 # Thread::GetCurrentId
 
 ```cpp
-static Id GetCurrentId()
+static Id GetCurrentId();
 ```
 
-获取当前执行线程的唯一标识符。这是一个静态方法，可以在任何线程上下文中调用。
+静态方法，返回当前执行线程的唯一标识符。此方法可在任意线程上下文中调用，包括主线程和工作线程。
+
+线程 ID 通过 `std::this_thread::get_id()` 获取，并使用 `std::hash<std::thread::id>` 转换为 `uint64_t` 值。该值与 `Thread::GetId()` 返回的值格式一致，可以直接比较。
 
 **参数：** 无
 
-**返回：** `Thread::Id` - 当前执行线程的唯一标识符
+**返回：** 调用线程的唯一标识符
 
-**复杂度：** O(1)
+**线程安全：** ✅
 
 **示例：**
 
 ```cpp
-Thread worker;
-worker.Start([]() {
-    printf("Worker thread id: %llu\n", (unsigned long long)Thread::GetCurrentId());
-}, "WorkerThread");
+#include "XCEngine/Threading/Thread.h"
+#include <iostream>
 
-printf("Main thread id: %llu\n", (unsigned long long)Thread::GetCurrentId());
-worker.Join();
+using namespace XCEngine::Threading;
+
+int main() {
+    std::cout << "Main thread ID: " << Thread::GetCurrentId() << std::endl;
+    
+    Thread t;
+    t.Start([]() {
+        std::cout << "Worker thread ID: " << Thread::GetCurrentId() << std::endl;
+        std::cout << "Worker ID matches Thread.GetId(): " 
+                  << (Thread::GetCurrentId() == t.GetId() ? "Yes" : "No") << std::endl;
