BufferedStream.CanWrite Property

Gets a value indicating whether the current stream supports writing.

Namespace: System.IO
Assembly: mscorlib (in mscorlib.dll)

public override bool CanWrite { get; }
/** @property */
public boolean get_CanWrite ()

public override function get CanWrite () : boolean

Property Value

true if the stream supports writing; false if the stream is closed or was opened with read-only access.

For an example of creating a file and writing text to a file, see How to: Write Text to a File. For an example of reading text from a file, see How to: Read Text from a File. For an example of reading from and writing to a binary file, see How to: Read and Write to a Newly Created Data File.

If a class derived from Stream does not support writing, a call to SetLength, Write, or WriteByte throws a NotSupportedException.

If the stream is closed, this property returns false.

This code example is part of a larger example provided for the BufferedStream class.

if(bufStream.CanWrite)
{
    SendData(netStream, bufStream);
}

if ( bufStream.get_CanWrite()  ) {
    SendData(netStream, bufStream);
}
