当我尝试在 db2 服务器中执行数据集时出现此异常。最奇怪的是单元测试代码不会抛出异常，但是当我尝试从网页中使用相同的参数调用它时，它会抛出异常。
这是我的单元测试代码：
[Test]
public void Get_the_car_details_via_the_chassisnumber_WVWZZZ1KZCW240208()
{
//Arrange
string chassisNumber = "WVWZZZ1KZCW240208";
string brand = "skoda";
//Act
Vehicle car = VehicleDA.GetVehicle(chassisNumber, "", brand).GetResult();
//Assert
Assert.IsNotNull(car);
car.Type.ShouldBe("VOLKSWAGEN GOLF");
}
这是我从页面中调用它的方式，如您所见，我对相同的参数进行了硬编码，但它仍然不起作用
public Vehicle GetVehicleInformation(string chassis, string commissionnumber, string brand)
{
Vehicle car = VehicleDA.GetVehicle("WVWZZZ1KZCW240208", commissionnumber, "skoda").GetResult();
这是dal中的DB代码
public class VehicleDA

public static ResultForType<Vehicle> GetVehicle(string chassisNumber, string commissionNumber, string brand)
