在Windbg中，如何从！do命令获取全部内容 [英] In Windbg how to get the whole content from !do Command

问题描述

我目前正在处理.NET应用程序中的内存问题，我正在使用Windbg调试问题，我发现了内存问题是什么，但是在调查期间!do命令正在为我获取对象内容过大，但是该命令显示的内容被截断了，有没有办法我可以从!do命令完全获取其内容?

I'm currently working in a memory issue on a .NET application, I'm debugging the Issue using Windbg I have come across to what the memory issue is, but during the investigation !do command is getting me the object which has a content that is excessive large BUT the Content that gets displayed by the command is truncated, Is there a way that I can get the Content in its entirely from the !do command?

命令的结果如下所示:

0:000> !do [Address]
Name:        System.Byte[]
MethodTable: ...
EEClass:     ...
Size:        1048600(0x100018) bytes
Array:       Rank 1, Number of elements 1048576, Type Byte
Content:     [This is the content that its getting truncated]
Fields:
None

推荐答案

由于具有byte数组，因此可以使用db转储原始内存.我创建了一个值为0、1、2，... 2000的byte数组，并将其转储出去:

Since you have a byte array you can use db to dump out the raw memory. I created a byte array with values 0, 1, 2, ... 2000 and dumped it out:

0:000> !do 0x020a3560
Name:        System.Byte[]
MethodTable: 73504588
EEClass:     7319229c
Size:        2012(0x7dc) bytes
Array:       Rank 1, Number of elements 2000, Type Byte
Content:     ................................ !"#$%&'()*+,-./0123456789:;?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`abcdefghijklmnopqrstuvwxyz{|}~.
Fields:
None

前4个字节是方法表(73504588)，后4个字节是数组的长度(0x07D0或0n2000).那么之后的所有字节就是数据.

The first 4 bytes are the method table (73504588), and the next 4 bytes are the length of the array (0x07D0, or 0n2000). Then all the bytes after that are the data.
