从App.Config中读取设置

Question

配置文件.

我应该如何使用System.Configuration.ConfigurationManager类在C#中读取用户名和密码的值？我尝试过几种东西,但无济于事.

app.config如下所示.

<configuration>
    <configSections>
        <sectionGroup name="applicationSettings" type="System.Configuration.ApplicationSettingsGroup, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" >
            <section name="Fulfillment.Properties.Settings" type="System.Configuration.ClientSettingsSection, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
        </sectionGroup>
    </configSections>
    <applicationSettings>
        <Fulfillment.Properties.Settings>
            <setting name="username" serializeAs="String">
                <value>MyUserName</value>
            </setting>
            <setting name="password" serializeAs="String">
                <value>MyPassword</value>
            </setting>
        </Fulfillment.Properties.Settings>
    </applicationSettings>
</configuration>

请帮忙.谢谢.

如果值位于文件的appSettings部分中:

<appSettings>
  <add key="myUsername" value="david"/>
  <add key="myPassword" value="iLikeHalibut"/>
</appSettings>

您可以按如下方式阅读:

string myUsername = System.Configuration.ConfigurationManager.AppSettings["myUsername"];

您需要确保您编程的程序集包含对System.Configuration.dll的引用(默认情况下并不总是存在).
