枚举怎么和数据挂勾呀？
偶还不会用枚举呢，
大家能不能给说说哈
比如，有一个
public   enum   RoleEnum:int
{
DevelopGroupLeader,
DevelopGroupMember,
TestGroupLeader,
TestGroupMember,
DeployGroupLeader,
DeployGroupMember,
                Branch,
ThirdParty
}
user类里的权限判断
public   bool   IsInRole(RoleEnum   role)
{
                        return   ((role   &   _re)==   role);
}
可
private   RoleEnum   _re;
private   User(DataRow   dRows)
{
_AccountName   =   (string)dRows[ "sAMAccountName "];
_Name   =   (string)dRows[ "displayName "];

}

怎么实现呀？


------解决方案--------------------
_re = (RoleEnum)dRows[Role字段名];


另：
return ((role & _re)== role);
=>
return _re == role;
------解决方案--------------------
就是整型的,可以用强制类型转换
