根据多个用户条件启用按钮

Question

我有一个名为DisabledControl的用户控件。我需要使用这两个条件创建1 if语句。

public static class DisabledControl
{
    public static void AdminOnly(this Control control)
    {
        control.Enabled = User.IsInRole(new string[] { "Administrator" });
    }

    public static void OwnerOnly(this Control control, int ownerID)
    {
        control.Enabled = (User.ID == ownerID);
    }
}

//I need help with syntax: if User isinRole 'Adminstrator" && user is OwnerOnly, btnSave.Enabled=true. 
//I tried to use if user.id == OwnerOnly, it gives error.

Answer 1

您无法user.id == OwnerOnly，因为OwnerOnly是一种返回void的方法。您需要user.id == ownerID，或更改OwnerOnly才能返回boolean。

回应您的评论，请尝试以下方式：

public static void SetEnabledForAdminOrOwner(this Control control, int ownerID)
{
    control.Enabled = User.IsInRole(new string[] { "Administrator" }) || User.ID == ownerID;
}
