FtpWebRequest::UseBinary Property

Gets or sets a Boolean value that specifies the data type for file transfers.

Namespace:  System.Net
Assembly:  System (in System.dll)

public:
property bool UseBinary {
	bool get ();
	void set (bool value);
}

Property Value

Type: System::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.

ExceptionCondition
InvalidOperationException

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

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.

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