Sponsorlu Bağlantılar

This example shows how to get call stack in .NET. Call stack is represented by StackTraceclass and a method call is represented by StackFrame class. You can get the frames usingStackTrace.Get­Frames method. It returns array of frames. Frame with index 0 is current executing method, frame 1 is calling method, next frame is its caller and so on.

Following example writes call stack method names. It creates an instance of StackTrace (call stack), gets all frames (method calls) and writes the method names.

[C#]

using System.Diagnostics;

[STAThread]
public static void Main()
{
  StackTrace stackTrace = new StackTrace();           // get call stack
  StackFrame[] stackFrames = stackTrace.GetFrames();  // get method calls (frames)

  // write call stack method names
  foreach (StackFrame stackFrame in stackFrames)
  {
    Console.WriteLine(stackFrame.GetMethod().Name);   // write method name
  }
}

The output is:

Main
