我可以将它存储在app.config中吗？ [英] Can I store this in app.config?
问题描述
我想存储以下内容我的app.config
文件：
<？xml version =" 1.0"编码= QUOT; UTF-8英寸？>
< configuration>
< appSettings>
< add key =" DEBUG" value =" true" />
< add key =" DEBUGCleanFile" value =" true" />
< / appSettings>
< DataGridColumnCollection>
< AGrid value =" true">
< / AGrid>
< BGrid value =" false">
< column1 value =" true" />
< column2 value =" true" />
< column3 value =" true" />
< / Bgrid>
< / DataGridColumnCollection>
< system.diagnostics>
< /system.diagnostics>
< / configuration>
我特别想要DataGridColumnCollection部分。我可以使用XMLDocument对象从文件中读取
数据。然而，
奇怪的事情发生了。例如，在这一行：
使用（SqlConnection连接=新的SqlConnection（connectionString））
我得到这个例外：
''System.Data.SqlClient.SqlConnection'的类型初始化程序抛出了
异常。
该应用程序.config和以上行完全不相关。当我删除DataGridColumnCollection的
时，一切都很好，但当然我放松了所有这些数据。现在，我正在使用我自己的XML文件，但这只是更多的文件。关于如何将
DataGridColumnCollection部分粘贴到app.config中的任何建议？
谢谢，
Brett
I''d like to store something such as the following the my app.config
file:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<appSettings>
<add key="DEBUG" value="true"/>
<add key="DEBUGCleanFile" value="true"/>
</appSettings>
<DataGridColumnCollection>
<AGrid value="true">
</AGrid>
<BGrid value="false">
<column1 value="true"/>
<column2 value="true"/>
<column3 value="true"/>
</Bgrid>
</DataGridColumnCollection>
<system.diagnostics>
</system.diagnostics>
</configuration>
I particularly want the DataGridColumnCollection section. I can read
the data fine out of the file using an XMLDocument object. However,
weird things happens. For example, on this line:
using(SqlConnection connection = new SqlConnection(connectionString))
I get this exception:
The type initializer for ''System.Data.SqlClient.SqlConnection'' threw an
exception.
The app.config and above line are completely unrelated. When I remove
the DataGridColumnCollection, everything is fine but of course I loose
all of that data. For now, I''m using my own XML file but that is just
more files to haul around. Any suggestions on how I can stick the
DataGridColumnCollection section into app.config?
Thanks,
Brett
推荐答案
Hello Brett，
DataGridColumnCollection是一个类，据我所知？
然后序列化并保持编码就像一个字符串
BRI'想要存储以下内容我的app.config
BRfile：
BR>
BR<？xml version =" 1.0"编码= QUOT; UTF-8英寸？>
BR< configuration>
BR< appSettings>
BR< add key =" DEBUG" value =" true" />
BR< add key =" DEBUGCleanFile" value =" true" />
BR< / appSettings>
BR< DataGridColumnCollection>
BR< AGrid value =" true" ;>
BR< / AGrid>
BR< BGrid value =" false">
BR< column1 value =" true" />
BR< column2 value =" true" />
BR< column3 value =" true" />
BR< / Bgrid>
BR< / DataGridColumnCollection>
BR< system.diagnostics>
BR< /system.diagnostics>
BR< / configuration>
BRI尤其需要DataGridColumnCollection部分。我可以
使用XMLDocument对象将数据清理干净。
BR但是，奇怪的事情发生了。例如，在这一行：
BR>
BRusing（SqlConnection connection = new
BRSqlConnection（connectionString））
BR>
BRI得到此例外：
BR>
BR''System.Data.SqlClient.SqlConnection''的类型初始值设定项扔了
BRan例外。
BR>
BR app.config及以上行完全不相关。当我支持
BRremove DataGridColumnCollection时，一切都很好但是
BRcourse我放弃了所有这些数据。现在，我正在使用我自己的XML文件
BRbut这只是更多的文件。关于
BRI如何将DataGridColumnCollection部分粘贴到app.config中的任何建议？

BRThanks，

Hello Brett,
DataGridColumnCollection is a class, as I understand?
Then serialize it and keep it encoded just like a string
BRI''d like to store something such as the following the my app.config
BRfile:
BR>
BR<?xml version="1.0" encoding="utf-8" ?>
BR<configuration>
BR<appSettings>
BR<add key="DEBUG" value="true"/>
BR<add key="DEBUGCleanFile" value="true"/>
BR</appSettings>
BR<DataGridColumnCollection>
BR<AGrid value="true">
BR</AGrid>
BR<BGrid value="false">
BR<column1 value="true"/>
BR<column2 value="true"/>
BR<column3 value="true"/>
BR</Bgrid>
BR</DataGridColumnCollection>
BR<system.diagnostics>
BR</system.diagnostics>
BR</configuration>

我没有使用那个班级。我们称之为MyDataGridColumnCollection。我
仍然得到sqlclient异常。
谢谢，
Brett
I''m not using that class. Let''s call it MyDataGridColumnCollection. I
still get the sqlclient exception.
Thanks,

Brett，
如果要在配置文件中存储自定义XML元素/节点，
它们必须是可识别元素或简单键= x value = y元素
appSettings部分。
否则，你需要在
配置中声明一个自定义配置部分并拥有一个自定义的sectionhandler来读取它。迈克尔关于
序列化课程的评论是正确的。
显然，需要进行一些研究，但如果这是你想要的方式
存储您的自定义数据，值得。

Brett,
If you want to store custom XML elements/ nodes in a configuration file,
they must either be recognized elements, or simple key=x value=y elements in
the appSettings section.
Otherwise, you need to declare a custom configuration section in your
config and have a custom sectionhandler to read it. Michael''s comments about
serializing a class are correct.
Obviously, some study will be required but if this is the way you want to
store your custom data, it will be worth it.
