blocks|key|5264757|text|如果您想同时查看多个元素，可以添加一个逗号和元素的数量：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|5264758|(v._Myfirst)[startIndex],+count|offset|length|style|CODE|5264759|但是，请注意count必须是一个常量，它不能是另一个表达式的结果。|5264760|entityMap^0|0|0|V|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|M|8|@$D|N|E|O|F|G]]|9|@]|A|$]]|$1|H|3|I|5|6|7|P|8|@]|9|@]|A|$]]|$1|J|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|K|$]]

If you want to watch more than one element at the same time, you can append a comma and the number of elements as so:

<code>(v._Myfirst)[startIndex], count</code>

However, note that count must be a constant, it cannot be the result of another expression.

In VS2005 and VS 2008 you can see the contents of STL containers. The rules for getting at the data are in autoexp.dat "c:\Program Files\Microsoft Visual Studio 9\Common7\Packages\Debugger\autoexp.dat". 

AutoExp.dat is meant to be customized. However, the STL defs are under a section called [Visualizer]. If you can figure out the language used in that section, more power to you, however I'd recommend just leaving that part alone.

Autoexp.dat existed in VS2003, but there was no support for STL containers ([Visualizer] didn't exist). In VS2003 you have to manually navigate the underlying data representation.

By modifying autoexp.dat it is possible to add rules for navigating the data representation of your own types so they are easier to debug. If you do this, you should only add to the stuff under [AutoExp]. Be careful and keep a back up of this file before you modify it.

Most simply method is you have to ready a pointer to watch variable like this.

<pre><code>vector&lt;int&gt; a = { 0,1,2,3,4,5 };
int* ptr = &amp;a[0]; // watch this ptr in VisualStudio Watch window like this "ptr,6".
</code></pre>

I tried "a._Myfirst[0]" in VisualStudio2015, But It wasn't display array data.

If you can use "<a href="https://msdn.microsoft.com/en-us/library/jj620914.aspx" rel="nofollow noreferrer">natvis</a>", it will resolve your problems.

This is "sample.natvis" for display std::vector data for Visual studio 2015.

<pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; 
&lt;AutoVisualizer xmlns="http://schemas.microsoft.com/vstudio/debugger/natvis/2010"&gt;
 &lt;Type Name="std::vector&amp;lt;*&amp;gt;"&gt;
 &lt;DisplayString&gt;{{ size={_Mypair._Myval2._Mylast - _Mypair._Myval2._Myfirst} }}&lt;/DisplayString&gt;
 &lt;Expand&gt;
 &lt;Item Name="[size]" ExcludeView="simple"&gt;_Mypair._Myval2._Mylast - _Mypair._Myval2._Myfirst&lt;/Item&gt;
 &lt;Item Name="[capacity]" ExcludeView="simple"&gt;_Mypair._Myval2._Myend - _Mypair._Myval2._Myfirst&lt;/Item&gt;
 &lt;ArrayItems&gt;
 &lt;Size&gt;_Mypair._Myval2._Mylast - _Mypair._Myval2._Myfirst&lt;/Size&gt;
 &lt;ValuePointer&gt;_Mypair._Myval2._Myfirst&lt;/ValuePointer&gt;
 &lt;/ArrayItems&gt;
 &lt;/Expand&gt;
 &lt;/Type&gt;
&lt;/AutoVisualizer&gt;

Visual Studio 2008, at least for me, displays the contents of STL containers in the standard mouseover contents box.

blocks|key|757822|text|您也可以右键单击您的手表中的任何值，并选择“添加手表”。如果您只需要查看map或set的一个元素，这将非常有用。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|757823|它还导致了christopher_f发布的向量的解决方案-((V)._Myfirst)索引|757824|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

You can also right-click any value in your watch, and choose 'add watch'. This can be useful if you only need to look at one element of a map or set. 

