.net 调用虽然wiki中有相关插件，但是缺少大文件上传的实现。

https://github.com/chrislusf/seaweedfs/wiki/Large-File-Handling

seaweedfs上传大文件需要自己将大文件分片上传，然后构建manifest json文件记录分片的文件信息

type ChunkInfo struct {
	Fid    string `json:"fid"`
	Offset int64  `json:"offset"`
	Size   int64  `json:"size"`
}


type ChunkList []*ChunkInfo

type ChunkManifest struct {
	Name   string    `json:"name,omitempty"`
	Mime   string    `json:"mime,omitempty"`
	Size   int64     `json:"size,omitempty"`
	Chunks ChunkList `json:"chunks,omitempty"`
}
