Yes, simple.
say you have

<pre><code>char *a = new char[10];
</code></pre>

writing in the debugger:

<pre><code>a,10
</code></pre>

would show you the content as if it were an array.

I haven't found a way to use this with a multidimensional array. But you can at least (if you know the index of your desired entry) add a watch to a specific value. Simply use the index-operator.

For an Array named current, which has an Array named Attribs inside, which has an Array named Attrib inside, it should look like this if you like to have to position 26:

<pre><code>((*((*current).Attribs)).Attrib)[26]
</code></pre>

You can also use an offset

<pre><code>((*((*current).Attribs)).Attrib)+25
</code></pre>

will show ne "next" 25 elements. 
(I'm using VS2008, this shows only 25 elements maximum).

For example for "CArray pArray", add in the Watch windows

<pre><code> pArray.m_pData,5

to see the first 5 elements .

If pArray is a two dimensional CArray you can look at any of the elements of the second dimension using the next syntax:

a revisit:

let's assume you have a below pointer:

then you can write below in Visual Studio debug watch:

<pre><code>(double(*)[10]) a[0],5

There are two methods to view data in an array m4x4:

<pre><code>float m4x4[16]={
 1.f,0.f,0.f,0.f,
 0.f,2.f,0.f,0.f,
 0.f,0.f,3.f,0.f,
 0.f,0.f,0.f,4.f
};
</code></pre>

One way is with a Watch window (Debug/Windows/Watch). Add watch =

<pre><code>m4x4,16
</code></pre>

This displays data in a list:

<img src="https://i.stack.imgur.com/K54SJ.png" alt="enter image description here">

Another way is with a Memory window (Debug/Windows/Memory). Specify a memory start address = 

<pre><code>m4x4
</code></pre>

This displays data in a table, which is better for two and three dimensional matrices:

<img src="https://i.stack.imgur.com/kBbEI.png" alt="enter image description here">

Right-click on the Memory window to determine how the binary data is visualized. Choices are limited to integers, floats and some text encodings.

In short, you can display a character array as several types of string. If you've got an array declared as:

<pre><code>char *a = new char[10];

You could print it as a unicode string in the watch window with the following:

<pre><code>a,su

See the tables on the MSDN page for all of the different conversions possible since there are quite a few. Many different string variants, variants to print individual items in the array, etc.

If you have a statically allocated array, the Visual Studio debugger can easily display all of the array elements. However, if you have an array allocated dynamically and pointed to by a pointer, it will only display the first element of the array when you click the + to expand it. Is there an easy way to tell the debugger, show me this data as an array of type Foo and size X?

如果您有一个静态分配的数组，Visual Studio调试器可以轻松地显示所有数组元素。但是，如果您有一个动态分配并由指针指向的数组，当您单击+展开它时，它将只显示数组的第一个元素。有没有一种简单的方法来告诉调试器，将这些数据显示为一个类型为Foo、大小为X的数组？
