推荐答案

您必须编写代码才能做到这一点.您可以选择将凭据存储在数据库中(如果您的应用程序有一个凭据)，也可以存储在XML文件或文本文件中.

请确保使用强大的加密方案对密码进行加密.

You have to write code to do that. You can choose to store the credentials in the database (if your app has one), or in an XML file or a text file.

Be sure to encrypt the password using a strong encryption scheme.

如果使用Winform应用程序.您可以将用户标识和密码存储在用户的MyDocumentsFolder中的txtfile中. (System.Environment.SpecialFolder.MyDocument)
您可以使用Userid，Password或要从该用户保存的任何其他设置创建一个简单的类，然后将其序列化到该文件.
登录期间，如果该文件存在，则将其反序列化并验证身份验证

If its Winform Applcation . You can store the userid and password in txtfile in MyDocumentsFolder of the user. (System.Environment.SpecialFolder.MyDocument)
You can create a simple class with Userid,Password, or any more settings that you want to save from that user and then can serialize it to that file.
During login if that file exist you deserialize it and verify the authentication
