遇到这样一个怪事：
我的项目所有aspx都包含了menu.html文件，当鼠标移到菜单的左角，再往主页面移时，不管当前显示的是何页面，都会引发如下异常，位置指向Default.aspx.cs的如下代码处：
/**
* 取得单位台帐表中最大的台帐年月
**/
public int GetMaxTZYM()
{
Response.Write("<script>window.alert('" + "GetMaxTZYM" + "')</script>");
//return int.Parse( DBHelp.ExcuteScalar("select max(tzyy*100+tzmm) from dwtz",CommandType.Text,null) );
/**
string str=DBHelp.ExcuteScalar("select max(tzyy*100+tzmm) from dwtz",CommandType.Text,null);
int i=0;
int.TryParse(str,out i);
return i;**/
int i = 0;
string sql = "select max(tzyy*100+tzmm) tzym from dwtz";
DataSet ds = DBHelp.ExcuteDataSet(sql, CommandType.Text, null);
if (ds.Tables[0].Rows.Count > 0)
{
i = int.Parse(ds.Tables[0].Rows[0]["tzym"].ToString());
}
return i;
}
错误总是指向if (ds.Tables[0].Rows.Count > 0)这一行，但奇怪的是没有执行Response.Write("<script>window.alert('" + "GetMaxTZYM" + "')</script>");
重新生成解决方案也没有用。
