This exception is thrown when certain operations are performed on an object that has been disposed. For example, trying to read from an I/O stream that has been closed by the System.IO.Stream.Close( ) method should raise this exception.

public class ObjectDisposedException : InvalidOperationException {
// Public Constructors
   public ObjectDisposedException(string objectName);
   public ObjectDisposedException(string objectName, string message);
// Protected Constructors
   protected ObjectDisposedException(System.Runtime.Serialization.SerializationInfo info,
        System.Runtime.Serialization.StreamingContext context);
// Public Instance Properties
   public override string Message{get; } 
// overrides Exception
   public string ObjectName{get; }
// Public Instance Methods
   public override void GetObjectData(System.Runtime.Serialization.SerializationInfo info,
        System.Runtime.Serialization.StreamingContext context)
// overrides Exception
}
