Dima C# Sample

[HarryM]

Hi,
I'm new to xServer and seek for a working C# sample code which shows who to deal with xDima.

The sample on https://xserver2-europe-eu-test.cloud.p ... ntents.htm doesn't work.
I.e. DistanceMatrixContentsOptions, GetDistanceMatrixByLocationsRequest are not found,
createDistanceMatrixResponse distanceMatrixResponse = xdima.createDistanceMatrix(createDistanceMatrixRequest); drops a NullReference error.

Pleae help!

Hello,

after struggeling around, I found an other sample using xServer, but the DistanceMatrixRespone.Contents are always NULL. How I understand there should be the response matrix. What's wrong?
Please help!

You are using CreateDistanceMatrixRequest . This is designed for calculating a dima and leave it on the server so other xServer (like xTour and xCluster) can use it. If you want to get the result you have to use the derived type CreateAndGetDistanceMatrixRequest as request.

Keep in mind that CreateAndGetDistanceMatrixRequest does not leave the dima on the server. If you need the dima to persist but still want the content you can extend your current code with a getDistanceMatrix folow-up.

Thank you!
Now it works ...
