代码创建自定义权限级别

原文地址 : http://www.cnblogs.com/Kenr/archive/2009/04/02/1428240.html

在MOSS页面上设置自定义权限级别，可以进入以下页面进行操作

1. 在“网站设置”页上的“用户和权限”下，单击“高级权限”。
2. 在工具栏上，单击“设置”，然后单击“权限级别”。

代码实现：

using (SPWeb oWebsite = SPContext.Current.Site.AllWebs["Subsite_Name"])

{

    SPRoleDefinitionCollection collRoles = oWebsite.RoleDefinitions;

//取得名为【Definition_Name】的自定义权限级别

    SPRoleDefinition oRoleDefinition = collRoles["Definition_Name"];

//定义【Definition_Name】所拥有的权限

    oRoleDefinition.BasePermissions = SPBasePermissions.FullMask ^

        SPBasePermissions.ManagePermissions;

//不要忘记更新

    oRoleDefinition.Update();

}

代码解析：

（1）当给自定义权限级别添加基本权限时，可以使用以下符号

• & - bitwise AND
• ^ - exclusive OR
• | - inclusive OR

例：

1) oRoleDefinition.BasePermissions |= SPBasePermissions.ManageSubwebs;

Retains the current permissions mask but adds ManageSubwebs to the mask.

2) oRoleDefinition.BasePermissions ^= SPBasePermissions.CreateSSCSite;

Retains the current permissions mask but removes CreateSSCSite from the mask.

3) oRoleDefinition.BasePermissions &= SPBasePermissions.CreateAlerts;

Reduces the permissions mask so that it only contains CreateAlerts.

（2）下面是能够在自定义权限级别里添加的基本权限一览
