Answer 1

试试这个

<add name="database" connectionString="Data Source=172.20.145.67;Initial Catalog=Database1;User ID=sa;Password=321"/>

删除单引号

Answer 2

您不需要在连接字符串中引用字符串。

<add name="database" connectionString="Data Source=172.20.145.67;Initial Catalog=Database1;User ID=sa;Password=321"/>

无法打开登录'Database1'中请求的数据库。登录失败。用户'sa'登录失败
