// You can also configure the Play Right in the PlayReady license by using the PlayReadyPlayRight class.
// It grants the user the ability to playback the content subject to the zero or more restrictions

// Much of the policy on the PlayRight has to do with output restrictions
// which control the types of outputs that the content can be played over and
// any restrictions that must be put in place when using a given output.
// For example, if the DigitalVideoOnlyContentRestriction is enabled,
//then the DRM runtime will only allow the video to be displayed over digital outputs
//(analog video outputs won’t be allowed to pass the content).
// IMPORTANT: These types of restrictions can be very powerful
// but can also affect the consumer experience.
// If the output protections are configured too restrictive,
// the content might be unplayable on some clients.
// For more information, see the PlayReady Compliance Rules document.
// For example:
//licenseTemplate.PlayRight.AgcAndColorStripeRestriction = new AgcAndColorStripeRestriction(1);

所以我遇到的问题是当我尝试运行程序时，我在这一行得到错误
sbasedrmTableAdapter.Insert(drm_key_id);
我收到的错误是：
错误CS7036没有给出对应的参数 所需的正式参数＆＃39; drm_key＆＃39;的 ＆＃39; sbase_drm_keysTableAdapter.Insert（string，string，string，string）＆＃39;
我该如何解决这个错误
答案 0 :(得分：1)
看起来你试图调用一个只需要一个参数就需要4个字符串作为参数的方法。尝试为方法提供正确的参数。
非常相似
