C＃SQL Server身份验证字符串

Question

The IT changed the SQL Server to a new Microsoft SQL Server 2017, and some apps stopped working. These apps (C#) use a connection string like this:

SqlConnection conn = new SqlConnection("Data Source=192.168.100.101;Initial Catalog=Warehouse;Persist Security Info=True;User ID=****;Password=******");

But the new server works with Windows authentication. I'd like to know how to change the authentication for the new SQL Server to make apps work again.

Thanks guys.

Answer 1

In that case you can use the Integrated Security options, so the windows account that is running your C# program will be used

SqlConnection conn = new SqlConnection("Data Source=192.168.100.101;Initial Catalog=Warehouse;Integrated Security=True");
