我正在做一个项目，在该项目中，我从 c# 创建了一个 power point 文档。由于某种原因，在我的一种方法上，一切都很好，但我收到了这个错误：

“处于 EndRootElement 状态的令牌 StartElement 将导致无效的 XML 文档。”

这是我的方法：

        FileStream slideLayout6Stream = new FileStream( slideLayout6, FileMode.Create, FileAccess.Write );
        XmlWriter slideLayout6Writer = null;

        try
        {
            XmlWriterSettings contentTypesSettings = new XmlWriterSettings();
            contentTypesSettings.Indent = true;
            slideLayout6Writer = XmlWriter.Create( slideLayout6Stream, contentTypesSettings );

            slideLayout6Writer.Close();
        }
    }

对不起，大规模的方法，但在这种方法中，它会引发错误。任何帮助将不胜感激谢谢。

我的猜测是你已经关闭了最外层的元素，所以你不能打开一个新的，因为 XML 只允许最外层的一个元素。

这种接口对于编写 XML 非常方便，我自己也使用它，但是如果你犯了任何嵌套错误，它可能会很麻烦。众所周知，我对接口使用自己的包装器，其中对 endElement 的调用必须指定匹配的标签名称；然后包装器可以检查调用的正确嵌套，这极大地有助于识别错误所在。

你调用 startelement 81 次......猜猜看：你没有调用 endelement 81 次......

所以确保开始和结束正确匹配;）
