我正在尝试从托管C＃应用程序（.NET Framework 2.0）中未处理的异常处理程序中编写一个minidump：
namespace MiniDumpTest {
class Program {
static void Main(string[] args) {
AppDomain.CurrentDomain.UnhandledException += new UnhandledExceptionEventHandler(CurrentDomain_UnhandledException);
Console.WriteLine("started");
try {
Console.WriteLine(MyFunc());
} finally {
Console.WriteLine("finished");
Console.ReadLine();
}
}
static void CurrentDomain_UnhandledException(object sender, UnhandledExceptionEventArgs e) {
if (MiniDump.MakeDump(@"D:\Work\Visual Studio.NET\MiniDumpTest\MiniDumpTest\bin\Release\MyDump.dmp", MiniDumpType.WithFullMemory)) {
Console.WriteLine("MiniDump written");
} else {
Console.WriteLine("Failed to write MiniDump");
}
}
static int MyFunc() {
int i = 0;
++i;
if (i == 1) {
throw new ApplicationException("bla");
}
return i;
}
}
public static class MiniDump {
public static bool MakeDump(String dmpPath, MiniDumpType dmpType) {
MinidumpExceptionInfo mMei;
mMei.ThreadId = GetCurrentThreadId();
mMei.ExceptionPointers = Marshal.GetExceptionPointers();
mMei.ClientPointers = false;
using (FileStream stream = new FileStream(dmpPath, FileMode.Create)) {
Process process = Process.GetCurrentProcess();
IntPtr mem = Marshal.AllocHGlobal(Marshal.SizeOf(mMei));
Marshal.StructureToPtr(mMei, mem, false);
Boolean success = MiniDumpWriteDump(
process.Handle,
process.Id,
stream.SafeFileHandle.DangerousGetHandle(),
dmpType,
mMei.ClientPointers ? mem : IntPtr.Zero,
IntPtr.Zero,
IntPtr.Zero);
Marshal.FreeHGlobal(mem);
return success;
}
}
[DllImport("DbgHelp.dll", SetLastError = true, CallingConvention = CallingConvention.Winapi)]
private static extern Boolean MiniDumpWriteDump(
IntPtr hProcess,
Int32 processId,
IntPtr fileHandle,
MiniDumpType dumpType,
IntPtr excepInfo,
IntPtr userInfo,
IntPtr extInfo);
[DllImport("kernel32.dll")]
private static extern int GetCurrentThreadId();
[StructLayout(LayoutKind.Sequential)]
struct MinidumpExceptionInfo {
public Int32 ThreadId;
public IntPtr ExceptionPointers;
public bool ClientPointers;
}
}
public enum MiniDumpType {
Normal = 0x00000000,
WithDataSegs = 0x00000001,
WithFullMemory = 0x00000002,
WithHandleData = 0x00000004,

WithCodeSegs = 0x00002000,
WithoutAuxiliaryState = 0x00004000,
WithFullAuxiliaryState = 0x00008000
}
}
在分析WinDbg中的minidump时，即使PDB匹配并且所有路径（符号，源，图像）都设置正确，调用堆栈中也缺少源行信息。
我在WinDbg中得到以下输出：
