我做错了什么（SQLServerCE中的Getschema方法）？

本文介绍了我做错了什么（SQLServerCE中的Getschema方法）？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 我对SQLServerCe命名空间中的Getschema方法有疑问 - 我在C＃中相当新，所以我可能忽略了一些东西。 I have a problem with the Getschema method in the SQLServerCe namespace - I am fairly new in C# so I may have overlooked something. 我的问题是我只有C＃Express版本（我没有移动项目）所以我被"强迫"了为我的SQL Compact数据库（.sdf）创建自己的查看器，因为我无法使用SQL Server Management Studio Express来存储这些文件。但是，当我在相应的命名空间中使用Getschema（）方法时，它似乎不起作用。My problem is that I have only the C# Express edition (I don't have the mobile projects) so I am "forced" to make my own viewer for my  SQL Compact databases (.sdf) as I can't use SQL server Management Studio Express for these files. However, when I use the Getschema() method in the corresponding namespace it seems to not work.这是我使用的代码： string connstring = @"数据源= c：\！studiec＃\betatest.sdf" ; string connstring = @"Data Source=c:\!studiec#\betatest.sdf"; SqlCeConnection myconn = new SqlCeConnection （@ connstring）; SqlCeConnection myconn = new SqlCeConnection(@connstring); myconn.Open（）; myconn.Open(); DataTable mytable = myconn.GetSchema （）; DataTable mytable = myconn.GetSchema(); 我收到错误"不支持指定方法" - 但我找不到错误。根据MSDN数据库，SQLServerCE命名空间支持（重载）的Getschema方法，智能感知也会感知它。尝试以下语法给了我相同的错误消息：I get the error   "Specified method is not supported" -but I can't find the errors. According to the MSDN database the (overloaded) Getschema method is supported within the SQLServerCE namespace , also intellisense senses it. Trying the following syntax  gave the me same error message: string connstring = @" Data Source = c：\！studiec＃\betatest.sdf" ; string  connstring = @"Data Source=c:\!studiec#\betatest.sdf"; SqlCeConnection myconn = new SqlCeConnection （@ connstring）; SqlCeConnection myconn = new SqlCeConnection(@connstring); myconn.Open（）; myconn.Open(); DataTable mytable = myconn.GetSchema（" Tables"）; DataTable mytable = myconn.GetSchema("Tables"); 有人可以帮助我并指出我做错的地方吗？提前致谢。Someone can help me and point me where I did wrong? Thanks in advance. Bipolar Penguin Bipolar Penguin 推荐答案 确保你使用.net framework 2.0和C＃express 2005.GetSchema wasn' t支持1.1 Make sure you're using .net framework 2.0 and C# express 2005. GetSchema wasn't supported in 1.1 这篇关于我做错了什么（SQLServerCE中的Getschema方法）？的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
