将 XML 输出到数据集

Question

我一直在尝试从外部源读取 xml 文件以将其放入数据集。我采用了架构并通过 xsd 编译了我的类并将其加载到解决方案中。

我的 xml：

<?xml version="1.0" encoding="UTF-8" standalone="true"?>

我似乎无法将此 xml 列出或放入数据集中。我是反序列化 xml 的新手，可以使用一些帮助。

只需使用文件路径调用 ReadXml：

var dataSet = new DataSet();
dataSet.ReadXml(string PathToFile);

效果很好；甚至会创建所有关系（请注意屏幕截图中的CAMDealerManifestId）。

您的文件只对 XML 声明进行了修改——必须将 standalone 值从 true 更改为 yes：

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>

如果您将其作为字符串读取，则可以执行以下操作：

var xmlString = HoweverYouGetTheString().Split(new string[] { "\r\n" }, StringSplitOptions.None);
xmlString[0] = "<?xml version=\"1.0\" encoding=\"UTF-8\" standalone=\"yes\"?>";

using (var reader = new System.IO.StringReader(String.Join("\r\n", xmlString)))
{
    dataSet.ReadXml(reader);
}
