Answer 1

最基本的分析是 !analyze -v，它已经对您的情况有所帮助。确保您的 symbols are correct第一的。所以以下3条命令足以找出异常:

0:000> .symfix
0:000> .reload
0:000> !analyze -v
[...]
CLR_EXCEPTION
    Tid    [0x0]
    Frame  [0x00]

    String [System.ArgumentNullException]
    Failure Bucketing
    Data Bucketing

BUGCHECK_STR:  CLR_EXCEPTION_System.ArgumentNullException    
DEFAULT_BUCKET_ID:  CLR_EXCEPTION_System.ArgumentNullException
[...]

对于 .NET，还有一个名为 sos 的扩展名这可以帮助:

0:000> .loadby sos clr
0:000> !pe
Exception object: 00000000045ff3b8
Exception type:   System.ArgumentNullException
Message:          Value cannot be null.
InnerException:   <none>
StackTrace (generated):
    SP               IP               Function
    00000000003EDC20 000007FEDB83F49D System_Core_ni!System.Linq.Enumerable.SequenceEqual[[System.Byte, mscorlib]](System.Collections.Generic.IEnumerable`1<Byte>, System.Collections.Generic.IEnumerable`1<Byte>, System.Collections.Generic.IEqualityComparer`1<Byte>)+0x22d

StackTraceString: <none>
HResult: 80004003

您可能还需要调用堆栈:

0:000> !clrstack
The version of SOS does not match the version of CLR you are debugging.  Please
