这是一个写XML的例子,如果App_Data中没有NewBook.xml则创建一个,然后把下图中内容保存到NewBook.xml
1.xml文件
<?xml version='1.0'?><!-- This file represents a fragment of a book store inventory database --><bookstore><book genre="autobiography"><title>The Autobiography of Benjamin Franklin</title><author><first-name>Benjamin</first-name><last-name>Franklin</last-name></author><price>8.99</price></book><book genre="novel"><title>The Confidence Man</title><author><first-name>Herman</first-name><last-name>Melville</last-name></author><price>11.99</price></book><book genre="philosophy"><title>The Gorgias</title><author><name>Plato</name></author><price>9.99</price></book></bookstore>2.xmlReadWriteOperation.aspx
