TargetSite (inherited from Exception)	Gets the method that throws the current exception.

Public Instance Methods

Equals (inherited from Object)	Determines whether the specified Object is equal to the current Object.
GetBaseException (inherited from Exception)	When overridden in a derived class, returns the Exception that is the root cause of one or more subsequent exceptions.
GetHashCode (inherited from Object)	Serves as a hash function for a particular type, suitable for use in hashing algorithms and data structures like a hash table.
GetObjectData (inherited from Exception)	When overridden in a derived class, sets the SerializationInfo with information about the exception.
GetType (inherited from Object)	Gets the Type of the current instance.
ToString (inherited from Exception)	Creates and returns a string representation of the current exception.

Example

The following code example illustrates the basic use of the ConnectionNotMadeException class:

Visual Basic

Imports RMCLinkNET
 
Module Module1
    Sub Main()
        Try
            Dim rmc As RMCLink = RMCLink.CreateEthernetLink(DeviceType.RMC70, "192.168.0.10")
 
            Console.WriteLine("Connecting...")
            rmc.Connect()
 
            Try
                Dim data() As Single = New Single(0) {}
 
                Console.WriteLine("Reading Axis 0 Actual Position...")
                rmc.ReadFFile(FileNumber70.fn70StatusAxis0, 8, data, 0, 1)
                Console.WriteLine(String.Format("  ActPos: {0:F3}", data(0)))
                Console.WriteLine("Done")
 
            Finally
                rmc.Disconnect()
            End Try
 
        Catch ex As ConnectionNotMadeException
            Console.WriteLine("Unable to connect to the controller. " & ex.Message)
 
        Catch ex As ReadWriteFailedException
            Console.WriteLine("Unable to read from the controller. " & ex.Message)
 
        End Try
    End Sub
End Module
