如何打印完整的堆栈跟踪异常？ [英] How to print full stack trace in exception?

问题描述

例如，在一个地方...

For example, in one place...

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

...而在另一个地方...

...and in another place...

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

我打印的stacktrace，它只从a开始到b，
它不包括来自WebException的内部stacktrace。

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

我如何打印所有的stacktrace ???

How can I print all the stacktrace???

推荐答案

我通常使用.ToString（）方法来提供异常信息（包括文本中的内部栈跟踪）

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());
}

样本输出：

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
