well i am working for PocketPc and it has a library (System.data) and (System.data.sqlclient) then THEY are not complete libraries then i need use System.data (the complete library) but now i have 2 dll s calls (System.data) and the complete library has System.data.sqlclient too, then i have problem with them, so if i only use the complete library i have another problem, cuz the System.data( no complete library) has one thing wich System.data(Complete library) doesn t have, so i need use 2 dlls (with same namespace) and i have problems...

Answer 1

见 inMSDN and a tutorial在视觉演播室使用。

从指挥系统编中,参考资料被宣布为:

/r:SystDataOfficial=System.Data.dll
/r:SystDataOther=data.dll

之后,在您的法典中:

extern alias SystDataOfficial;
extern alias SystDataOther;

var c = new SystDataOfficial::System.Data.SqlClient();

你们还可以把lls作为 alia子之一,通常使用另一 the。

请注意,这些赢得的类型可以一起使用。这部法律赢得了以下工作:

// Expect SystDataOfficial::SomeConstant
SystDataOfficial::System.Data.SqlClient.SomeMethod(SystDataOther::SomeConstant);

Answer 2

是,见

但是,它们仍然是不同类型的,而你却通过自己制造的物体去做其他方法。
