Question

我知道其他用户之前已经发布了此消息，我已经尝试查看已经回答的所有答案并尝试了一切，但似乎没有任何工作。所以我在这里用我的代码再次发布问题....请帮助我...这在本地机器上工作正常并且生成水晶报告但是当我把它放在服务器上时它要求提供更多信息数据库，如服务器名称，用户名，密码...尝试了一切但没有用....请帮助......

我遇到了同样的问题，这段代码应该可行

TableLogOnInfos crtableLogoninfos = new TableLogOnInfos()
TableLogOnInfo crtableLogoninfo = new TableLogOnInfo();
var connectionInfo = new ConnectionInfo();
connectionInfo.ServerName = "157.182.x.xxx";
connectionInfo.DatabaseName = "xxxx";
connectionInfo.Password = "xxxx";
connectionInfo.UserID = "xxxx";
connectionInfo.Type = ConnectionInfoType.SQL;
for (int i = 0; i < CrystalReportViewer1.LogOnInfo.Count; i++)
  {
      CrystalReportViewer1.LogOnInfo[i].ConnectionInfo = connectionInfo;
  }

从本地计算机移动到服务器时，Crystal需要更多信息才能登录到数据库
