.NET Framework Class Library

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)

Syntax

Visual Basic

Public Property UseBinary As Boolean

public bool UseBinary { get; set; }

Visual C++

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

member UseBinary : bool with get, set

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.

Exceptions

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

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.

Examples

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

Visual Basic

Console.WriteLine("Passive: {0}  Keep alive: {1}  Binary: {2} Timeout: {3}.", request.UsePassive, request.KeepAlive, request.UseBinary, If(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()
);

Visual C++

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