Question

我编写了以下代码，它读取给定的xml文件并将内容写入数据表。请不要建议使用LinqToXml，因为这是一个遗留应用程序。

            // create the DataTable that will hold the data
            DataTable table = new DataTable("ListOfPersonsWithInfo");


            // open the file using a Stream
            using (Stream stream = new FileStream(fileNameWithAbsolutePath, FileMode.Open, FileAccess.Read))
            {
                // create the table with the appropriate column names
                table.Columns.Add("Name", typeof(String));
                table.Columns.Add("ImagePath", typeof(String));
                table.Columns.Add("Address", typeof(String));

                // use ReadXml to read the XML stream
                table.ReadXml(stream);

                // tried with this overload-option as well but didnt help
                //table.ReadXml(fileNameWithAbsolutePath);

                // return the results
                return table;
            }

但是返回的表包含ZERO行...... !!!实际的xml文件在哪里有'3行'，结构如下（任何IDEA这里出了什么问题？）：

<?xml version="1.0" encoding="utf-8"?>
<Details>
    <EachPerson>
        <Name>Jack</Name>
        <ImagePathAndFileName>C:\Users\Public\Pictures\Sample Pictures\Desert.jpg</ImagePathAndFileName>
        <Address>NewYork</Address>
    </EachPerson>
    <EachPerson>
        <Name>Tom</Name>
        <ImagePathAndFileName>C:\Users\Public\Pictures\Sample Pictures\Desert.jpg</ImagePathAndFileName>
        <Address>London</Address>
    </EachPerson>
    <EachPerson>
        <Name>Jill</Name>
        <ImagePathAndFileName>C:\Users\Public\Pictures\Sample Pictures\Desert.jpg</ImagePathAndFileName>
        <Address>Tokyo</Address>
    </EachPerson>
</Details>

Answer 1

您可以使用ReadXML

        DataSet ds = new DataSet();
        ds.ReadXml(fileNameWithAbsolutePath);
        return ds.Tables[0];

用于将XML文件读入DataTable的代码
