超极郁闷的SqlCommand语句...
SqlCommand   Sc   =   new   SqlCommand();
SqlDataReader   query;
string   mysql1   =   "select   max(userid)   as   val   from   smt_companyuser ";
Sc.CommandText   =   mysql1;
query   =   Sc.ExecuteReader();
query.Read();

当程序执行到query   =   Sc.ExecuteReader();   就不执行下面任何语句了,,,也不报任何错误....  
各位大哥指教指教


------解决方案--------------------
刚发错了，应该是
SqlConnection conn=new SqlConnection( "server=.;database=;uid=sa;pwd= ");
SqlCommand Sc = new SqlCommand(conn);
------解决方案--------------------
TO:SqlConnection conn=new SqlConnection( "server=.;database=;uid=sa;pwd= ");

你的数据库名称是故意没写,还是忘了写了??


------解决方案--------------------
if(ConnectMain.State != ConnectionState.Closed)
{
ConnectMain.Close();
}
ConnectMain.Open() ;

打开连接前执行以上代码看看
