谁能解释下这段代码（关于StackTrace）
using System;
using System.Diagnostics;
class StackTraceSample
{
[STAThread]
static void Main(string[] args)
{
StackTraceSample sample = new StackTraceSample();
try
{
sample.MyPublicMethod();
}
catch (Exception)
{
// Create a StackTrace that captures
// filename, line number, and column
// information for the current thread.
StackTrace st = new StackTrace(true);
for(int i =0; i< st.FrameCount; i++ )
{
// Note that high up the call stack, there is only
// one stack frame.
StackFrame sf = st.GetFrame(i);
Console.WriteLine();
Console.WriteLine("High up the call stack, Method: {0}",
sf.GetMethod());
Console.WriteLine("High up the call stack, Line Number: {0}",
sf.GetFileLineNumber());
}
}
}
public void MyPublicMethod ()
{
MyProtectedMethod();
}
protected void MyProtectedMethod ()
{
MyInternalClass mic = new MyInternalClass();
mic.ThrowsException();
}
class MyInternalClass
{
public void ThrowsException()
{
try
{
throw new Exception("A problem was encountered.");
}
catch (Exception e)
{
// Create a StackTrace that captures filename,
// line number and column information.
StackTrace st = new StackTrace(true);
string stackIndent = "";
for(int i =0; i< st.FrameCount; i++ )
{
// Note that at this level, there are four
// stack frames, one for each method invocation.
StackFrame sf = st.GetFrame(i);
Console.WriteLine();
Console.WriteLine(stackIndent + " Method: {0}",
sf.GetMethod() );
Console.WriteLine( stackIndent + " File: {0}",
sf.GetFileName());
Console.WriteLine( stackIndent + " Line Number: {0}",
sf.GetFileLineNumber());
stackIndent += " ";
}
throw e;
}
}
}
}
补充：.NET技术 , C#
