ADO.NET Data Service 访问权限设置

　　很多朋友询问我如何设置ADO.NET Data Service的权限.其实设置ADO.NET Data Service的权限与正常设置ASPNET网站的资源访问权限方式一样.

　　下面我就已ADO.NET Data Service文中的例子为原型,说明一下该如何设置资源访问权限

　　先规划一下ASPNET网站的资源结构

　　在Web.config中按如上设计进行权限配置

<authentication mode="Forms">
<forms name="poweridtag" loginUrl="publicweb/login.aspx" />
</authentication>
<authorization>
<deny users="?">
</deny>
</authorization>
<location path="ClientBin">
<system.web>
<authorization>
<allow users="*">
</allow>
</authorization>
</system.web>
</location>
<location path="publicweb">
<system.web>
<authorization>
<allow users="*">
</allow>
</authorization>
</system.web>
</location>

　　在publicweb中添加一loginService.svc服务,用于提供登录

[ServiceContract(Namespace = "")]
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
public class loginService
{
[OperationContract]
public string login(string userID ,string password)
{
//判断 userID 与 password
System.Web.Security.FormsAuthentication.SetAuthCookie("dbadmin", false);
return "ok";
}
　　
}

　　在SilverlightApplication中添加对loginService.svc服务的引用,并用如下方式完成登录

private void login_Click(object sender, RoutedEventArgs e)
{
loginServer.loginServiceClient lsr = new SilverlightApplication.loginServer.loginServiceClient();
　　
lsr.loginCompleted += new EventHandler<SilverlightApplication.loginServer.loginCompletedEventArgs>(lsr_loginCompleted);
　　
lsr.loginAsync(this.userID.Text,this.password.Text);
　　
}
　　
void lsr_loginCompleted(object sender, SilverlightApplication.loginServer.loginCompletedEventArgs e)
{
if (e.Result == "ok")
{
MessageBox.Show("登录成功");
}
}

　　看一下效果
