如何从dll文件而不是从webconfig设置asp.net标识连接字符串

Question

I m working for a company that they use dll for connection string and i m正在尝试更改ApplicationDbContext类中的asp.net标识默认连接字符串，我使用dll的连接类是这样的：

public class HRConnection
{       
    public string HR_con
    {
        get
        {
            return "server=192.168.1.21; database=HR; user=teamuser ; password=t123@456  ; connection timeout=30";                
        }
    }
}

i ve tried to pass string like this , but it didn t工作

public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{
    string  HrConn = new HRConnection().HR_con;
    public ApplicationDbContext()
        : base(HrConn, throwIfV1Schema: false)
    {
    }
}

如何在代码中而不是在webconfig文件中设置连接？

Answer 1

我像这个一样解决了我的问题

public ApplicationDbContext()
        : base(new HRConnection().HR_con, throwIfV1Schema: false)
    {
    }

Answer 2

首先尝试将硬编码字符串作为调用中的第一个参数传递给base。如果这有效，那么我建议这样定义你的字符串：

public class HRConnection
{       
    public readonly static string HR_con = "server=192.168.1.21; database=HR; user=teamuser ; password=t123@456  ; connection timeout=30";
}

并像这样使用：

public ApplicationDbContext()
        : base(HRConnection.HR_con, throwIfV1Schema: false)
    {
    }
