方法

	名称	说明
	Approve	Approves the file submitted for content approval with the specified comment.
	CancelUpload	Stops the chunk upload session without saving the uploaded data. If the file doesn’t already exist in the library, the partially updated file will be deleted. Use this in response to user action (as in a request to cancel an upload) or an error or exception.
	CheckIn	Checks the file in to a document library based on the check-in type.
	CheckOut	Checks out the file from a document library based on the check out type.
	CheckUninitializedProperty	Checks to determine whether the specified value type property of a ClientObject has been initialized. （从 ClientObject 继承。）
	ContinueUpload	Continues the chunk upload session with an additional fragment. The current file content is not changed.
	CopyTo	Copies the file to the destination URL. Server must overwrite an existing file of the same name if bOverwrite is true.
	CustomFromJson	Returns a Boolean value that indicates whether custom code was used to populate an object. 此成员仅供内部使用，不能直接在您的代码中使用。 （从 ClientObject 继承。）
	DeleteObject	Deletes the file object.
	Deny	Denies approval for a file that was submitted for content approval.
	ExecuteCobaltRequest
	FinishUpload	Uploads the last file fragment and commits the file. The current file content is changed when this method completes.
	FromJson	Indicates whether custom code was used to populate an object. 此成员仅供内部使用，不能直接在您的代码中使用。 （从 ClientObject 继承。）
	GetContentVerFromTag	Reserved for internal use only. This method exposes the internal ContentVersion value inside of a ContentTag.
	GetImagePreviewUrl
	GetLimitedWebPartManager	Specifies the control set used to access, modify, or add Web Parts associated with this Web Part Page and view.
	GetPreAuthorizedAccessUrl
	GetWOPIFrameUrl
	InitNonPropertyFieldFromJson	Initializes a non-property field of the client object based on JavaScript 对象表示法 (JSON) data from the server. 此成员仅供内部使用，不能直接在您的代码中使用。 （从 ClientObject 继承。）
	InitOnePropertyFromJson	（覆盖 ClientObject.InitOnePropertyFromJson(String, JsonReader)。）
	IsObjectPropertyInstantiated	Indicates whether the specified property of the client object is instantiated. （从 ClientObject 继承。）
	IsPropertyAvailable	Returns a Boolean value that indicates whether the specified scalar property has been retrieved or set. （从 ClientObject 继承。）
	LoadExpandoFields	Initializes the extended properties associated with the client object when overridden in a derived class. （从 ClientObject 继承。）
	MoveTo	Moves the file to the specified destination URL.
	OpenBinaryDirect(ClientContext, String)	Downloads the specified file from a SharePoint site without requiring an ExecuteQuery() method call.
	OpenBinaryDirect(ClientContext, String, EventHandler<OpenBinarySucceededEventArgs>, EventHandler<OpenBinaryFailedEventArgs>)
	OpenBinaryStream	Opens the file as a stream.
	Publish	Submits the file for content approval with the specified comment.
	Recycle	Moves the file to the Recycle Bin and returns the identifier of the new Recycle Bin item.
	RefreshLoad	Reloads all scalar properties associated with the client object when overridden in a derived class. （从 ClientObject 继承。）
	RemoveFromParentCollection	Removes the current client object from the parent client object collection. （从 ClientObject 继承。）
	Retrieve()	Retrieves all scalar properties associated with the object. 此成员仅供内部使用，不能直接在您的代码中使用。 （从 ClientObject 继承。）
	Retrieve([])	Retrieves the specified scalar properties associated with the object. 此成员仅供内部使用，不能直接在您的代码中使用。 （从 ClientObject 继承。）
	SaveBinary	Saves the specified file into a document library.
	SaveBinaryDirect(ClientContext, String, Stream, Boolean)	Uploads the specified file to a SharePoint site without requiring an ExecuteQuery() method call.
	SaveBinaryDirect(ClientContext, String, Stream, String)	Uploads the specified file to a SharePoint site with the specified Etag without requiring an ExecuteQuery() method call.
	StartUpload	Starts a new chunk upload session and uploads the first fragment. The current file content is not changed when this method completes. The method is idempotent (and therefore does not change the result) as long as you use the same values for uploadId and stream.The upload session ends either when you use the CancelUpload(Guid) method or when you successfully complete the upload session by passing the rest of the file contents through the ContinueUpload(Guid, Int64, Stream) and FinishUpload(Guid, Int64, Stream) methods.For example, you can pass a 35 MB file by dividing it into three 10 MB streams and one 5 MB stream and uploading them this way (using the resulting offset values of 10, 20 and 30 MB):StartUpload(GUID, stream1) ContinueUpload(GUID, 10 MB, stream2) ContinueUpload(GUID, 20 MB, stream3) FinishUpload(GUID, 30 MB, stream4)The StartUpload(Guid, Stream) and ContinueUpload(Guid, Int64, Stream) methods return the size of the running total of uploaded data in bytes, so you can pass those return values to subsequent uses of ContinueUpload(Guid, Int64, Stream) and FinishUpload(Guid, Int64, Stream)
	ToString	（从 Object 继承。）
	UndoCheckOut	Reverts an existing checkout for the file.
	UnPublish	Removes the file from content approval or unpublish a major version.
