DecimalConverter Class Documentation Show file Open project: dotnet/corefx

ConvertTo() public method

Converts the given object to another type. The most common types to convert are to and from a string object. The default implementation will make a call to ToString on the object if the object is valid and if the destination type is string. If this cannot convert to the desitnation type, this will throw a NotSupportedException.

public ConvertTo ( ITypeDescriptorContext context, CultureInfo culture, object value, Type destinationType ) : object
context	ITypeDescriptorContext
culture	CultureInfo
value	object
destinationType	System.Type
return	object

        public override object ConvertTo(ITypeDescriptorContext context, CultureInfo culture, object value, Type destinationType)
        {
            if (destinationType == null)
            {
                throw new ArgumentNullException(nameof(destinationType));
            }

            if (destinationType == typeof(InstanceDescriptor) && value is Decimal)
            {

                object[] args = new object[] { Decimal.GetBits((Decimal)value) };
                MemberInfo member = typeof(Decimal).GetConstructor(new Type[] { typeof(Int32[]) });

                Debug.Assert(member != null, "Could not convert decimal to member.  Did someone change method name / signature and not update DecimalConverter?");
                if (member != null)
                {
                    return new InstanceDescriptor(member, args);
                }
                else
                {
                    return null;
                }
            }
            
            return base.ConvertTo(context, culture, value, destinationType);
        }
