Examples

public bool SetParameter(Parameter parameter, double value)
{
    bool result = false;
    //if the parameter is readonly, you can�t change the value of it
    if (null != parameter && !parameter.IsReadOnly)
    {
        StorageType parameterType = parameter.StorageType;
        if (StorageType.Double != parameterType)
        {
            throw new Exception("The storagetypes of value and parameter are different!");
        }
        //If successful, the result is true
        result = parameter.Set(value);
    }

    return result;
}

Public Function SetParameter(parameter As Parameter, value As Double) As Boolean
    Dim result As Boolean = False
    'if the parameter is readonly, you can�t change the value of it
    If parameter IsNot Nothing AndAlso Not parameter.IsReadOnly Then
        Dim parameterType As StorageType = parameter.StorageType
        If StorageType.[Double] <> parameterType Then
            Throw New Exception("The storagetypes of value and parameter are different!")
        End If

        result = parameter.[Set](value)
