我创建了包含 3 个项目的解决方案。

//Project Name: ClientProject
    public class UserDetails
    {
        public static int ID { get; set; }
        public static string Name { get; set; }
        public static string Email { get; set; }
    }

上面的这个类应该设置一次，当用户登录之后，我想在整个解决方案中访问这些详细信息。

像管理，SalesInfo 项目。

//Project Name: Administration
    public class Admin
    {
        public static UserDetails Details
        {
            //Here i would like to return UserDetails
            get; 
        }
        public static int DepartmentID { get; set; }
        public static string Phone { get; set; }
        public static string Head { get; set; }
    }

    //Project Name: SalesInfo
    public class Sales
    {
        public static UserDetails Details
        {
            //Here i would like to return UserDetails
            get;
        }
        public static DateTime Date { get; set; }
        public static string Item { get; set; }
        public static int Price { get; set; }
    }

任何答案、评论或建议将不胜感激

Normally property uses private field to store the data. This behavior added during compile time and is hidden for the developer while coding. Static method/property can't access private variables/fields in a class.

I recommend to use singleton pattern.

public class UserDetails
{
    private static UserDetails _instance;

    public int ID { get; set; }
    public string Name { get; set; }
    public string Email { get; set; }

    private UserDetails() {}

    public static UserDetails Instance
    {
        get
        {
            if (_instance == null)
            {
                 _instance = new UserDetails();
            }
            return _instance;
        }
    }
}

And you can consume like this,

//Project Name: Administration
public class Admin
{
    public static UserDetails Details
    {
        get
        {
            return UserDetails.Instance;
        } 
    }
    public static int DepartmentID { get; set; }
    public static string Phone { get; set; }
    public static string Head { get; set; }
}

使用 Groo 提到的一种单例。 

public class UserDetails
{
  public static int ID { get; private set; }
  public static string Name { get; private set; }
  public static string Email { get; private set; }

  private static UserDetails _userDetails;

  private UserDetails(int id, string name, string email)
  {
    ID = id;
    Name = name;
    Email = email;
  }

  public static UserDetails CreateUserDetails(int id, string name, string email)
  {
    if (_userDetails != null)
    {
      throw new MyException("Second call to UserDetails.CreateUserDetails!");
    }
    _userDetails = new UserDetails(id, name, email);

    return _userDetails;
  }

  public static UserDetails GetUserDetails()
  {
    if (_userDetails == null)
    {
      throw new MyException("Not yet created by calling UserDetails.CreateUserDetails!");
    }

    return _userDetails;
  }

}

登录后调用UserDetails.CreateUserDetails(...)设置全局对象。
要获取详细信息，请致电GetUserDetails()。
