Crystal Reports使用VS 2010连接到多台服务器 [英] Crystal Reports connect to several servers using VS 2010

问题描述

检查此情况

多个SQL Server包含相同的数据库(不必具有相同的名称，但当然也具有相同的结构)

希望有一个Winform应用程序(使用VS2010

C#

创建)能够从上述数据库中生成报告(使用Crystal Reports).

每次启动该应用程序时，都应询问用户哪个服务器使用，数据库名称，用户名和密码.基于此信息，将执行报告.

问题:如何将这些参数传递到解决方案中的.rpt文件中，以完成上述任务?我的意思是，以编程方式使用C#

谢谢.

Check this scenario

Several SQL-Servers contains the same DB(not necessary with the same name but of course the same structure)

It is desirable to have a winform application(created using VS2010

C#

) capable to make reports (using Crystal Reports) from the DB mentioned above.

Every time the app is launched should ask to the user which Server Use, name of DB, username and password. Based on this information, the report is executed.

Question: How those parameter are passed to the .rpt files inside the solution in order to accomplish the mentioned above? I mean, programatically using C#

Thank you.
