```cpp
virtual void Shutdown() = 0;
```

关闭并释放采样器资源。该方法用于在采样器不再需要时进行清理工作，释放底层图形 API 分配的资源。

**参数：** 无

**返回：** 无

**线程安全：** ❌

**复杂度：** O(1)

**示例：**

```cpp
#include "XCEngine/RHI/RHISampler.h"

class MySampler : public XCEngine::RHI::RHISampler {
public:
    void Shutdown() override {
        if (m_initialized) {
            ReleaseNativeResource();
            m_initialized = false;
        }
    }
    void Bind(unsigned int unit) override { }
    void Unbind(unsigned int unit) override { }
    void* GetNativeHandle() override { return nullptr; }
    unsigned int GetID() override { return 0; }

private:
    bool m_initialized = true;
    void ReleaseNativeResource() { }
};

void Example() {
    MySampler sampler;
    sampler.Shutdown();
}
```
