原来的写法:
Dim db = From city In DataContext1.AddressCity
Where city.ProvinceID = dgvAddress(2, e.RowIndex).Value.ToString 、
Select city.CityID, city.CityName.Trim
可以去掉CityName中的空格,但是db中的列名改变了,在绑定Combobox中出现了错误。
修改后的写法:
Dim db = From city In DataContext1.AddressCity
Where city.ProvinceID = dgvAddress(2, e.RowIndex).Value.ToString
Select New With {.CityID = city.CityID, .CityName = city.CityName.Trim}
可以正确绑定Combobox了。
