For example, in one place...

//---------------a
try
{
    // some network call
}
catch(WebException we)
{
    throw new MyCustomException("some message ....", we);
}

...and in another place...

//--------------b
try
{
    // invoke code above
}
catch(MyCustomException we)
{
    Debug.Writeline(we.stacktrace);   // <----------------
}

The stacktrace I print, it only start from a to b, it doesnt include the inner stacktrace from the WebException.

How can I print all the stacktrace???

I usually use the .ToString() method on exceptions to present the full exception information (including the inner stack trace) in text:

catch (MyCustomException ex)
{
    Debug.WriteLine(ex.ToString());
}

Sample output:

ConsoleApplication1.MyCustomException: some message .... ---> System.Exception: Oh noes!
   at ConsoleApplication1.SomeObject.OtherMethod() in C:\ConsoleApplication1\SomeObject.cs:line 24
   at ConsoleApplication1.SomeObject..ctor() in C:\ConsoleApplication1\SomeObject.cs:line 14
   --- End of inner exception stack trace ---
   at ConsoleApplication1.SomeObject..ctor() in C:\ConsoleApplication1\SomeObject.cs:line 18
   at ConsoleApplication1.Program.DoSomething() in C:\ConsoleApplication1\Program.cs:line 23
   at ConsoleApplication1.Program.Main(String[] args) in C:\ConsoleApplication1\Program.cs:line 13
