为什么到SQL Server的c＃连接字符串不能与Windows身份验证一起使用？

Question

Why won't my connection string to SQL server work with Windows authentication? A sql user works fine, acme\\administrator or administrator@acme.com won't work. This is a Win Form app written in C#.

    {
        OdbcConnection cn = null;
        String connectionString;
            connectionString = "Driver={SQL Server};Server=" + cbxDataSources.Text +";Database=" + strDatabase + ";";

            connectionString += "UID=" + textBoxUserName.Text + ";";
            connectionString += "PWD=" + textBoxPassword.Text + ";";

        cn = new OdbcConnection(connectionString);
        return cn;
    }

Thanks guys

Answer 1

You are using SQL Server authentication.

Windows authentication authenticates your connection with the Windows identity of the currently executing process or thread. You cannot set a username and password with Windows authentication. Instead, you set Integrated Security = SSPI.

Answer 2

You have to connect using a Trusted Connection.

2005:

Driver={SQL Native Client};Server=myServerAddress;Database=myDataBase;Trusted_Connection=yes;

2000:

Driver={SQL Server};Server=myServerAddress;Database=myDataBase;Trusted_Connection=Yes;
