在silverlight往往还是有一些获取不到的东西,比如说客户机的ip等的数据.可以通过初始化sl时把参数传入sl中.
1.修改page类
2.修改App.xaml.cs
private
void
Application_Startup(
object
sender, StartupEventArgs e)
{
// Load the main control
string passtext = e.InitParams[ " passtext " ];
this .RootVisual = new Page(passtext);
}
{
// Load the main control
string passtext = e.InitParams[ " passtext " ];
this .RootVisual = new Page(passtext);
}
3.传递参数
- 方法1:
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
<%@ Register Assembly="System.Web.Silverlight" Namespace="System.Web.UI.SilverlightControls"
TagPrefix="asp" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>passtxt</title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<div style="height: 100%;">
<asp:Silverlight ID="Xaml1" runat="server" Source="~/ClientBin/HowTo.xap" Version="2.0"
Width="100%" Height="100%"/>
</div>
</div>
</form>
</body>
</html>
- 方法2:
< object data ="data:application/x-silverlight," type ="application/x-silverlight-2-b1" InitParameters ="passtext=123" width ="100%" height ="100%" >
< param name ="InitParams" value ="passtext=参数_方法2" />
< param name ="source" value ="ClientBin/HowTo.xap" />
< param name ="onerror" value ="onSilverlightError" />
< param name ="background" value ="white" />
< a href ="http://go.microsoft.com/fwlink/?LinkID=108182" style ="text-decoration: none;" >
< img src ="http://go.microsoft.com/fwlink/?LinkId=108181" alt ="Get Microsoft Silverlight" style ="border-style: none" />
</ a >
</ object >
传递多个参数也是一样的.定义的时候改一下.后边的方法也类似.
public
Page(
string
passtext1,
string
passtext2)
{
InitializeComponent();
txtPass1.Text = passtext1;
txtPass2.Text = passtext2;
}
{
InitializeComponent();
txtPass1.Text = passtext1;
txtPass2.Text = passtext2;
}
参数间用","隔开
ok 获取参数完成 ;)附录:获取客户机ip "System.Net.Dns.GetHostAddresses(System.Net.Dns.GetHostName()).GetValue(0).ToString();"
