UploadProgressChangedEventArgs.TotalBytesToReceive Property

Gets the total number of bytes in a WebClient data upload operation.

Namespace:  System.Net
Assembly:  System (in System.dll)
public long TotalBytesToReceive { get; }

Property Value

Type: System.Int64
An Int64 value that indicates the number of bytes that will be received.

To determine the number of bytes already received, use the BytesReceived property.

Uploading data to a server may result in a download from the server. For example, suppose your application uploads a POST request to a Web server. The resulting download will update BytesReceived and TotalBytesToReceive.

To determine what percentage of the transfer has occurred, use the ProgressPercentage property. When the upload is complete, ProgressPercentage will be 50%. When the download completes, ProgressPercentage will be 100%.
