我正在使用.net并且需要获取一些html文本,所以我想我会一起使用HtmlTextWriter和StringWriter来获得格式正确的html.但是,尽管编写代码的方式各不相同,我仍然会收到静态代码分析器的警告(使用Microsoft All Rules).在下面的代码示例中,我在注释中显示代码分析器警告.为了简化代码,我实际上并没有对HtmlTextWriter进行任何调用(您将在每个函数中看到对该效果的注释).如何正确编写代码以避免警告？

// CA2000 : Microsoft.Reliability : In method 'Default.Func1()', object 'stringWriter' is not disposed along all exception paths. Call System.IDisposable.Dispose on object 'stringWriter' before all references to it are out of scope.
public static string Func1()
{
    string html;
    StringWriter stringWriter;
    using (var writer = new HtmlTextWriter(stringWriter = new StringWriter()))
    {
        // You would do some stuff with the writer here, but not for this example.

        html = stringWriter.ToString();
    }
    return html;
}
