How to select the data by unicode where condition?

问题

I would like to get the data base on following SQL Statement and that was located in TableAdapter.

SELECT * FROM Student WHERE Chinese_Name = @Param

Example code call from C# is like this.

GetDataByChinese_Name('你好');

But I have no idea where should I put the N prefix in that syntax. Usually, we can get

SELECT * FROM Student WHERE Chinese_Name = N'你好'

this way.

回答1:

Your c# code should be slightly different. Use verbatim string literal.(msdn)

    GetDataByChinese_Name(@"你好");
