using System.Diagnostics;
using System.Linq;
using System.Text;
using Microsoft.Diagnostics.Runtime;namespace CSharpUtils.wrc.utils.debugging
{public static class StackTraceAnalysis{public static string GetAllStackTraces(){var result new StringBuilder();using (var target DataTarget.CreateSnapshotAndAttach(Process.GetCurrentProcess().Id)){var runtime target.ClrVersions.First().CreateRuntime();// We cant get the thread name from the ClrThead objects, so well look for// Thread instances on the heap and get the names from those. var threadNameLookup new Dictionaryint, string();foreach (var obj in runtime.Heap.EnumerateObjects()){if (!(obj.Type is null) obj.Type.Name System.Threading.Thread){var threadId obj.ReadFieldint(m_ManagedThreadId);var threadName obj.ReadStringField(m_Name);threadNameLookup[threadId] threadName;}}foreach (var thread in runtime.Threads){threadNameLookup.TryGetValue(thread.ManagedThreadId, out string threadName);result.AppendLine($ManagedThreadId: {thread.ManagedThreadId}, Name: {threadName}, OSThreadId: {thread.OSThreadId}, Thread: IsAlive: {thread.IsAlive}, IsBackground: {thread.IsBackground});foreach (var clrStackFrame in thread.EnumerateStackTrace())result.AppendLine(${clrStackFrame.Method});}}return result.ToString();}}
}点评区 其实是这样的如何想自动化获取当前的进程中所有线程的调用栈用 ClrMD 即可如果是为了对程序进行分析诊断可以借助 windbg再使用 sos 中的 ~*e !clrstack 命令即可比如下面这样0:000 ~*e !clrstack
