个人记录：判断用户组是否存在

SharePoint 2007不存在判断用户组isExist的方法，因此只有自己写一个喽：

 

public static bool GroupExists(SPGroupCollection groups, string name)

{

if (string.IsNullOrEmpty(name) ||

(name.Length > 255) ||

(groups == null) ||

(groups.Count == 0))

return false;

else

return (groups.GetCollection(new String[] { name }).Count > 0);

}

public static bool GroupExists(SPGroupCollection groups, int id)

{

if ((id < 0) ||

(groups == null) ||

(groups.Count == 0))

return false;

else

return (groups.GetCollection(new Int32[] { id }).Count > 0);

}
