string iRole = Session["module"].ToString();
XmlDataSource xmlDS = new XmlDataSource();
xmlDS.DataFile = xmlPath;
xmlDS.XPath = "Home/Role[@id='" + iRole + "']";
Menu1.DataSource = xmlDS;
Menu1.DataBind();
Menu1.Items[0].Text = "";
Menu1.Items[0].Value = "";
Menu1.Items[0].Selectable = false;
}
}

请告诉我如果用户具有多个角色该如何启用菜单

推荐答案
请告诉我如果用户具有多个角色该如何启用菜单
根据当前的设计，更倾向于假设一个人将扮演一种角色.因此，即使为您的多用户方案更改代码是可能的，但这也是一种解决方法.现在，在这里考虑两个角色:
1.您可以使用所有可能的组合在XML中定义新角色.如RoleId =''PMGT | WDS''.使用XPath，找到角色，一旦找到完全匹配的内容，就使用该节点.您可以根据需要使用任何定界符(例如RoleId ="PMGT，WDS").
2.否则，您可以为找到的第一个角色添加菜单项，然后继续进行更多角色比较，直到菜单xml结束.只要找到匹配的角色，就继续添加菜单项.

Based on the current design, it is more towards assumption that one person will have one role. So even though changing code for your multi user scenario is possible but would be a workaround. Now, for considering two roles here:
1. Either you can define new roles in XML with all possible combination. Like RoleId=''PMGT|WDS''. Using XPath, find the role and once you find the exact match use that node. You can use any delimiter as per your wish (Like RoleId=''PMGT,WDS'').
2. Or else you can add menu items for first role found and then move on with more role comparison till the end of menu xml. As long as you find a role match keep adding the menu items.
