NetworkStream.CanWrite Property
Definition
Important
Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.
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.
