如何定義公共的報表實例名稱,在線等解救,謝謝!

[mailbao]

現有如下代碼

if (Utility.CurrentUser == "A")
{
crInvoice_1 cr1 = new crInvoice_1();
}

if (Utility.CurrentUser == "B")
{
crInvoice_2 cr1 = new crInvoice_2();
}
......

我如何在這代碼之上,定義公共的變量cr1,方便以下代碼調用cr1??

cr1.SetDataSource(CrCtrl.GetDss(sql1, sql2, returnTableName1, returnTableName2));
this.crvReport.ReportSource = cr1;
......


但如果不定義的話,則對應不同的User就得包括好多代碼(可這些代碼都是一樣的,感覺重複太多...)

[Quote=引用 3 楼 babyt 的回复:]
Object mycr;

if (Utility.CurrentUser == "A")
{
mycr = new crInvoice_1();
}

if (Utility.CurrentUser == "B")
{
mycr = new crInvoice_2();
}


這方法在下面引用時會報錯
mycr.SetDataSource(CrCtrl.GetDataSet(sql, dsName));

報錯如下:

'object' does not contain a definition for 'SetDataSource' and no extension method 'SetDataSource' accepting a first argument of type 'object' could be found

我现在没环境测试，你把

Object xx ;
==>
改成
ReportDocument xx;

看一下是否可行~~

[mailbao]

試過,依然不行,汗~~ 難道真的要重複一大堆同樣的代碼??

呵呵，我前面只测试到能出来setdatasource方法，没有继续测试。

或许你可以看一下这种思路

支持一下，crInvoice_1和crInvoice_2是继承自同一个类吗

[mailbao]

crInvoice_1和crInvoice_2是不同的兩個報表類,
類似歸屬於不同用戶組的報表,但我想將它們在第三方窗體上通過一個公共變量和User所屬的用戶組來調用...

Object mycr;

if (Utility.CurrentUser == "A")
{
mycr = new crInvoice_1();
}

if (Utility.CurrentUser == "B")
{
mycr = new crInvoice_2();
}
