| nameSpace | The ContentNamespace used to filter the results. |
| filename | 文件在磁盘上的路径。 |
| dependencies | List of the ContentFiles that will be referenced by the file being loaded. The ordering must match the ordering returned from the build process. ContentFile.GlobalTableDependency can be used to indicate that the PersistentManager should be used to resolve references. This allows references to files such as "unity default resources". |
| dependentFence | The load will not begin until this JobHandle completes. A default JobHandle can be used if there is no dependency. |
ContentFile Handle to access the results of the load process.
Loads a serialized file asynchronously from disk.
The status of the load operation can be accessed using the returned ContentFile. Objects loaded with this function will not be garbage collected; the user is responsible for calling ContentFile.UnloadAsync to free resources when they are no longer required. The user must call ContentFile.UnloadAsync even if the load fails.
