以编程方式通过Crystal Web Services在Crystal Server上设置Crystal Report的数据源

Question

如何更改Crystal报表在运行时在水晶服务器中运行的数据源(数据库服务器,用户名,密码)？

我有一个水晶服务器并上传了具有set数据源的报告(SQL Server 2005托管在SERVER A,userA,passwordA).我想安排报告使用我编写的c#客户端使用不同的数据源(在SERVER B上托管的SQL Server 2005,userB,passwordB)运行.

c#客户端可以使用crystal webservices提供的对象来安排报表在服务器内运行.我一直在使用以下3个对象:

BIPlatform
InfoObject
CrystalReport

有关这些对象的文档可以在这里找到

1/30/2018-只想补充一点,你需要CrystalDecisions.ReportAppServer.DataDefModel dll

我有同样的问题,我有一个有MSAccess数据库连接的报告,我需要将其更改为SQLServer,花了2天时间来解决这个问题:

            reportDocument = new ReportDocument();
            reportDocument.Load(reportFileName);
            TableLogOnInfo tableLogOnInfo = ReportClass.GetSQLTableLogOnInfo(connectionProperties.DatabaseSource, connectionProperties.DatabaseName, connectionProperties.UserName, connectionProperties.Password);
            for (int i = 0; i < reportDocument.Database.Tables.Count; i++)
            {
                Table table = reportDocument.Database.Tables[i];
                table.ApplyLogOnInfo(tableLogOnInfo);
            }

     public static ConnectionInfo GetConnectionInfo(string serverName, string         databaseName, string userID, string password)
    {
        ConnectionInfo connectionInfo = new ConnectionInfo();
        connectionInfo.ServerName = serverName;
        connectionInfo.DatabaseName = databaseName;
        connectionInfo.UserID = userID;
        connectionInfo.Password = password;
        return connectionInfo;
    }

    public static TableLogOnInfo GetSQLTableLogOnInfo(string serverName, string databaseName, string userID, string password)
    {
        CrystalDecisions.ReportAppServer.DataDefModel.PropertyBag connectionAttributes = new CrystalDecisions.ReportAppServer.DataDefModel.PropertyBag();
        connectionAttributes.EnsureCapacity(11);
        connectionAttributes.Add("Connect Timeout", "15");
        connectionAttributes.Add("Data Source", serverName);
        connectionAttributes.Add("General Timeout", "0");
        connectionAttributes.Add("Initial Catalog", databaseName);
        connectionAttributes.Add("Integrated Security", false);
        connectionAttributes.Add("Locale Identifier", "1033");
        connectionAttributes.Add("OLE DB Services", "-5");
        connectionAttributes.Add("Provider", "SQLOLEDB");
        connectionAttributes.Add("Tag with column collation when possible", "0");
        connectionAttributes.Add("Use DSN Default Properties", false);
        connectionAttributes.Add("Use Encryption for Data", "0");

        DbConnectionAttributes attributes = new DbConnectionAttributes();
        attributes.Collection.Add(new NameValuePair2("Database DLL", "crdb_ado.dll"));
        attributes.Collection.Add(new NameValuePair2("QE_DatabaseName", databaseName));
        attributes.Collection.Add(new NameValuePair2("QE_DatabaseType", "OLE DB (ADO)"));
        attributes.Collection.Add(new NameValuePair2("QE_LogonProperties", connectionAttributes));
        attributes.Collection.Add(new NameValuePair2("QE_ServerDescription", serverName));
        attributes.Collection.Add(new NameValuePair2("SSO Enabled", false));

        ConnectionInfo connectionInfo = ReportClass.GetConnectionInfo(serverName, databaseName, userID, password);
        connectionInfo.Attributes = attributes;
        connectionInfo.Type = ConnectionInfoType.SQL;

        TableLogOnInfo tableLogOnInfo = new TableLogOnInfo();
        tableLogOnInfo.ConnectionInfo = connectionInfo;
        return tableLogOnInfo;
    }

您应该尝试获取有关ConnectionInfo 类的一些信息

CrystalDecisions.Shared.ConnectionInfo myConnectionInfo = 
                 new CrystalDecisions.Shared.ConnectionInfo();

myConnectionInfo.DatabaseName = "Database";
myConnectionInfo.UserID = "Username";
myConnectionInfo.Password = "P@ssword";

以编程方式更改 Crystal Reports 数据源位置- 在 VB 中，但您可以使用在线翻译工具之一从 VB 转换为 C#：
