使用说明和关闭方法 [英] Using statement and Close methods

问题描述

难道using语句真正调用close方法与数据库连接对象使用时？ MSDN文档说，这可以确保调用Dispose方法，但并没有提及接近。我看到堆栈溢出的帖子里的人说，它确实两者兼而有之。是否有人有一个具体的答案一对这个来自微软或其他确凿的证据拉上它呢？

Does the using statement really call the close method when used with a database connection object? The MSDN documentation says it ensures that the Dispose method is called but makes no mention of close. I see posts on Stack Overflow where people say that it does both. Does someone have a concrete answer one way or another on this from Microsoft or other solid proof that it does?

推荐答案

下面是SqlConnection类的处置的方法：

Here is the "Dispose" method of the SqlConnection class:

protected override void Dispose(bool disposing)
{
    if (disposing)
    {
        this._userConnectionOptions = null;
        this._poolGroup = null;
        this.Close();
    }
    this.DisposeMe(disposing);
    base.Dispose(disposing);
}

正如你所看到的，它确实调用close（）

As you can see, it does indeed call Close()
