问题描述

Visual Studio如何在C ++中显示向量的元素或字符串的字符？

How does Visual Studio show the elements of a vector, or the characters of a string, in C++? Is there a way for me to make it show my own classes in a custom way?

对于本机代码，您可以将自定义数据类型扩展添加到文件
autoexp.dat，它位于Program Files \ Microsoft Visual
Studio 10.0 \Common7 \Packages\Debugger目录中。

For native code, you can add custom data type expansions to the file autoexp.dat, which is located in the Program Files\Microsoft Visual Studio 10.0\Common7\Packages\Debugger directory. Instructions on how to write autoexp rules are located in the file itself.

对于这个类：

template<class T>
struct  auto_array {
     T* data;
     int Len;
};

autoexp.data可能如下所示：

the autoexp.data might look like:

auto_array<*> {
    children
    (
        #array
        (
            expr :      $e.Data[$i],
            size :      $e.Len
        )
    )
    preview
    (
        #(
            "[", $e.Len , "](",
            #array
            (
                expr :  $e.Data[$i],
                size :  $e.Len
            ),
            ")"
        )
    )
}
