"SendFlag"(参数)是返回FLASH作判断的:
单独运行的时候:
编译器错误信息: BC30109: String is a class type, and so is not a valid expression.
也就是这样的格式: string sID=Request["idNumber"],SendFlag; 有错误的了.
代码的格式不对了.应该怎样表达呢?
网友回答：
string sID=Request["idNumber"],SendFlag
如果你想声明两个字符串变量
你可以
string sID=Request.QueryString["idNumber"]; //这样写试试
string SendFlag;
按楼上的做一下试试
