My logged stack trace seems to be missing a step.
我的日志堆栈跟踪似乎丢失了一个步骤。
private void StartLoadingResources(DataService separateDataService)
{
...
batchResource.Resources.Add(key, new List<string>());
// batchResource.Resources is the Dictionary object involved
...
}
Why has the stack trace gone straight from StartLoadingResources to Insert (missing the Add step)?
为什么堆栈跟踪直接从StartLoadingResources插入(缺少添加步骤)?

The Add method on Dictionary<TKey, TValue> simply calls Insert, given that it's a 1 line method, the compiler has simply inlined that method call as it is so trivial even without optimizations enabled.
