NetworkStream.CanWrite NetworkStream.CanWrite NetworkStream.CanWrite NetworkStream.CanWrite Property

Definition

Gets a value that indicates whether the NetworkStream supports writing.

public:
 virtual property bool CanWrite { bool get(); };
public override bool CanWrite { get; }
member this.CanWrite : bool
Public Overrides ReadOnly Property CanWrite As Boolean

Property Value

true if data can be written to the NetworkStream; otherwise, false. The default value is true.

Examples

The following code example checks CanWrite to verify that the NetworkStream is writable. It then performs a write operation on the NetworkStream.

// Examples for CanWrite, and CanWrite  
// Check to see if this NetworkStream is writable.
if ( myNetworkStream->CanWrite )
{
   array<Byte>^ myWriteBuffer = Encoding::ASCII->GetBytes(
      "Are you receiving this message?" );
   myNetworkStream->Write( myWriteBuffer, 0, myWriteBuffer->Length );
}
else
{
   Console::WriteLine( "Sorry.  You cannot write to this NetworkStream." );
}
// Examples for CanWrite, and CanWrite  

// Check to see if this NetworkStream is writable.
if (myNetworkStream.CanWrite){
   
     byte[] myWriteBuffer = Encoding.ASCII.GetBytes("Are you receiving this message?");
     myNetworkStream.Write(myWriteBuffer, 0, myWriteBuffer.Length);
}
else{
     Console.WriteLine("Sorry.  You cannot write to this NetworkStream.");  
}

' Examples for CanWrite, and CanWrite  
' Check to see if this NetworkStream is writable.
If myNetworkStream.CanWrite Then
   
   Dim myWriteBuffer As Byte() = Encoding.ASCII.GetBytes("Are you receiving this message?")
   myNetworkStream.Write(myWriteBuffer, 0, myWriteBuffer.Length)
Else
   Console.WriteLine("Sorry.  You cannot write to this NetworkStream.")
End If

Remarks

If CanWrite is true, NetworkStream allows calls to the Write method. Provide the appropriate FileAccess enumerated value in the constructor to set the readability and writability of the NetworkStream. The CanWrite property is set when the NetworkStream is initialized.