It also leads to the solution that christopher_f posted for vectors - ((v)._Myfirst)[index]

blocks|key|757868|text|上面讨论的方法[((v)._Myfirst)index]只适用于特定的容器(std：：vector)，而不是所有可能的STL容器。例如，如果您想查看std::deque的内容，那么您必须寻找一些其他方法来浏览std::deque中的内容。|type|unstyled|depth|inlineStyleRanges|offset|length|style|BOLD|entityRanges|data|757869|也许您可以尝试以下类似的设置来解决您的问题|757870|我仅针对随Microsoft+Visual+Studio+2010+Service+pack+1安装的Visual+Studio2010专业版测试了此设置|757871|步骤1:卸载Microsoft+Visual+studio+2010Service+pack+1-对于我的项目工作，我并不真正需要Service+pack+1，因此卸载Service+pack+1不会对我的情况造成任何问题。|757872|步骤2:重新启动系统。|757873|步骤3:如果你没有得到错误'LINK+:+fatal+Error+LNK1123:+failure+during+COFF:+file+invalid+or+COFF‘，这一步是不必要的。否则，请浏览|757874|项目属性->链接器(常规)+->更改启用增量链接为否(/INCREMENTAL:NO)|757875|entityMap^0|7|L|0|0|0|1C|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|T|8|@$9|U|A|V|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|W|8|@]|D|@]|E|$]]|$1|H|3|I|5|6|7|X|8|@$9|Y|A|Z|B|C]]|D|@]|E|$]]|$1|J|3|K|5|6|7|10|8|@]|D|@]|E|$]]|$1|L|3|M|5|6|7|11|8|@]|D|@]|E|$]]|$1|N|3|O|5|6|7|12|8|@]|D|@]|E|$]]|$1|P|3|Q|5|6|7|13|8|@]|D|@]|E|$]]|$1|R|3|-4|5|6|7|14|8|@]|D|@]|E|$]]]|S|$]]

Above discussed method [((v)._Myfirst)[index]] will work only for specific container(std::vector) not for all possible STL containers. For example if you want to see the content of std::deque then you have to look for some other method to browse through the content in std::deque.

Maybe you can try the following similar setting to solve your issue 

[I tested this setting only for Visual Studio 2010 Professional version installed with Microsoft Visual studio 2010 Service pack 1]

Step 1: Uninstall the Microsoft Visual studio 2010 Service pack 1 - for my project work I don't really need the Service pack 1 so uninstalling service pack 1 will not cause any issue for my case.

Step 2: Restart your system.

Step 3: This step is not necessary if you are not getting Error 'LINK : fatal error LNK1123: failure during conversion to COFF: file invalid or corrupt'. Otherwise browse through

In vs 2015, I could not get any of these working 
so, i wrote a bit of code

<pre><code>std::vector&lt;std::string&gt; vs(M_coins + 1);
for (unsigned long long i = 0; i &lt;= M_coins; i++) {
 std::for_each(memo[i].begin(), memo[i].end(), [i, &amp;vs](long long &amp;n) {
 vs[i].append(std::to_string(n));
 });
}
// now vs is ready for use as vs[0], vs[1].. so on, for your debugger
</code></pre>
basically what i did was converted vector into string.
i had vector of vector so i had string vector to fill.
<h1>2: if you have just a vector of long long elements, then just convert as below:</h1>
<pre><code>std::vector&lt;std::string&gt; s;
std::for_each(v1.begin(), v1.end(), [&amp;s](long long &amp;n) {
 s.append(std::to_string(n));
 });
// now s is ready for use, for your debugger
</code></pre>
hope it helped.

This is old but since I regularly stumble on this post because it is still referenced high on google, as of Visual Studio 2019, one can simply write in the debugger's Watch:
<pre><code>vectorName.data()
</code></pre>
(replace vectorName by your variable name) to get a pointer to the content.
Then, knowing the current size of the vector, you can tell the debugger to show you the first N cells:
<pre><code>vectorName.data(),N
</code></pre>
(N being the size of your vector)
And if like me, you have a lot of vectors of bytes that actually store another data structure, you can even tell the debugger to interpret the pointer as an array of something else :
<pre><code>(float*)vectorName.data(),4
</code></pre>
For example, I have a std::vector of 16 bytes and using that I can tell the debugger to show me an array of 4 floats instead (which is more useful to me than the bytes alone).

If I have a <code>std::vector</code> or <code>std::map</code> variable, and I want to see the contents, it's a big pain to see the nth element while debugging. Is there a plugin, or some trick to making it easier to watch STL container variables while debugging <code>(VS2003/2005/2008)</code>?

如果我有一个std::vector或std::map变量，并且我希望看到它的内容，那么在调试时看到第n个元素是一件非常痛苦的事情。在调试(VS2003/2005/2008)时，有没有什么插件或者技巧可以让你更容易观察STL容器变量？
