向大神求助 “System.AccessViolationException”类型的未经处理的异常在 System.Data.dll 中发生
调试的时候突然之间一连数据库就崩, 结果把连接单拉出来试试还是不行.我查了一下都说是代码的问题,可是我单独就写一句连接还是报错,不知道怎么解决,向大神求助啊!!!
代码就这一块
 SqlConnection con = new SqlConnection("Data Source=192.168.***.***;Initial Catalog=******;Password=***;Persist Security Info=FALSE;User ID=***");
            try
            {
                con.Open();
            }
