我有这个 app.config :
<?xml version="1.0"?>
<configuration>
<configSections>
<sectionGroup name="userSettings" type="System.Configuration.UserSettingsGroup, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" >
<section name="Alvaro1.Properties.Settings" type="System.Configuration.ClientSettingsSection, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" allowExeDefinition="MachineToLocalUser" requirePermission="false" />
</sectionGroup>
</configSections>
<connectionStrings>
<add name="conexx" connectionString="Data Source=192.168.1.2 ;Initial Catalog =ifdcontroladoria3 ;uid =sa;pwd = admin2012" providerName="System.Data.SqlClient" />
</connectionStrings>
<startup><supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0,Profile=Client"/></startup>
<userSettings>
<Alvaro1.Properties.Settings>
<setting name="servidor" serializeAs="String">
<value />
</setting>
<setting name="banco" serializeAs="String">
<value />
</setting>
<setting name="user" serializeAs="String">
<value />
</setting>
<setting name="senha" serializeAs="String">
<value />
</setting>
</Alvaro1.Properties.Settings>
</userSettings>
我在标题和参考中设置了 system.configuration,并使用此代码保存值:
Properties.Settings.Default.servidor = comboBox1.Text;
Properties.Settings.Default.banco = cmbBancos.Text;
但是当我尝试读取这些值时,什么都没有保存:
servidor = Properties.Settings.Default.servidor;
banco = Properties.Settings.Default.banco;
lblLevanta.Text = servidor + " " + banco;
我做错了什么
