c# - Xml 和数据集的问题

Question

这个问题很可能非常简单，但我正在制作一个数据集并尝试使用 XMLTextWriter 将其保存到文件

现在，当我保存数据集然后尝试读取它时，它会读取表名称，但将行显示为 0？所以看来我的作者没有写表格的行？

有人知道我该如何解决这个问题吗？

public static DataSet liveData = new DataSet();

    public static DataTable players = new DataTable("Players");

public static void WriteSchemaWithXmlTextWriter()
    {
        // Set the file path and name. Modify this for your purposes. 
        string filename = "Schema.xml";

        // Create a FileStream object with the file path and name.
        System.IO.FileStream stream = new System.IO.FileStream(filename, System.IO.FileMode.Create);

        // Create a new XmlTextWriter object with the FileStream.
        System.Xml.XmlTextWriter writer = new System.Xml.XmlTextWriter(stream, System.Text.Encoding.Unicode);

        // Write the schema into the DataSet and close the reader.
        liveData.WriteXmlSchema(writer);
        writer.Close();
    }

    public static void ReadSchemaFromXmlTextReader()
    {
        // Set the file path and name. Modify this for your purposes. 
        string filename = "Schema.xml";

        // Create a FileStream object with the file path and name.
        System.IO.FileStream stream = new System.IO.FileStream(filename, System.IO.FileMode.Open);

        // Create a new XmlTextReader object with the FileStream.
        System.Xml.XmlTextReader xmlReader = new System.Xml.XmlTextReader(stream);

        // Read the schema into the DataSet and close the reader.
        liveData.ReadXmlSchema(xmlReader);
        Console.WriteLine("y: {0}", liveData.Tables["Players"].Rows.Count);
        xmlReader.Close();
    }

感谢您提前提供的帮助:)

您正在编写架构，即 Xml 的布局/结构，而不是实际内容。

您需要使用DataSet.WriteXml ...
