問題XML和數據集

Question

這個問題是最有可能很簡單，但我想提出一個數據集，並嘗試使用的XmlTextWriter

現在，當我救我的數據集將其保存到一個文件，然後嘗試讀取它會讀取表名稱，但顯示行爲0？所以看來我的作家不是在寫表格的行？

任何人都知道我可以解決這個問題嗎？

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(); 
    } 

感謝您對您的幫助提前:)

你正在寫的模式，這是的XML的佈局/結構，而不是實際的內容。

您需要使用DataSet.WriteXml ...
