我知道有很多关于这个主题的问题，但没有一个为我的问题提供答案。这就是为什么我要创建一个新问题。
我在 google 和 here 上查看了答案，并发现了一些改进了我的 AutoMapper 设置的方法。（即只创建一次映射）
我的问题是我有时会遇到异常，有时却不会。我完全不知道如何解决它。我已经搜索了一整天，但我找不到任何东西。
当我运行 Mapper.AssertConfigurationIsValid(); 它成功了。
我尝试添加以下内容：
Mapper.Configuration.AllowNullDestinationValues = true;
Mapper.AllowNullDestinationValues = true;
我仍然得到错误：s
我的设置如下：
在我的 global.asax 文件中，我调用 AutoMapperSetup.SetupAutoMapper()。
protected void Application_Start(object sender, EventArgs e)
{
...
AutoMapperSetup.SetupAutoMapper();
}
AutoMapperSetup 类描述如下：（我确实知道我的静态构造函数正在执行。如果我放置了一个断点，它就会被命中。所以该代码确实被执行）
public static class AutoMapperSetup
{
static AutoMapperSetup()

当我启动我的 WebServices 时，它会被调用。下一步是从 DB 中获取数据并将其映射到我的 DTO：
FWSGetPlanningResult resultToReturn = Mapper.Map<GetPlanningResult_v3, FWSGetPlanningResult>(result);
执行上面的代码行给了我映射异常错误。下面是异常的详细信息：

我希望有人能给我解决方案..正如您在对象数量上看到的那样..我并不急于开始手动映射所有内容。
