如何查找特定的select xml节点，以及如何通过指定文件路径将该节点另存为另一个xml文件. [英] how to find the specific select xml node and save that node as a another xml file by specifying the file path.

问题描述

受保护的无效test_Click(对象发送者，EventArgs e)
{
XmlDocument Reportxml =新的XmlDocument();
试试
{
//指定要操作的目录.
字符串路径= Server.MapPath("Store/Reports");

试试
{
//确定目录是否存在.
如果(！Directory.Exists(path))
{
//尝试创建目录.
DirectoryInfo di = Directory.CreateDirectory(path);
}
