[Visual Basic]
Function SaveFromStream( _
   ByVal startIndex As Long, _
   ByVal totalContentLength As Long, _
   ByVal segment As Stream, _
   ByVal contentType As String _
) As WebDAVResponse

[C#]
WebDAVResponse SaveFromStream(
   long startIndex,
   long totalContentLength,
   Stream segment,
   string contentType
);

Parameters

startIndex: Index in file to which corresponds first byte in segment.
totalContentLength: Total size of the resource being uploaded. -1 if size is unknown.
segment: Stream with resource content segment.
contentType: Content type of the resource.

Return Value

Instance of WebDAVResponse representing operation status.

OkResponse - the resource content was successfully stored.
NoContentResponse - the size of the resource content was truncated to zero.
LockedResponse - the resource was locked and client did not provide lock token.
ResumeIncompleteResponse - the upload was not finished.

Remarks

If totalContentLength is -1 the segment parameter contains entire resource content. The startIndex parameter is always 0 in this case.

Example

 
public WebDAVResponse SaveFromStream(long startIndex, long totalContentLength, Stream segment, string contentType)
{
    if (!ClientHasToken)
        return new LockedResponse();

    long read = 0;
    try
    {
        read = WriteContent(segment, contentType, totalContentLength, startIndex);
    }
    catch (HttpListenerException)
    {
        //We came here because there were troubles with connection.
        //We want to keep content but return ResumeIncompleteResponse,
        //so engine knows we havn't finished uploading.
    }

    if (startIndex + read < totalContentLength)
    {
        return new ResumeIncompleteResponse();
    }
    else if (read > 0)
    {
        return new OkResponse();
    }
    else
    {
        return new NoContentResponse();
    }
}
