WPF 客户端应用程序连接到服务器中的数据库。客户端电脑没有安装 MS sql 服务器。所以我在客户端 PC 中安装了 sql server native client 最新版本。但是当我尝试查看报告时，我收到以下错误消息。我仔细检查了 app.config 中的数据库连接字符串，它包含正确的登录信息。

<message>Logon failed.Error in File EmployeeMealSummary {B32AECDC-7F60-4BD9-B2C9-F8153BF2CB5A}.rpt: Unable to connect: incorrect log on parameters.</message>   
<source>rptcontrollers.dll</source>
<stackTrace>at CrystalDecisions.ReportAppServer.Controllers.DatabaseControllerClass.SetTableLocation(ISCRTable CurTable, ISCRTable NewTable)

在 CrystalDecisions.CrystalReports.Engine.Table.set_Location（字符串值）

我附上了代码。请帮我解决这个问题。

private void SetDBLogonForReport(ConnectionInfo connectionInfo, ReportDocument     reportDocument)
{
    CrystalDecisions.Shared.TableLogOnInfo crTableLogonInfo;
    CrystalDecisions.CrystalReports.Engine.Tables crTables = _report.Database.Tables;

    foreach (CrystalDecisions.CrystalReports.Engine.Table crTable in crTables)
    {
        crTableLogonInfo = crTable.LogOnInfo;
        crTableLogonInfo.ConnectionInfo.LogonProperties.Clear();
        crTableLogonInfo.ConnectionInfo.Attributes.Collection.Clear();
        crTableLogonInfo.ConnectionInfo.DatabaseName = null;
        crTableLogonInfo.ConnectionInfo.ServerName = connectionInfo.ServerName;
        crTableLogonInfo.ConnectionInfo.UserID = connectionInfo.UserID;
        crTableLogonInfo.ConnectionInfo.Password = connectionInfo.Password;
        crTableLogonInfo.ConnectionInfo.DatabaseName = connectionInfo.DatabaseName;
        crTable.ApplyLogOnInfo(crTableLogonInfo);

        if (crTable.Name == "vEmployee" || crTable.Name == "TB_USER_DEPT" )
        {
            CenUtility.ErrorLog.CreateLog(new ArrayTypeMismatchException());
            crTable.Location = connectionInfo.DatabaseName + ".dbo." + crTable.Location; 
        }
        else
        {
            crTable.Location = connectionInfo.DatabaseName + ".CafDB." + crTable.Location;
        }
    }
}

我遇到了同样的问题，我设置了数据库的位置并更新了表格检查您是否通过了正确的方法（数据库名称、密码、用户 ID、服务器名称）尝试这种方式并告诉我它是否以正确的方式工作
