How can I create a foreign key relationship in Visual Studio when writing out the tables?-CodePudding

I have the 2 tables in the picture below and want to add a foreign key relationship between them with the ServiceID being the foreign key

My 2 tables side by side My Database Context

CodePudding user response：

Add the following to ServiceStatistics:

[ForeignKey("ServiceLogRefId")]
public ServiceLog ServiceLog {get; set; }

public int ServiceLogRefId {get; set; }

May be a slight difference in annotation given version (you haven't specified in your question).

CodePudding user response：

your code can like this:

public class LoginLog
{
    .
    .
    .
    public int ServiceStateId{ get; set; }
    public ServiceState ServiceState{ get; set; }
}
public class ServiceState 
{
    .
    . 
    .
    public ICollection<LoginLog> LoginLogs{ get; set; }
}

also you get all info about relations in this link:Relation in EF
