问题
I have an exception being thrown from a C# method, that takes a generic list as a paremeter.
private static void DoWork(List<ClassName> a)
{
}
When it throws an exception, the stack trace shows an `1 instead of the class name for the list. Why is this? This is what the stack trace has.
...
at DoWork(List`1 a).

回答1:
The reason why is that the stack trace is generated by the CLR and not C#. Hence it uses CLR type names vs. C# type names.
The type names given to generic types in metadata (in both C# and VB.Net) have the form TypeName`Number where
- TypeName: Name of the type in the abscence of generic parameters
- Number: Count of generic parameters on the type
This is also why it's legal to have several generic classes which the same name but differing numbers of generic parameters. At a CLR level they have different type names.
