如何在静态方法中调用void函数（非静态方法）....



我在json保存后有一个名为drawmenu的函数（webmethod c＃）它应该被称为......怎么可能？我希望在保存后刷新我的菜单列表，不用回帖....

无效drawMenu（）

string str = select query

SqlDataAdapter sqladp = new SqlDataAdapter（str，Conn）;

DataTable dt = new DataTable（）;

sqladp.Fill（dt ）;

{

InnerHTML =我的查询数据< br $>

divmenu.InnerHtml = InnerHTML;

}



DivMenu是我的Div ...



[WebMethod]

public static string Update（string CAT_ID，string CAT_NAME，string DESCRIPTION，string PID）

{

var UID = int.Parse（CAT_ID）;

var UPID = int.Parse（PID）;

string retMessage = string.Empty;

DATABASE db = new DATABASE（）;

var empQuery =来自CAT中的t

其中（t .CAT_ID == UID）

选择t;

CAT obj = empQuery.Single（）;

obj.CAT_NAME = CAT_NAME;

obj.DESCRIPTION = DESCRIPTION;

obj.PID = UPID;

db.SaveChanges（）;

返回retMessage;

}
