c# - 基于多个用户条件启用的按钮

Question

我有一个名为 DisabledControl 的用户控件。我需要用这两个条件创建 1 个 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

您不能执行 user.id == OwnerOnly，因为 OwnerOnly 是一种返回 void 的方法。您将需要 user.id == ownerID，或更改 OwnerOnly 以返回一个 boolean。

为了回应您的评论，尝试这样的事情:

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