股票报价的WebService之四

创建 Web应用程序用户

下面创建一个Web应用程序StockConsumer.ASPx，它作为这个StockQuote（股票报价） Web服务的第一个用户。

＜%@ Page language="C#" %＞

＜%@ Import Namespace="System.XML" %＞

＜%@ Import Namespace="Quotes" %＞

以上引入必要的名称空间。要记住也要引入 Quotes名称空间，它是代理库的名称空间。

＜html＞

＜head＞

＜script runat=server＞

// Wire up the onClick event for a button

protected void button1_Click(object sender, EventArgs e)

{

file://Create a object of the class DailyStock (the proxy class)

DailyStock ds = new DailyStock();

// Call the GetQuote method of the proxy class DailyStock and

// pass the symbol string from the textbox

string res = ds.GetQuote(symbol.Text);

// The returned string has values which are separated

// by commas.

// Hence we split the returned string into parts

char[] splitter = {','} ;

string[] temp = res.Split(splitter);

// Check if the string array returned has more than one

// elements since if there are less than one elements

// then an exception must have been returned

if(temp.Length >1)

{

// The WebService returns a lot of information about the

// stock. We only show the relevant portions

// Set the label to current Index

curindex.Text = "Current Index :"+temp[1];

// Set the label to current Date Time

curdate.Text ="Last Update on"+temp[2]+" at "+temp[3];
