Question

我想将Matrix中的数据插入XML。我怎么能这样做？

internal static XDocument createData(string[,] banciforxml)
{
    XDocument Bancile = new XDocument();
    Bancile.Add(new XElement("bancks", 
                             banciforxml.Select(x => new XElement("item", x))));
    return Bancile;
}

Answer 1

你应该这样做：

public XDocument createData(string[,] banciforxml)
{
    XDocument Bancile = new XDocument();

    XElement root = new XElement("banci");

    Bancile.Add(root);

    //Go through the first dimension of the array
    for (int i = banciforxml.GetLowerBound(0); i <= banciforxml.GetUpperBound(0); i++)
    {
        var d1element = new XElement("bancks");

        root.Add(d1element);

        //Go though the second dimension of the array
        for (int j = banciforxml.GetLowerBound(1); j <= banciforxml.GetUpperBound(1); j++)
        {
            var value = banciforxml[i, j];

            if(value == null)
                continue;

            var d2element = new XElement("item" + (j+1));

            d2element.Value = value;

            d1element.Add(d2element);
        }
    }

    return Bancile;
}

此代码使用GetLowerBound和GetUpperBound方法获取数组两个维度中每个维度的下部和上部索引。
