      ClassLevel6 nestedClass = new ClassLevel6();
      nestedClass.Level6Method();
   }
   catch (Exception e)

      StackTrace st = new StackTrace();

      // Display the most recent function call.
      StackFrame sf = st.GetFrame(0);
      Console.WriteLine();
      Console.WriteLine("  Exception in method: ");
      Console.WriteLine("      {0}", sf.GetMethod());

      if (st.FrameCount >1)
      {
         // Display the highest-level function call
         // in the trace.

         Console.WriteLine("  Original function call at top of call stack):");
         Console.WriteLine("      {0}", sf.GetMethod());
      }

      Console.WriteLine();
      Console.WriteLine("   ... throwing exception to next level ...");
      Console.WriteLine("-------------------------------------------------\n");
      throw e;
   }
}

Public Sub Level5Method()
   Try
      Dim nestedClass As New ClassLevel6()
      nestedClass.Level6Method()
   Catch e As Exception
      Console.WriteLine(" Level5Method exception handler")

備註

該 是 StackTrace 用呼叫者目前的執行緒建立的，且不包含檔案名稱、行號或欄位資訊。

當你想要完整追蹤，僅包含關於呼叫堆疊的摘要方法資訊時，可以使用這個無參數建構子。

public:
 StackTrace(bool fNeedFileInfo);

public StackTrace(bool fNeedFileInfo);

new System.Diagnostics.StackTrace : bool -> System.Diagnostics.StackTrace

Public Sub New (fNeedFileInfo As Boolean)

範例

以下程式碼範例展示了各種 StackTrace 建構子方法。

   }
   catch (Exception e)

      // Display the full call stack at this level.
      StackTrace st1 = new StackTrace(true);
      Console.WriteLine(" Stack trace for this level: {0}",
         st1.ToString());

      // Build a stack trace from one frame, skipping the current
      // frame and using the next frame.

      // Build a stack trace skipping the current frame, and
      // including all the other frames.
      StackTrace st3 = new StackTrace(1, true);
      Console.WriteLine(" Stack trace built from the next level up: {0}",
         st3.ToString());

      Console.WriteLine();
      Console.WriteLine("   ... throwing exception to next level ...");
      Console.WriteLine("-------------------------------------------------\n");
      throw e;
   }
}

Public Sub Level2Method()
   Try
      Dim nestedClass As New ClassLevel3

   Catch e As Exception
      Console.WriteLine(" Level2Method exception handler")
      
      ' Display the full call stack at this level.
      Dim st1 As New StackTrace(True)
      Console.WriteLine(" Stack trace for this level: {0}", _
         st1.ToString())

      ' frame and using the next frame.

      Console.WriteLine("-------------------------------------------------")
      Console.WriteLine()
      Throw e
   End Try
End Sub

備註

public StackTrace(System.Diagnostics.StackFrame frame);

new System.Diagnostics.StackTrace : System.Diagnostics.StackFrame -> System.Diagnostics.StackTrace

Public Sub New (frame As StackFrame)

範例

以下程式碼範例將堆疊追蹤資訊寫入事件日誌條目。

StackFrame fr = new StackFrame(1,true);
StackTrace st = new StackTrace(fr);
EventLog.WriteEntry(fr.GetMethod().Name,
                    st.ToString(),
                    EventLogEntryType.Warning);

Dim frame As New StackFrame(1, True)
Dim strace As New StackTrace(frame)            

EventLog.WriteEntry(frame.GetMethod().Name, _
                    strace.ToString(), _
                    EventLogEntryType.Warning)
