I have also created a database table for form1 with username and password, with admin and user as 2 entities and related records too. where form2 contains 2 buttons admin and users. the question is.. when i log in as an admin i want all the buttons in form2 enabled..when logged in as user i only want users button to be enabled and admin to be disabled. please could anyone help me with this coding ..?

推荐答案

正如 TaW 所说，form2 的 flag 参数构造函数应该运行.

As TaW said, the flag parameter in form2's constructor should run.

另一种可能是在form2中创建一个属性:

Another possibility is to create a property in form2:

    private bool isAdmin;

    public bool IsAdmin
    {
        get
        {
            return isAdmin;
        }

        set
        {
            isAdmin = value;
            btnAdmin.Enabled = isAdmin;
        }
    }

并在显示form2之前在form 1中使用它.对于管理员:

and use it in form 1 before you show form2. For an admin:

    var f = new Form2 { IsAdmin = true };
    f.Show();

对于普通用户:

    var f = new Form2 { IsAdmin = false };
    f.Show();

希望有帮助.
