在C ++ / .NET中使用SqlConnection [英] using a SqlConnection in C++ / .NET

问题描述

当我访问 MSDN 页面为 SqlConnection 类，它只显示了C＃和VB中的示例。为什么MSDN不显示C ++示例？

When I go to the MSDN page for the SqlConnection class, it only shows examples in C# and VB. Why doesn't MSDN show a C++ example?

我特别感兴趣的是C ++示例如何解决 code> C ++中的关键字。

I am particularly interested in how a C++ example would get around the lack of the using keyword in C++.

推荐答案

Hmmm ...在阅读什么是Managed C ++等同于C＃using语句。相当于：

Hmmm... after reading What is the Managed C++ equivalent to the C# using statement it seems that the equivalent of:

using (SqlConnection connection = new SqlConnection(connectionString))
{
    // SqlCommand and so...
}

实际上是：

{
  SqlConnection conn(connectionString);

  // SqlCommand and so...
}

这是相当令人印象深刻的，因为C ++不缺少使用语句，因为它完全不需要它！我不认为C＃/ VB程序员充分认识到C ++的优势（我当然没有:)。

That is quite impressive, since C++ does not "lack" theusing statement as much as it removes the need for it entirely! I don't think that C#/VB programmers sufficiently appreciate that advantage of C++ (I certainly didn't :) .
