MessageQueue.CanWrite MessageQueue.CanWrite MessageQueue.CanWrite MessageQueue.CanWrite Property


Gets a value that indicates whether the MessageQueue can be written to.

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

Property Value

true if the MessageQueue exists and the application can write to it; otherwise, false.


The following code example displays the value of a message queue's CanWrite property.

// Display the value of the queue's CanWrite property.
Console.WriteLine("MessageQueue.CanWrite: {0}", queue.CanWrite);


CanWrite indicates whether the application is able to send messages to the queue. If CanWrite is true, the MessageQueue can send messages to the queue. Otherwise, it cannot.

CanWrite is false if a queue is already open with exclusive write access (or if it's open with non-exclusive access and this MessageQueue requests exclusive access), or if the application does not have sufficient rights to access it. If your application tries to write to a queue when CanWrite is false, access is denied.
