, MessageBoxIcon.Information); 
            }
            con.Close();

        }

Dapper 假定您的数据库模型中有一个名为 Id 的列，除非您另有指定。另一方面，在这种情况下，您使用的是来自 Dapper.Contrib 的扩展。为此，您必须在[key]主键上方添加一个指令。
