读取app.config文件中的自定义内容

在configuration节点添加:

<userSettings>
        <WpfSmartClientStarter.Properties.Settings>

            <setting name="FTPPassword" serializeAs="String">
                <value>dm189</value>
            </setting>
    </WpfSmartClientStarter.Properties.Settings> 
    </userSettings>

在cs文件中读取:

 string FTPPassword = WpfSmartClientStarter.Properties.Settings.Default["FTPPassword"].ToString();
