Asp.net Development (User Group Management), asp.net Group

The previous article explains how to create a user group and move users to a group. This chapter describes how to modify the group name and delete a group.

Directly code the object class that is required to obtain the group list.

/// <Summary> /// group class /// </summary> public class WxGroupsInfo {public string Group_ID {get; set ;} // Group No. public string Group_Name {get; set;} // group name public string Group_Count {get; set;} // group count}

The background code is as follows:

The above is all the core code of user group management. It is for your reference only and I hope it will be helpful for your learning.
