我的2005年网站应用在过去两年中是罚款的。 但是,今天,它突然开始将英瓦利德种姓排除在外。
我的法典是:
int DistID = (int) this.Session["DISTRIBUTOR_ID"];
该行的罚款超过两年。
但现在它突然开始放弃无效物的例外情况。 检查方式
this.Session["DISTRIBUTOR_ID"]
had valid int value of 1234.
我通过将我的法典改为:
int DistID = Convert.ToInt32(this.Session["DISTRIBUTOR_ID"]);
But my boss asked me why this error occurred all of a sudden.
谁能回答这个问题?
Convert.ToInt32() function call the parsing function internally but with the first implementation you are using boxing and unboxing. the value in the session should be an integer type when it is assigned.
