[解决办法]
没人来答你啊。呵呵。连接写错了。没有。
[解决办法]
string strCon = "Data Source=.;Database=diary.xml;Uid=sa;Pwd=";
UserID = sa ; Pwd = ? 没有密码的？
[解决办法]
用户名对么？连接的格式好像不对
[解决办法]
用户名对么？连接的格式好像不对
[解决办法]
server=.;database=数据库名;uid=sa;pwd=sa
你的没写密码啊...
[解决办法]
string strCon = "Data Source=.;Database=diary.xml;Uid=sa;Pwd=";
密码？
