键盘输入12,23,34,45，即字符串以逗号分隔，用split方法拆分为数据，帮助中有例子，简单修改即可。建立数组，如只有26个字母，则维数26，循环字符串，用switch判断第几个字母，并在对应的数据中加1，显示时，为0的数组数据不显示，显示的第几维，则字母就是第几个。如果是中文判断，要使用动态数据arraylist。C#数组有4种写法ArrI=new Array();ArrI[0] = new Array("username1","0","609");ArrI[1] = new Array("username2","609","610");ArrI[2] = new Array("username3","609","611");ArrII=new Array();new Array("username1","0","609"),new Array("username2","609","610"),new Array("username3","609","611")ArrIII=[];ArrIII[0] = new Array("username1","0","609");ArrIII[1] = new Array("username2","609","610");ArrIII[2] = new Array("username3","609","611");ArrIIII=[];["username1","0","609"],["username2","609","610"],["username3","609","611"]
