问题描述
我通常使用一个文本文件作为一个配置。但是这一次,我想利用的app.config到一个文件名(键)与名称(值)相关联,并在组合框中的名称
I usually use a text file as a config. But this time I would like to utilize app.config to associate a file name (key) with a name (value) and make the names available in combo box
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<appSettings>
<add key="Scenario1.doc" value="Hybrid1"/>
<add key="Scenario2.doc" value="Hybrid2"/>
<add key="Scenario3.doc" value="Hybrid3"/>
</appSettings>
</configuration>
将这项工作?如何找回数据?
will this work? how to retrieve the data ?
推荐答案
直接从的:
// Get the AppSettings section.
// This function uses the AppSettings property
// to read the appSettings configuration
// section.
public static void ReadAppSettings()
{
try
{
// Get the AppSettings section.
NameValueCollection appSettings =
ConfigurationManager.AppSettings;
// Get the AppSettings section elements.
Console.WriteLine();
Console.WriteLine("Using AppSettings property.");
Console.WriteLine("Application settings:");
if (appSettings.Count == 0)
{
Console.WriteLine("[ReadAppSettings: {0}]",
"AppSettings is empty Use GetSection command first.");
}
for (int i = 0; i < appSettings.Count; i++)
{
Console.WriteLine("#{0} Key: {1} Value: {2}",
i, appSettings.GetKey(i), appSettings[i]);
}
}
catch (ConfigurationErrorsException e)
{
Console.WriteLine("[ReadAppSettings: {0}]",
e.ToString());
}
}
所以,如果你要访问的设置 Scenario1.doc
,你可以这样做:
VAR值= ConfigurationManager.AppSettings [Scenario1 .DOC];
编辑:
加布里埃尔通用在说评论,你将不得不增加 System.Configuration
引用。
As Gabriel GM said in the comments, you will have to add a reference to System.Configuration
.
