public IAsyncResult BeginReceiveFile( string remoteFilename, long offset, string localFilename, bool append, AsyncCallback callback, object state )
Parameters
- remoteFilename
- The filename of the file to retrieve. Some FTP servers may be case-sensitive!
- offset
- The byte offset (of the remote file) at which to start receiving data from the remote file. If append is true, the remote file will be appended to the end of the local file no matter what the value of offset. Therefore, to implement a real resume procedure, the size of the local file must be specified in offset and append must be set to true.
- localFilename
- The path and filename of the file as it will be stored on the local system.
- append
- true if the file should append itself to the local file if it already exists; false if the local file should be overwritten.
- callback
- Callback method to be called when the asynchronous operation is completed.
- state
- An object containing state information for this operation.
Return Value
An System.IAsyncResult representing the status of the asynchronous operation.
