示例:

protected void btnEncrypt_Click(object sender, EventArgs e)

}
變化:
加密前:
<connectionStrings>
<add name="connStr" connectionString="Data Source=server;Initial Catalog=Lib;User ID=sa;password=3power"
providerName="System.Data.SqlClient" />
</connectionStrings>
加密後:
<connectionStrings configProtectionProvider="DataProtectionConfigurationProvider">

注意:
加密後,仍然可以按以前的操作來讀取,不需要額外的解決操作,因爲
<connectionStrings configProtectionProvider="DataProtectionConfigurationProvider">
這裏已經指定了用何種方式解密,asp.net會自動處理
