前面介绍了微活动《大转盘》 和 《刮刮卡》，这次介绍下微投票，微投票分二种，一种是文本投票， 一种是图片投票。
下面介绍文本投票的详细步骤：

}

context.Response.Write(MyCommFun.getJsonStr(jsonDict));
}
}
public bool IsReusable
{
get
{
return false;
}
}
}
因为前面设置的是投票完成后才可以看到投票结果，所以这里投完票后会显示投票的结果
protected float computeBL(int ttCount, int itemCount)
{
if (ttCount == 0)
{
return (float)0.00;
}
float ret = (itemCount * 100.0f) / ttCount;
ret = (float)Math.Round(ret, 2);
return ret;
}
