微信自定义菜单这个就比较简单，直接贴代码。
微信说的注意：
目前自定义菜单最多包括3个一级菜单，每个一级菜单最多包含5个二级菜单。一级菜单最多4个汉字，二级菜单最多7个汉字，多出来的部分将会以“...”代替。请注意，创建自定义菜单后，由于微信客户端缓存，需要24小时微信客户端才会展现出来。建议测试时可以尝试取消关注公众账号后再次关注，则可以看到创建后的效果。
#region 菜单管理
public ActionResult CreateMenu()
{
string access_token = weixin.AccessToken();
string url = "https://api.weixin.qq.com/cgi-bin/menu/create?access_token=" + access_token;
string data = "";
using (StreamReader sr = new StreamReader(Server.MapPath("/Config/menu.txt")))
{
data = sr.ReadToEnd();
}
var json = HttpHelper.Post(url, data);
return Content(json);

{
