我的界面有两个相同名称的实现,如下所示:

interface IDBCaller
{ 
    IEnumerable<User> RetrieveUserList();

{

    public IEnumerable<User> RetrieveUserList()
    {
        return new List<User>();
    }

    public void Method1()
    {
        //doing something
    }

    public void Method2()
    {
        //doing something
    }
}
//Second implementation of IDBCaller in project2 
class DBCaller: IDBCaller
{

    public IEnumerable<User> RetrieveUserList()
    {
        return null; //Currently returns null but the desire state is to call the RetrieveUserList in Implementation1 from project 1
    }
    public …
