Public Property UseBinary As Boolean

Property Value

Boolean

true to indicate to the server that the data to be transferred is binary; false to indicate that the data is text. The default value is true.

Exceptions

InvalidOperationException

A new value was specified for this property for a request that is already in progress.

Examples

The following code example retrieves and displays property values for a specified FtpWebRequest object.

Console::WriteLine( "Passive: {0}  Keep alive: {1}  Binary: {2} Timeout: {3}.", request->UsePassive, request->KeepAlive, request->UseBinary, request->Timeout == -1 ? "none" : request->Timeout.ToString() );

Console.WriteLine("Passive: {0}  Keep alive: {1}  Binary: {2} Timeout: {3}.",
    request.UsePassive,
    request.KeepAlive,
    request.UseBinary,
    request.Timeout == -1 ? "none" : request.Timeout.ToString()
);

Remarks

If you are sending binary data, such as an image, set this property to true. If you are sending text, set the property to false. Specifying true causes the FtpWebRequest to send a "TYPE I" command to the server. Specifying false causes the FtpWebRequest to send a "Type A" command to the server. FTP servers can ignore these commands.

Changing UseBinary after calling the GetRequestStream, BeginGetRequestStream, GetResponse, or BeginGetResponse method causes an InvalidOperationException exception.
