# Message.RemoveFieldInstance

Method

## Visual Basic

    Public Sub RemoveFieldInstance(
        ByVal fieldName As String,
        ByVal instanceNumber As UInt32)

## C#

    public void RemoveFieldInstance(
        string  fieldName,
        uint    instanceNumber)

## Purpose

Remove a specified instance of a field from a message.

## Remarks

When a message contains several field instances with the same field name, remove a specific instance by number (for example, remove the `i`th field named `foo`). Programs can use this method in a loop that examines every field with a specified name.

The argument `1` denotes the first instance of the named field.

If the specified instance does not exist, the method throws an exception with the status code `NotFound.`

Parameter | Description
``fieldName`` | Remove the field with this name.
``instance`` | Remove this instance of the field. The argument `1` specifies the first instance of the named field.
