大家好，我已经创建了一个小型Windows应用程序，并从Windows Mobile应用程序连接了sql server2005.
建立连接时，我不支持该平台.

System.PlatformNotSupportedException was unhandled

这是我的代码在这里

and this is my code here

SqlConnection conn = null;
 string conString;

conString ="Data Source=192.168.100.11;Initial Catalog=PDA;Integrated Security=SSPI;User ID=mydomain\\usewrid;Password=mypassword";

conn = new SqlConnection(conString);
conn.Open();

我在conn.open()的这一行中遇到错误；


如何解决此错误.

i am getting error in this line of conn.open();


how to fix this error.

推荐答案

正在使用的WinCE/Windows Mobile设备不支持数据库的排序规则，即它缺少代码页从构建.您应该能够通过将排序规则更改为服务器端的其他排序规则(例如SQL Latin或类似名称)来进行测试.

我看到了与WinCE 6.0设备相同的情况，其中成功连接到具有"Latin1_General_CI_AI"排序规则的数据库，但连接至具有"Romanian_CI_AS"的数据库失败.通过获取WinCE映像的更新最终解决了该问题，其中添加了所需的代码页1520.另一种选择是将数据库排序规则更改为手持设备支持的内容.

The collation of your database is not supported on the WinCE/Windows Mobile device you are using, i.e. it''s missing the codepage from the build. You should be able to test it by changing to collation to something else on server side, for example SQL Latin or similar.

I saw the same situation with a WinCE 6.0 device where connecting to a DB with "Latin1_General_CI_AI"-collation succeeded but connecting to a DB with "Romanian_CI_AS" failed. The problem was eventually solved by acquiring an update for the WinCE image where the required codepage 1520 was added. Another option is just to change the database collation to something that is supported on your handheld device.

可能是因为您尝试连接到错误的平台，必须连接到
SqlCE [ ^ ].用于紧凑型框架.

May be you are trying to connect to the wrong flatform, you have to connect to the
SqlCE[^]. for Compact Framwork.
