我想帮忙@mark在问他在哪里的问题上请求 API 从 .NET 故障转储文件中转储许多对象.
所以我使用以下代码编写了mdbgeng
,但不幸的是它失败了NotImplementedException
当尝试枚举内存中的对象时。
using System;
using System.Runtime.InteropServices;
using Microsoft.Samples.Debugging.CorDebug;
using Microsoft.Samples.Debugging.CorDebug.Utility;
using Microsoft.Samples.Debugging.MdbgEngine;
using Microsoft.Samples.Debugging.Native;
namespace DumpHeapFromDotNet
{
class Program
{
static void Main(string[] args)
{
var libraryProvider = new LibraryProvider();
var dumpReader = new DumpReader(args[0]);
var dataTarget = new DumpDataTarget(dumpReader);
foreach (var module in dumpReader.EnumerateModules())
{
var clrDebugging = new CLRDebugging();
Version actualVersion;
ClrDebuggingProcessFlags flags;
CorProcess proc;
var hr = (HResult) clrDebugging.TryOpenVirtualProcess(module.BaseAddress, dataTarget, libraryProvider,
new Version(4, 6, int.MaxValue, int.MaxValue), out actualVersion, out flags, out proc);
if (hr < 0)
{
switch (hr)
{
case HResult.CORDBG_E_NOT_CLR:
Console.WriteLine(module.FullName + " is not a .NET module");
break;
case HResult.CORDBG_E_LIBRARY_PROVIDER_ERROR:
Console.WriteLine(module.FullName + " could not provide library");
break;
case HResult.CORDBG_E_UNSUPPORTED_DEBUGGING_MODEL:
case HResult.CORDBG_E_UNSUPPORTED_FORWARD_COMPAT:
break;
default:
Marshal.ThrowExceptionForHR((int)hr);
break;
}
}
else
{
var objects = proc.Objects; // NotImplementedException
foreach (CorObjectValue o in objects)
{
// TODO: Write details of object to file here
}
}
}
Console.ReadLine();
}
}
}
我使用的转储是具有完整内存的 .NET 4.6.1076.0 转储(您可以传递文件名作为参数):
0:000> lm vm clr

ProductVersion: 4.6.1076.0
FileVersion: 4.6.1076.0 built by: NETFXREL3STAGE

0002 MiniDumpWithFullMemory
0004 MiniDumpWithHandleData

1000 MiniDumpWithThreadInfo
我怀疑这与失踪有关mscordacwks
或类似的,因为我刚刚在同一台计算机上使用与此示例相同的 .NET 框架创建了转储。
是真的还没有实现,还是我做错了什么?
