如何在异常中打印完整的堆栈跟踪?

发布于 2024-10-04 06:25:47 字数 459 浏览 2 评论 0原文

例如,在一个地方......

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

而在另一个地方......

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

我打印的堆栈跟踪,它只从a开始到b, 它不包括来自 WebException 的内部堆栈跟踪。

我怎样才能打印所有的堆栈跟踪???

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???

我通常对异常使用 .ToString() 方法以文本形式显示完整的异常信息(包括内部堆栈跟踪):

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

示例输出:

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

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

使用这样的函数:

    public static string FlattenException(Exception exception)
    {
        var stringBuilder = new StringBuilder();

        while (exception != null)
        {
            stringBuilder.AppendLine(exception.Message);
            stringBuilder.AppendLine(exception.StackTrace);

            exception = exception.InnerException;
        }

        return stringBuilder.ToString();
    }

然后你可以这样调用它:

try
{
    // invoke code above
}
catch(MyCustomException we)
{
    Debug.Writeline(FlattenException(we));
}

Use a function like this:

    public static string FlattenException(Exception exception)
    {
        var stringBuilder = new StringBuilder();

        while (exception != null)
        {
            stringBuilder.AppendLine(exception.Message);
            stringBuilder.AppendLine(exception.StackTrace);

            exception = exception.InnerException;
        }

        return stringBuilder.ToString();
    }

Then you can call it like this:

try
{
    // invoke code above
}
catch(MyCustomException we)
{
    Debug.Writeline(FlattenException(we));
}

1.创建方法:如果您将异常传递给以下函数,它将为您提供所有方法和详细信息,这些方法和详细信息是异常原因。

public string GetAllFootprints(Exception x)
{
        var st = new StackTrace(x, true);
        var frames = st.GetFrames();
        var traceString = new StringBuilder();

        foreach (var frame in frames)
        {
            if (frame.GetFileLineNumber() < 1)
                continue;

            traceString.Append("File: " + frame.GetFileName());
            traceString.Append(", Method:" + frame.GetMethod().Name);
            traceString.Append(", LineNumber: " + frame.GetFileLineNumber());
            traceString.Append("  -->  ");
        }

        return traceString.ToString();
}

2.调用方法:可以这样调用方法。

try
{
    // code part which you want to catch exception on it
}
catch(Exception ex)
{
    Debug.Writeline(GetAllFootprints(ex));
}

3.获取结果:

File: c:\MyProject\Program.cs, Method:MyFunction, LineNumber: 29  -->  
File: c:\MyProject\Program.cs, Method:Main, LineNumber: 16  --> 

1. Create Method: If you pass your exception to the following function, it will give you all methods and details which are reasons of the exception.

public string GetAllFootprints(Exception x)
{
        var st = new StackTrace(x, true);
        var frames = st.GetFrames();
        var traceString = new StringBuilder();

        foreach (var frame in frames)
        {
            if (frame.GetFileLineNumber() < 1)
                continue;

            traceString.Append("File: " + frame.GetFileName());
            traceString.Append(", Method:" + frame.GetMethod().Name);
            traceString.Append(", LineNumber: " + frame.GetFileLineNumber());
            traceString.Append("  -->  ");
        }

        return traceString.ToString();
}

2. Call Method: You can call the method like this.

try
{
    // code part which you want to catch exception on it
}
catch(Exception ex)
{
    Debug.Writeline(GetAllFootprints(ex));
}

3. Get the Result:

File: c:\MyProject\Program.cs, Method:MyFunction, LineNumber: 29  -->  
File: c:\MyProject\Program.cs, Method:Main, LineNumber: 16  -->

推荐使用LINQPad相关的nuget包,然后就可以使用exceptionInstance.Dump()

输入图片此处描述

对于 .NET core:

  • 安装 LINQPad.Runtime

对于 .NET Framework 4 等。

  • 安装 LINQPad

示例代码:

using System;
using LINQPad;

namespace csharp_Dump_test
{
    public class Program
    {
        public static void Main()
        {
            try
            {
                dosome();
            }
            catch (Exception ex)
            {
                ex.Dump();
            }
        }

        private static void dosome()
        {
            throw new Exception("Unable.");
        }
    }
}

运行结果:< /强>

LinqPad nuget 包是打印异常堆栈信息的最棒的工具。

                ex.Dump();
            }
        }

        private static void dosome()
        {
            throw new Exception("Unable.");
        }
    }
