System.TypeLoadException

[Ceri Lewis]

Using Rhino Mocks 3.4

I have the following in a test method:
// Setup the mock objects
MockRepository mocks = new MockRepository();
IDeliveryPeriodConverterFactory
deliveryPeriodConverterFactory =
mocks.CreateMock<IDeliveryPeriodConverterFactory>();
*** IRangeExtractor rangeExtractor =
mocks.CreateMock<IRangeExtractor>();
IDataBlockExtractor dataBlockExtractor =
mocks.CreateMock<IDataBlockExtractor>();

When executing the line with *** I get the following:
System.TypeLoadException: Method 'ExtractRanges' in type
'IRangeExtractorProxyb07f490417024a5fb04a8dc0a2cbaa1d' from assembly
'DynamicProxyGenAssembly2, Version=0.0.0.0, Culture=neutral,
PublicKeyToken=a621a9e7e5c32e69' does not have an implementation..

The IRangeExtractor interface is defined as:
/// <summary>
/// Interface for extracting ranges from a data array.
/// </summary>
public interface IRangeExtractor
{
/// <summary>
/// Extract data ranges from the specified array. Return
/// any warnings in the list of strings.
/// </summary>
/// <param name="data">Array of <b>Object</b>s to extract the
ranges from</param>
/// <param name="dataRanges">List to store the data ranges in</
param>
/// <param name="dateRanges">List to store the date ranges in</
param>
/// <param name="warnings">List to hold any warning messages</
param>
void ExtractRanges(
Object[,] data,
IList<IDataRange> dataRanges,
IList<IDateRange> dateRanges,
IList<String> warnings);
}

IDataRange & IDateRange just have a few getter properties on them.

Any ideas what the probelm could be?

Thanks

Multi dimensional arrays are not supported. There is a CLR bug that prevent this.
You RemotingMock instead, that should work

Thanks for the quick response.

So something like?
IRangeExtractor rangeExtractor =
mocks.CreateMockWithRemoting<IRangeExtractor>();

I think so, can't recall off the top of my head
