+AnyCPU仅为C# DLL，C# SDK还依赖于C++实现的SDK，所以需要根据运行的目标平台选择对应版本的“MOZA_API_C.dll”和“MOZA_SDK.dll”。
+
+AnyCPU applies only to the C# DLL.
+Since the C# SDK also depends on the SDK implemented in C++, you need to select the corresponding versions of MOZA_API_C.dll and MOZA_SDK.dll according to the target platform you are running on.

+ *
+ * For other APIs in MOZA SDK, please refer to the example code file `sdk_api_test.cc` in the MOZA SDK C++ version.
+ * You can also refer to the API documentation of the C++ version, located at `docsEng/index.html`.
+ * The API in the MOZA SDK C# version is almost identical to the C++ version in terms of function names and input parameters.
